Old C64, Amiga 500, Amiga 1200 user here (1989 onwards). After your videos, I kinda realized I was conned by the popular media that Apple I, II. Lisa, Mac etc were unique, revolutionary machines in 1977, 1982 etc. Your Commodore history clearly demonstrates Apple had many strong competitors. I understand that Woz and Jobs were visionaries. But there were many others with the same vision. In particular, Amiga developers were amazingly ahead of their time! (That's why I'm looking forward to hearing your story of it). Even Commodores up to and including C64 were amazing machines for their time. Cheers.

[@lovemadeinjapan]

I would put Atari in between on the visionary ladder. Their 1979 Atari 800 outperformed the C64 at launch, which is really amazing. Also the ST was a way more solid product than the Amiga and revolutionaired the music business. Commodore really was popular because they were above all cheap.

[@bitset3741]

@@lovemadeinjapan Big fan of both machines, and have both, but the 800 does not outperform the C64. The C64 has a better video chip in many ways - better sprites, had color ram etc. and a better sound chip in the SID (Arguable, I love Pokey Bass and game sounds) but the 800 had a faster CPU. And it could use that CPU to multiplex sprites and do scrolling etc. fast enough to roughly equal the C64. When JUST doing computations - yes the 800 did outperform the C64, but not when running Basic - Atari Basic is fully featured - better than Commodores Basic 2.0, but was notoriously slow.

[@lovemadeinjapan]

@@bitset3741 And then C64 BASIC was horribly slow compared to its peers. Atari Basic must be really bad then. Not to mention C64 BASIC is total garbage to use. And SID.... It was a good starting point to found Ensoniq, but I never liked it as music chip in a computer. A bit like the pine nuts... Nice at first, but always the bad aftertaste. I feel I get brain rot of SID sound.

[@bghoody5665]

I remember my high school computer lab being set up very similarly to that at 0:45 - one disk drive servicing multiple computers (PETs iirc). We'd have to shout "accessing" whenever we'd access the disk drives because if more than one computer were to access it at the same time, it would crash the system.

[@AlexWMY]

We had other computers, but a similar setup. At the beginning of the lesson, we loaded them strictly one after another. Now that would be so funny.

[@TourmeisterTWT]

Wow! I had completely forgotten about having to do that! We had them when I was in the 9th grade in 1980. The teacher would go nuts if you forgot to do it!

[@melkiorwiseman5234]

If I remember correctly, the IEEE-488 protocol included a way for multiple "bus masters" to coordinate with each other to share a peripheral over IEEE-488, but fairly obviously that standard was ignored by Commodore because they originally did not expect drives to be shared. Possibly also, they couldn't justify the extra expense required to have someone program the protocols into both the drives and the computers.

@@AndersEngerJensen I love your work, but I have to question if you had a CD-ROM drive in 84 when they where first released, or was it much later in the 90's? Because in the 80's having an HDD, or CD-ROM drive was very expensive, so yeah most people used floppies 5.25in or 3.5in, or tape drives. it was not till around the IBM 286 machines where HDD became more common place upgrades in IBM and clones.

[@davidinark]

@@glitchvomit Not sure if you're asking seriously or being facetious, but copy parties were a gathering where people would bring their games, applications, etc (some home-brewed, more often pirated commercialware) to someone's house along with their drives and c64s to copy everyone else's disks. Folks would spend hours together watching and waiting for their copies to get done, trying to figure out various copy-protection hacks, copying (usually by hand) various keycodes, dialing up BBSes for research and forum chats, etc. It was awesome!

[@glitchvomit]

@@davidinark oh no i was being genuine! thanks for the explanation ^_^

[@nobytes2]

I find this series just amazing. A time when PCs took off, programmers really had tons of limitations like ram / graphics / cpu speeds. Things we just take for granted nowadays. I actually didn't have access to a computer until I joined the US Navy as I grew up in Mexico, public schools weren't setup with computers. Ha I had barely seen any computers at all. In the Navy 2004-2008 Arleigh Burke class destroyer still had tons of old equipment like magnetic tape recorders, floppy disks drivers, even dot matrix printers. Really is where my love for software started. I hate that I didn't have this growing up but I guess things happen for a reason.

[@TheJeremyHolloway]

[@poitsplace]

Anyone remember Vorpal Utility kit?

[@MicroFourThirdsCorner]

Great video. Brought back a lot of memories. I have to admit I was one of the programmers that wrote the turbo loaders, custom disk formats and copy protection systems using the internals of the 1541. I left that (full time) job to move on to programming and then designing high speed floppy disk duplicators and ultimately CD/DVD/BD duplicators. That's now ancient history too, so this was a nice walk down memory lane. Oh, and yes, I got grief from customers who bought the "compatible" disk drives that ultimately didn't work with my disks, especially those that didn't provide the Block Execute command available on the 1541, which was how I started the loading sequence happening from the 1 (and only 1) tiny file ever to be seen in the directory. Everything else was direct block access. Oh well, nostalgia at it's best! Thanks again!

[@jasonteknut]

Wow that's an impressive collection of Commodore disk drives...

[@reelmccoyfx]

My 1st experience with a 1541 was entering the disc testing program out of the manual and running it. 1.5 hours later, the 1541 stopped working due to overheating and warping the flywheel. Ooops! Next day, an MSD single was put in it's place and that sucker was a rugged.

[@MatroxMillennium]

[@KuraIthys]

The only 8 bit I've ever owned at a time when they were still vaguely relevant (1990 - when they were well on their way out) was an 800XL. I actually appreciate the design of this series of machines a lot more now than I did then. They can do some really crazy things if you push them. Though it probably doesn't help that at the time I had been told (And believed, stupidly) that the PAL versions of the Atari computers wouldn't work with PAL televisions, only special monitors. (ironically given the cabling I had this might 've technically been true.) As a result I spent my entire original time with these machines viewing it on a monochrome green display... Even though there was a television on the same desk that could have shown it in full colour. I don't have my old ones, but I do have a replacement since about 3 years back. Another 800XL, with a tape drive (XE era tape drive though) and a floppy drive that I never owned back in the day...

[@vwestlife]

David is a big Commodore guy, so he probably doesn't want to admit all the aspects in which the Atari 8-bit computers were equally as good as or even superior to the C64 despite being a much older design (1978 vs. 1982). :-)

[@gamedoutgamer]

@@vwestlife So true. A8 has many superior features indeed! While the 1541 was DD which was nice, at 3:02 I was face palming yet again at this C= design using 'bad lines'. I appreciate the honesty, knowledge, diagrams and historical context expressed in this video. =) I got an 810 drive a couple months ago and love it.

[@TheJeremyHolloway]

@@vwestlife yeah but any 8-bit Commodore fan who later became a rabid Amiga zealot has to give credit where credit is due since Jay Miner, Joe Decuir, and several others designed both the Atari 8-bits and the Amiga. A lot of Commodore's engineers went over to Jack Tramiel's TTL/Atari Corp after he left Commodore and they were responsible for designing the ST's hardware even though a lot of ex-Atari Inc programmers worked on the ST's OS and supporting software. Thus the Amiga is more of an Atari machine while the ST is a Commodore/Atari hybrid. There wasn't a pure "Commodore" successor to the C64/C128 line. Wah wah...

[@TheJeremyHolloway]

there's still a bunch of Atari 8-bit development going on. You can see a lot of it over at AtariAge proper or at the Atari Museum and Atari 8-bit groups on Facebook.

[@grotekleum]

You missed out a drive that I had, a Commodore SFD 1001 1Mb that ran (I think) double density 5.25 disks. I had a 240v to 120v transformer and it had a different interface that plugged into the cartridge port of my CBM 128 with an IEEE-488 plugging into the drive. I used it to run Superbase 128, that was available on this drive, for a charity membership/subscription database. Happy days. Thanks for sharing.

[@RacerX-]

14:12 the 1541C was a unique drive. I have 2 bought back in the day and they both have a turn type newtronics mechanism. Not sure if yours with the alps was uncommon. But I do know they they were more then just a color change. They also have a track 0 sensor although it is disabled from the factory. The true 1541C drive will knock the head at power on and reset. The drive motor will also spin when you insert and remove a disk, like the 1571. There are jumpers on the logic board to enable the track 0 sensor (or Zero Stop as it is also called) and then the drive does not knock any longer. Not sure why they disabled it from the factory as I have had mine enabled for years with no problems. Supposedly it was for compatibility reasons. They also created a more integrated logic board, which is the shortest of the full size 1541s. The ROMs on the 1541C also fixed the SAVE@ save with replace bug.

[@hyperslime64]

I actually have one of those drives, and I was terrified when I heard the disk knocking on boot. Do you know how to turn the sensor on?

[@RacerX-]

@@hyperslime64 It's a jumper/solder pad on the board you have to cut I believe. Edit: it is J3 you have to cut. There are three jumpers, 2 are for device number select and the other is for enabling the track 0 sensor (some also call it the track 1 sensor because Commodore disks start with track 1 but it is the same) It won't knock anymore after that. That said I these drives don't really got out of alignment as much as the alps ones did. The knocking on my 1541C was not nearly as loud as on my old 1541 alps drive. If you were an Apple II user the knock was part of life as those drives knocked at bootup from the beginning.

[@hyperslime64]

@@RacerX- Well, upon further searching on the interwebs, I heard that only the lever (Nutronics) mechanisms have the sensor... and I have a 1541C with the pop (Alps) mechanism. I'm guessing those don't have the sensor, but I could be wrong...

[@RacerX-]

@@hyperslime64 Yep that is correct. From what I have seen only the Newtronics mechanism 1541C models are "True" 1541C models with the improvements. The Alps models use an older revision board with the newer case color style. Good old Commodore! LOL. However, if yours knocks when you power it on then it probably has the newer ROM. So you could swap out the ROM with the one from the 1541-II and that would at least stop the knocking on Power Up. It won't for disk errors and such but it's better than nothing.

The CMD FD2000 drive was awesome, so many features and modes. The ability to create 1541 simulation partitions was very useful. It always bemused me why the 1541 was so slow, when it could be sped up so easy with a turbo catridge

[@kmabru]

Agreed that it was awesome. I had one and as an experiment, I formatted a disk as one big partition and copied the files from all disks for Pool of Radiance over to the one disk. I was surprised when it actually worked. It even fixed the problem with the bug for one of the missions. I forget which one it was, but you could finish the game without doing that one. If you did it, you couldn't continue with anything else due to a corrupted file. I also had the RAM drive add-on for the C64 (I forget exactly what it was called). That was another awesome device.

I've seen plenty of drives out there with extra switches - mainly for device selection - and i always thought the best place to put it was on the front lower right kinda opposite where the green power LED was. That way the lid could be removed for servicing and not have to worry about wires attaching the top case if the switch happened to be there. But then again, I *gasp* drilled a hole and put a reset button on my breadbin 64 too.... :) Dave does really good work in making his equipment put on youtube look as pristine as possible - and that can be a challenge because these were considered expensive but common "back in the day"...

[@cnhawk8371]

Thanks for this episode. Brought back OLD OLD memories. I went from the VIC20 straight to the C=128 as I always hated the breadbox design... bulky and painful to use. The C=128 was sleek, and so 80's designed. When I finally saved enough for the floppy drive, I got the Enhancer 2000. It was cheaper than the 1541, faster, smaller and cute. I loved that drive. But - one day, one of my C=64 games wouldn't work, tested it on a friends C=64 set up... and it was the drive compatibility problem! Because it was the 80s, stores like Toy'r Us, Sears and Target had 90day returns. By chance, I had my receipt the discovered the problem on day 89 and took the Enhancer2000 back to Target on the 90th. I bought the 1571 at the Target, it was $280+ tax. I loved my 1571, modern and fast. Still have it in a box, looks almost new. C=128 turned yellow. :( Likely won't power up. Still have my Amiga 1000 and 3000.

That switch on the back of the MSD drive is most likely an override copy protection switch. So you can copy a disk without having to have a notch on the disk. Great for making professional looking copies of software. Without having to notch the disk.

Great video, as always. I think one awesome drive system left out was the Lt. Kernal HDD system by Xetec. As a BBS operator, that 20MB hard disk was a game changer for my Commodore 64 life.

One of the things I did was add a chip to the 1541 and a speed controller. Could you go into some of the mods and accessories that were around at the time such as what I mentioned? Also it would be fun to see some of the interesting peripherals that came out for the C64 like joysticks, touch pads (Koala Pad) and even some strange and fun cartridge addons like BBUs and MIDI controllers.

[@LivingInAVan]

Very nice documentary and research. I actually learned quite a bit from this video. Awesome job!

[@berczigabor]

The switch on the back of the MSD drive might be one that makes the drive ignore the write protection cutout and allow you to write on a non-cut disc anyway. At least that was a very popular mod on these drives. If the switch does that the wires from it usually go straight to the write protection sensor.

[@Tditty46]

Man your videos are one of the most relaxing and satisfying things in my life right now ! Well that and Weed. Keep up the great work !

[@richard1113]

Totally loved the appearance of the Indus GT! I had one of these for my Atari computers and loved it. Was way cooler than the Atari disk drives with its two digit display, and as I recall, faster as well.

[@carlstenger5893]

Once again, a splendid video! Prior to jumping ship to run IBM compatibles, I was heavily into the Commodore ecosystem. Somewhere in my garage, I have at least one Vic-20, 2 or 3 C64s, 1 Plus4, and at least 1 C128. One of these days (sooner rather than later) I need to locate those systems. Thanks a lot for your multi-part videos on the Commodore history. I've enjoyed watching each and every one. Incidentally, though I live in Albuquerque now, from about 1977 until 2002 I lived in the Fort Worth / Arlington / Mansfield / Kennedale area. I've traveled back to that area a few times over that last 18 years and I can't believe how much that area has grown.

[@fremandn]

After the end of each episode, I imagine The 8-Bit Guy walks back to a warehouse that has the Ark of The Covenant in it right next to the rest of his collection

[@Megatog615]

dude the music you put in your videos when you're explaining things is so good i am compelled to turn it up at those times

[@Megatog615]

oh my god when you're talking about the 'typical floppy disk' and the sectors light up in tune with the hat n u t

[@lochinvar00465]

I remember when I finally ended my 1541 head banging. Can't remember if it was a feature of my fastload cartrige or a simple drive commend. I also had three switches added to my drive, two for device select and the other for write protect override. I currently have a 128 with a 1571 that needs a head replacement but otherwise is fully functional. Curiously, I usually used it in C64 mode. One game I had (Echelon) was on a double sided 1541 disc and I made a copy of it on a 1571 disc which meant that I didn't have to manually flip the disc during the game. It was one of the very few "non-protected" games.

[@deljohn]

Great video on the Commodore (and other) drives. I interned at Commodore in West Chester, PA from 1983 to 1984 and there were a few of the VIC 1540 drives laying around. Who knew they'd become collectors items... Also, I had a chuckle when you mentioned the MSD drive was popular at copy parties. We had a CBM 4040 drive hooked up to a PET computer on the floor that we used to copy C64 disks in a similar manner.

[@bwc1976]

Crazy how the old Commodore factory is now the QVC studios!

[@mxims97]

I've been watching his videos for 5 or 6 years now and I just realized that The 8-Bit Guy painted his room with the same 2 shades of blue as what are on the C64 display!

[@BillAnt]

Imagine covering your walls with a large C64 Basic screen wallpaper. ;D

[@andrejszasz2816]

22:55 I have a disk drive Oceanic OC-118N, which looks identical to the Excelerator that you show here. It worked great! The led was also dual color so it had a funky green-orange-red color transition with the pwm led flasher tiny software 😃

[@hipwave]

when I built my c64 station I went straight for a couple of 1571 drives, never looked back after that. even with the slow speed they are immensely superior .- and GEOS lives better with larger disks.

[@coolpoete]

If there is one person who could make a video about Disk Drives interesting is this guy. And I've never owned a commodore! Love your videos man!

[@DIYTechRepairs]

In beginning you talked about history about Amiga 500 as well. Do you still plan to release that and if so when? I highly appreciate your videos btw!!

[@johngaltline9933]

I have most of these drives and fond memories of them all, As a part time programmer of software for the Commodore and die-hard data hoarder, my father tended to buy the highest capacity drives he could. Still have hundreds of 1581 disks with no idea what is on many of them. The CMD 40Mb HDD was the real game changer, later upgraded to an 80MB drive.

[@DancesWithRobots]

When I noticed how hot my early 1541 was getting, I put rubber feet on a 5" equipment fan and parked it permanently over the vent holes.

[@travisjohnson8146]

Wow. I did that exact thing.

[@ziggys745]

thanks for the trip down memory lane and the details of the drives. we used the C64 with 128K expansion cartridge and 1541 drive and printer to for school work probably up to 1990. It was a great setup, I wish I kept it.

[@HelloKittyFanMan.]

Oh yeah, when our 1541 sadly died to the point of being "unrepairable" (I mean from before I grew up and bought my own), we (the family headed by my parents) bought a Blue Chip and then that Indus drive! The GT is pretty fascinating!

[@HelloKittyFanMan.]

Yeah, @Chef Mike Rowave, like the 9090. Not designed specifically for the 64, but more for the PET and then stayed compatible for the 20 and 64.

[@rbrtck]

I had and still have a Blue Chip drive (purchased from Best) that has been utterly reliable and extremely compatible with the 1541, albeit this is not true of the earliest models. It also has a green write indicator light, which I occasionally find informative. I considered the Indus GT because it was already legendary in its own time and looked so cool (and I really like the track indicator), but I don't think it is nearly as compatible as the Blue Chip. If it has a Z80 CPU instead of a 6502, then it really is much less compatible for sure. For those who primarily used pirated software, it was mostly fine, but a lot of commercial software with original disks would not work on it, and any titles that used their own fastloaders would either fail or have to turn off their fastloaders. If your experience has been different, then let me know. I still like the GT, and am thinking of buying one for my Atari 8-bits, since software compatibility does not appear to be an issue in that case.

[@dembalachannel]

One of your best ever videos. Amazing background info on these and details I love. I was a commodore 64 user in my childhood but wasn't even aware of any 3rd party disk drives existed at the time. Congratulations and thanks for the memories :)

[@artistwithouttalent]

19:15 Commodore users: Hey what are these aux ports here for? Indus: It's a surprise tool that will help us later

[@mattandsarahaschan]

Ah, I see another Mouskateer!

[@warp9988]

I loved learning about the custom loadstar dual 3.5" drive. Looking forward to the Amiga episode. This is a really fantastic coverage of the topic and although I lived through and was aware of almost all of these being live products you could buy and which friends of mine owned, I never owned most of these drives. I did own a 1581 drive. I won it at a raffle at a commodore user group. Going back to the Commodore PET era's drives, I was given a Commodore PET 8032 and a dual IEEE 488 drive, and I actually did something that most people didn't ever do on a Commodore 64: I Tried to use an IEEE 488 interface to connect these PET drives to my C=64 to use as a BBS storage subsystem. I used a cartridge from a company based out of Canada called Batteries Included. I think it was called the BusCard or BusCard II, but I can't remember what it was called. I only found the name BusCard by googling. I do remember it was from batteries included and that it looked like this somewhat: mikenaberezny.com/hardware/c64-128/buscard-ii-ieee-488-interface/ I also owned the 80 column video card for Commodore 64 that was built by Batteries Included. The commodore product to interface commodore 64s to an IEEE488 was something I never saw ever in my life.

[@jbevren]

Regarding the Indus GT, the Atari version used a z80 processor and could be used to run cp/m directly on the drive with a ram expansion while the Atari computer acts as a terminal. The extra port on the rear of the Commodore version is actually a parallel port wired to both ports. These go to the VIA port that would normally be unconnected on a 1541 drive through a bus transceiver whose direction is controlled by CB2 and enable controlled by CA2. When fixing my unit some years ago I spent time to trace these lines on the pcb. This could have made for a good parallel loader with the user port. Interestingly, my unit doesn't have the 1: drive as it has the 1541 version of jiffydos in it.

[@shawnrainer]

I was an Atari 800xl kid and didn't have any friends who rocked a C64. I dig this series and am fascinated with the engineering that went behind Commodore tech. Thank you for posting!

[@lovemadeinjapan]

Lucky you. Somehow Apple and Atari did not succeed across the pond. I would love to pick up an Atari 800, but they are impossible finds in PAL.

[@ChristopherGaul]

Great installment in the series. Though I would have liked to have seen the SFD-1001 included. That drive was highly coveted by Commodore BBS operators.

[@isubsmith1]

Agreed; I had 2 of them and a 1581 on my BBS. I was actually surprised it wasn't discussed.

[@drewpt]

Came here looking for this. I also had a couple for my board.

[@bwc1976]

Yes I was waiting for that one! The first high density drive I ever heard of. Also there were one or more third party hard drives released such as the Lt. Kernal.

[@CesareVesdani]

I really like disk drives. They are amazing.

[@DeputatKaktus]

Yet again, another awesome video :-D By the way, I love that "Commodore Security" patch.

[@timsmith2525]

Very thorough presentation. Thanks!

[@authorlilhyz7121]

No

[@rodneylives]

This brings back so many memories, it reminds me of things I didn't know I knew.

[@TonyPadgett]

If my memory serves me correctly, I had a very critical issue with the 1571. When it started writing to the 2nd side, the head would reset frequently. I took it to a generic computer repair shop and they had not idea how to fix it.

[@tonybossaller4074]

The MFM on the 1571 makes a lot of sense. I purchased two ICT DataChief hard drives. One was epoxied to hell and back so you couldn't really see the board, but my first one was bare. It was a plain 1571 motherboard with an 8-bit ISA MFM card attached. This connected to standard MFM hard drives like the Seagate ST-225 or Tandem's clone of it. I also own a Lt Kernal hard drive but it used the SCSI version of the ST-225. So I have one of each that currently (well last I checked) worked. My ICT DataChief however is VERY susceptible to random power differences (and I think mine, both, were grounded improperly. Not enough to shock but overtime if you were leaning on it, for example, your arm would lose sensation over time. This mine stayed on a UPS all the time.) I also have the SFD-1001 drive as well as a few 8080s though I think only one works still. Speaking of the ICT DataChief, I never owned but saw the MiniChief in person. As I recall, they basically used the 3.5" drives (most were 5.25 at that point) and crammed it into the bottom of the 1571 case, and the plethora of wires ran up to the drive controller from the ISA MFM card. (The PSU was removed the drive to make the space available.) I could go on and on about the DataChief as it ran my BBS for about five years and I worked with ColorBBS 64 and128 versions to implement directory management. Things like chaining partitions together, rearranging files between those partitions, etc. But the ICT drives still had a working 1571 which was treated as partition 0 and could be selected. Amusingly enough, the drives were fully 1571 compliant, allowing the drive to be formatted as 120 1541 partitions or 60 1571 partitions (odd only, even partitions wouldn't have data on track 18. And it started with partition 1 because 0 was the 1571 itself.)

[@BartoszPe]

Hey David, This video is pure gold and one of the best you've made. I've been listening carefully to the highly interesting tech stuff but unintentionally i focused on something else. I was always amazed how much attention did Atari and Commodore devoted to the visual aspect of their product lines. After this footage I'm even more astonished. Could you possibly focus on this topic in one of your future videos? I would love to see those XL/XE as much as C64/C64C wide product lines matching each other visually. Thanks in advance!

Excellent video David Murray. Very informative and even as a commodore user/collector from way back I still learn new things from you. Amazing. Including 8-Bit Show and Tell (aka Robin H) made it twice as good! Hope you guys collaborate in the future.

[@bozimmerman]

Fantastic video. Learned so much about those third party drives! Some info about the 1581 though: Metal Dust (a SuperCPU 64 game) was shipped on 3.5" disks. Also, as your guest showed, LoadStar (and other disk magazines) offered 3.5" issues after 1988.

[@TheJeremyHolloway]

Metal Dust uses the 65816? Sweet. How much REU RAM does it use?

[@bozimmerman]

@@TheJeremyHolloway None. Instead of using the REU, it used 4MB of the SuperCPU's 65816 ram,.

[@Ardonyx]

I didn't want the video to end, learning about drives was just fascinating!

[@zemmel63]

Thank you for this great episode. I love the "History" videos😍 Greetings from Germany😀

[@Procket12]

Nice putting in footage from Project: Firestart AKA probably the first Survival Horror game. I found out about it a few years back and I have to say, it is absolutely phenomenal, especially being what it is. A C64 game in 1989, when Commodore's own Amiga was already out in addition to all the IBM-PC Compatibles. It's a great example of doing more with less.

[@aphexteknol]

One thing I’ve always wondered about was why the model designation on the brown 1541 drives were written in a font that makes it look like “154I”. The second 1 is different than the leading 1 and looks a lot like an I or lowercase L or something. Always bothered my OCD since I was a kid...

[@bwc1976]

Same!

[@3rdFloorblog]

I remember some games used the head banging error for copy protection therefore a few copied games, you would have to pop the floppy open and close it at the right place for the game to load. This was a great trip down memory lane...thanx!

[@Gencoil]

Ever notice there's a slight southern accent leaking out sometimes when he says "drive"? :)

[@robspiess]

He lives in Texas and has a texan accent. e.g. notice the emphasized "h" sound in wh-words, like "white" (hh-wite instead of wite).

[@thegardenofeatin5965]

He's Texan. He's allowed to drawl and/or twang.

[@CommodoreFan64]

You want some real southern accents come over the SC, GA, and NC. I'm from SC right on the GA border, and have family from NC, and as a kid even I could sometimes not understand 1/2 of what some of the really old timers where saying.

[@Iliek]

Dallas is not Texas. They're basically yanks.

[@robspiess]

Do you mention people in the UK having a British/Scottish/Irish/Welsh accent? "Ever notice his accent leaking out when saying 'herbs'? :)"

Loving this series. Nice 1551 too, mine is one of the jewels of my collection. Looking forward to the Amiga video!

I just watched this whole series, and man, how computers have changed. I would've loved to have been along for the ride.

[@parallaxgames]

I enjoyed this, but I would have appreciated it if you had touched on the internal drive of the 128D.

[@HelloKittyFanMan.]

Yeah, the "1571-D," about like the "SX-1541" and the Commodore 65's 1581 or whatever that drive is. Plus covered the SFD-1001, 2031s, as well as the whole PET series and Amiga series (even though that would be putting the cart before the horse for the Amiga computers themselves -- but he did just say "disk drives"). Oh, as well as hard drives for both lines (including the 9090 for 8-bit).

[@GadgetUK164]

Wonderful video =D Always love the detail you go to!
