I read “The Soul of a New Machine” in 1981 and it gave me inspiration to study computer engineering at Rensselaer Polytechnic Institute. Great read; you will quickly empathize with the lead designer. A lot of the work you do in the digital basement reminds me of the early debugging days presented in the novel. Enjoy!

It's a great book, and goes great alongside The Mythical Man Month, Where Wizards Stay Up Late and Hackers.

​ @Kristian Van Der Vliet My American Lit. professor assigned the book in 1988. Another from that class was The Handmaiden's Tale. I'm grateful he was so prescient. I read Hackers when my ex got a job at Symbolics (that was interesting). "The Pragmatic Programmer: 20th Anniversary Edition" by Hunt and Thomas, like Mythical Man Month is nonfiction and might be a little dry for non-techies, although another classic in that vein.

The Macintosh LC was originally designed with schools in mind. It was easier for teachers to give kids a new boot disk when needed, like the old Apple II days, then to constantly administer a hard disk. Because the Mac was so inexpensive, it was popular with home users. You only find dual-floppy LCs from schools. Also, the 68881 FPU can run at a separate speed from the CPU. The LC II was basically what you have here: a 68030 in an LC. The main benefit was the MMU for virtual memory. Very useful for schools who couldn’t splurge on RAM which was incredibly expensive in the 80’s and 90’s.

Hot air gun on that memory chip, put a small amount of solder on top of it. 20 seconds after it melts the solder under the chip should melt as well. Also some liquid flux around the chip will help reflow any cracked solder joints. Aliexpress sell a temperature controlled hot air rework station for £20. It's well worth learning soldering SMD chips and components and it's not too hard to do after a bit of practice with the right equipment. You can even buy kits of chips/components and boards to practice with for about £1-50

Lindt makes a wide range of truffle chocolates. Dark chocolate (My favourite), a white chocolate one with cookie bits in it, peppermint crunch, and toffee crunch ones as well.

[@TzOk]

Recently I was repairing an LC II, and its 80MB HDD had a head stuck to the limiter/bumper. There was a rubber insert in this bumper, which transformed into a chewing-gum like substance. I've managed to remove it and replace it with two layers of a double-sided foam tape, with a protective film left on the top side. Without this tape the head would crash into the platter hub. The drive is now working, without any bad sector. I've formatted it and verified using a Silverlining software, which I've seen on your channel, thanks for that hint. Macs are really rare in my country, and this was the first one I had in my hands, so I had no idea what software to use. Strangely it had a Polish keyboard (which is really odd, as we use US Intl. layout), and had System 7 in Polish (with a very strange terminology/translation).

[@raelik777]

Yeah, your take on the Odroid Go is 100% spot-on. I just got one of these, already owning 2 Odroid Go Advance handhelds (much more capable RK3326-based Linux handhelds), and it was specifically for the purpose you realized: custom programming with the Arduino sdk.

Hello Adrian I really enjoy your videos and the time you must put in to create them. You may have been disappointed not to get the Mini C64 working but I was really impressed with your skills to work out those pins were a serial interface and to know how to connect it and what baud to at least get to the diagnostic to tell you what is wrong. I learn a lot from your videos. I'm afraid my troubleshooting is usually limited to turning things off and on again! As to the C64 keyboard you probably know this already but I am in the UK, so Shift+2 is the usual key to use to get double quotes on a PC here in the UK, it's standard UK layout. This makes me wonder if C64s sold in the US had the same keyboard layout as in Europe. If so it seems surprising that Commodore, as a US company used a UK keyboard layout globally though of course at the time there wasn't really a "standard" layout anyway.

The IIci was top of the line in 1989. The only Mac faster was the IIfx, and that didn’t come out until the following year and was more than twice the price. The LC was heavily compromised, certainly, but Apple eventually got that model right with the LCIII, which was a fantastic little machine.

[@0toleranz]

Hey Adrian, with the SD RAM chip it’s not that hard to repair - just a hot air station and the proper amount of flux to remove the dead chip - then a little cleaning with more flux and desolder braid - and then a bit less flux and a new chip. I made my first (Louis Rossmann style) try to swap out a FBGA 256 one week before christmas and it did fail first try but worked the 2nd time. I suspected some pads didn’t made contact or shorted but it really wasn’t to hard. I never did much smd work at all before that but I guess it’s the way we have to go sometimes as long as it’s still possible to repair stuff. Greetings from Germany, keep up the great content you create - its really fun to watch!

[@CanuckGod]

We have several varieties of Lindt Lindor balls here in Canada. One of the rare ones that I found to be my favorite is the ones in gold wrapping, chocolate with the same milky creamy center, but in this case the gold one is sort of a caramel cream. I'm not overly fond of straight up caramel in chocolates, but the texture and flavor of the creamy caramel is extremely addicting. We also have those "Riegel" here too, but they're just called Kinder T1 - basically a Kinder egg in bar form - though I've never heard the milk cream insides referred to as "marshmallowy"...

[@ViewtifulSam]

Great episode! That generic case the ODroid came in is probably meant for consoles in the DS family

[@Colaholiker]

I think the reason for Germany being so far up in the list of countries where your viewers come from despite people here (guess where I am from) speaking a different language is that it is the sweet spot of population size, access to the internet and KZbin and the number of poeple understanding English*. Especially people who are interested in things you cover on your channel are very likely to understand enough to watch your channel. Sure, there are countries in Europe where even more people have even better English language skills while not being native speakers, especially when looking towards Scandinavia, but the population of each individual country up there is much smaller than the population of Germany, so they can't get up that high on a list that is surely not adjusted for population size. ;-) And of course, thinking back to the 80s and early 90s, Commodore and Atari were all the rage here. I unfortunately never had any such computer, I wasn't old enough to buy one myself and my parents didn't want to buy one for me. But we got started with PCs pretty early on, so fortunately I did not grew up under a rock. :-) *) Even though Germany are known to often have ze terrible accent when speaking English, zey can still watch your videos.

38:29 - a lot of dual floppy models where used in schools, 1 drive for the OS and the other for student data. I configured a lot of the dual floppy drive models as "wyse" terminals as in dumb serial terminals. Most users preferred them as they had sound & colour (I can still hear that default "eep" sound!)

[@kaitlyn__L]

I had suspected as much, schools ordering that combination. Give a student a floppy for their data and homework and boot the OS off the other one. Maybe even do that at the start of the day and then load in today’s schoolwork software before each lesson? Depending on how scarce the OS floppies were. In the UK the BBC Micros in the ‘80s and early ‘90s had a system for loading the software remotely onto the class’s machines from the teacher’s one, called Econet. But I suppose going round sticking the boot floppy in each machine sequentially might have taken too long, even if only done at the start of the day. So I presume each machine had a boot floppy permanently stationed?

[@projectartichoke]

Riegel sounds almost like 'regal' in English. Although, sometimes the family name is pronounced 'wriggle' in English. Interestingly, the Haribo candy name is a contraction of HAns RIegel BOnn, named for its founder and location in Germany. Riegel literally means 'bar' in German, but it's a specific kind of bar like the bolt of a door locking mechanism. It would seem to be an occupational name associated with locksmithing. And probably where we get the word 'wriggle' like wriggling a key in a lock.

To make a proper C-64 to RS232 interface, you need two of the MAX232 chips. One does the TX/RX work, the second handles hardware flow control lines.

I have had some luck with repairing pcb's that had bad solderjoints. I put them in a oven at 80° Celsius for 10 minutes, let it cool down before handling. You can start at a lower temperature and try increasing the temp incrementally. If you don't have an oven you are willing to use for this you could use your 3d printers heatbed. Best to build a cover to put over the pcb (insulation that one of your viewers uses to pack stuff he sends you) or use an enclosure for your 3d printer.

Re: Dual Drive LC: Yes, they sold loads of them to schools in fact. That way you could keep the OS boot disk in one and the data program disk in the other. In 1990, skipping the hard drive would be a huge cost saving (and a classroom of 30 students loading MS Word from floppy is still faster than a classroom of 30 students loading MS Word over LocalTalk *at the same time*). This would have been especially useful for machines with the Apple IIe card, since the IIe software took up most of a single floppy by itself. About 10 years ago I bought a job-lot of dual-floppy machines liquidated from a school, all with the Apple IIe card. All LC I's have the dual disk ports of the motherboard (but not sure of the LC II and III) regardless of how many were actually installed, and that can be handy since you can connect something like the Big Mess o' Wires Floppy Emu to the other internal floppy port so you've got both physical disks and disk images in one box.

I can also answer your question about the overall speed of the 68020-based LC v the 60830-based LC II. Because both machines only had 16 bit buses despite using 32-bit processors, the LC II’s processor upgrade only provide a modest speed increase over the LC. The LC II though did offer at least one major advantage over the LC it replaced in the it sold for a mere $1300 vs the $2500 of the original, making it one of the cheapest Macs sold at the time. Despite the crippled nature of these machines, Mac users wanting a color Mac on the less expensive side (vs other color Macs) bough enough of them LC and LC II for it to called a success seemingly willing to overlook it hobbled nature. I imagine that most had previously used a monochrome Mac (512k, Plus, SE, SE/30, or Classic) which ran at the same or slower speeds so they didn’t realize what they were missing. If you had “upgraded” from Mac II to an LC then you would have realized that the older Mac II ran at 2x the LC’s speed, despite both having 16mhz 68020 processors because the Mac II had 32 bit bus (though it was not 32 bit clean meaning that without a special special software later developed (MODE32) the bus ran at 24 bit limiting memory to 8mb but still much faster then LC’s 16 bit bus).

The emulators have gotten updates over time, as well.

I would try reflow, hot air until you see solder melting or oven it as could be a ball not connecting

[@Laziter73]

On the C64 Mini board the LED should light up no matter if the SD RAM is faulty. Maybe a power line has gone bad and that causes the problem?

yeah, wouldn't hurt to try. It's best to flood the underside of pbga chips with flux first. maybe a solder joint has cracked.

[@nathanmead140]

The oven doesn't get hot enough to reflow chips so it wouldn't be a permanent fix, it would only work for a little while then crash and not boot again

Those candies are pretty common in Italy too and the country bar (which is just called “cereali” or cereals ) is one of my favorite snacks

Your oscilloscope has built in serial decoding... if it’s not enabled on your unit you can download the code needed. Shortly after releasing the DS1054z they started enabling all the features for free... unless you have an early model, you should already have it there...

The LC does support 640x480 too, at 16 colors IIRC but there's the VRAM socket that enables 256 colors. 512x384 is for the 12" RGB monitor which was a new thing with the LC, and the 640x480 was for the 13" RGB monitor that was used with the Macintosh II models from before. The cheapest monitor was a 12" or 13" monochrome, at 640x480 and 16 grays is perfectly usable with these.

Hi Adrian. I just got an Apple Quadra 605. I'm new at this. I need a special adapter to connect it to a VGA monitor, right? Any tip you can give me in general?

Once you get used to it, reading German is pretty easy. In grad school I had to read a lot of papers in German from the journal Angewandte Chemie, despite the fact that I only speak English. Give it a shot!

[@dolphhandcreme]

BGA soldering actually isn't that difficult - at least in the scale of RAM ICs. Just get a cheap hotair station, flux, some stencils and balls and you're ready to go. Something like a bad ram is a good point to start and learn. My first tries were an old router and a graphics card. I unsoldered the CPU/GPU, reballed it and reattached. Worked both times. You only have to be careful with the desoldering braid and the heat, it's quite easy to rip a pad.

[@nathanmead140]

To fix the commodore 64 mini you could use a digital SMD rework station with the smallest tip, set the temperature to 450° Celsius and air flow to the lowest setting, put the board with the top of the chip up towards you on a cookie pan or a silicone mat (or both), put some flux all over under and on the sides of the chip, hold it with a tweezers to keep it from flying away and move the hot air around it until the solder is melted then turn the temperature down to 375° Celsius and turn the airflow down more too so the tweezers aren't needed to hold the chip without letting the solder harden then give the chip a gentle tap on the sides with the tweezers let the chip pull itself back where it's supposed to be and cool then clean it after it has been cooling for 2 to 6 hours, that should fix it. Or I could probably fix it I would just need to get some more tools first and I don't know how much the shipping would be back west from where I am over in the east.

[@jarrettdoesstuff2318]

IIRC (hey, I was like 7) my elementary school's computer lab was Mac LCs which originally had two floppies. It wasn't much of a problem then because most of the use they got was being booted directly off floppies. I remember them being upgraded to have hard drives later...

Just a tip from someone who's studied German for a few years! an "a" is almost always pronounced as "ah", but the "ä" is pronounced as "ay". So wolfgang would be pronounced more like "volfgahng". German has pretty complicated vowels for english speakers, so i hope i helped you out! :D

[@smeezekitty]

German vowels are at least fairly consistent. English vowels are all over the place.

[@GPSC998]

@@smeezekitty it's what I loved about studying German, the pronunciation was mostly so straightforward (even if challenging at times)

[@CanuckGod]

@@GPSC998 Just have to remember that w is 'v' XD

[@EinKerl3554]

Vowels in German don't have long and short forms, the accents handle the variations. Just say them short (duration) and don't draw them out. The main thing to remember Germans love their consonants so give them emphasis.

@@proCaylak It was originally in support of two of the most ancient Christian national denominations, the Chaldeans and the Syrian Orthodox, who at the time I adopted it as my avatar, looked to be ending 1,985 years of witness in the middle east as their churches and shrines were being blown up, bulldozed, and destroyed by ISIS. The nun was the symbol painted on the door of Christians so that the militias would know who to kill next.

The C64mini is also known as "Retro Games Ltd RGL001" and it is partially documented on linux-sunxi. linux-sunxi documents most of what anyone needs to know about allwinner based devices.

[@d4r1pp43]

Hi Adrian. You should do a reflow of the ram and / or CPU. Some flux and a littlebit of heat. It is already bricked so maybe you can bring new life into the c64mini

There's a "Kinder" candy that's some kind of hazelnut cream wafer stick covered in chocolate, and they're absolutely frickin amazing!

[@tw11tube]

Except for the chocolate covering, it sounds a lot like hanuta, a product by Ferrero which is not (yet?) marketed using their "kinder" branding, although the coloring of the hanuta letters looks like the "kinder" brand in recent editions of hanuta.

[@kaitlyn__L]

@@tw11tube in the uk the product they’re describing was sold as kinder bueno. it was marketed toward an older age range than the kinder surprise and kinder hippos.

I think that case the Odroid was in is for a DS Lite originally, I have one that's practically identical other than it having pink meshy fabric on the outside.

[@jennid8123]

Adrian, you can do a lot with the Odroid. It can have a variety of native software python based. You might have better look with the emulation with different firmware. There are also ways to port Wolfenstien, Spear of Destiny and doom. Also on the other firmware there are ZX Spectrum and C64. Maybe I can't see the lag on the emulators which is scary but I play games I know the speed of that I grew up with on the Odroid and didn't notice and I love the device it is kinda open source and I"m really excited about that microcontroller, I know it's not the best but you can make your own emu box or prorgrams for it. I would suggest getting the extra firmware and retrying maybe that'll help with the problems. You hold B when you power on to change the firmware. If it's not for you no biggie but figured I'd make my suggestions for your enjoyment.

[@jennid8123]

I say all this mainly cause I've had much better luck with esp32 devices than Pis.

[@KamotsTalksTech]

Holding B may not work since that device had the initial ship firmware. He may need to do the hard way upgrade. I have a guide on my channel for it. Also yes it does work much better then how it was working in this video. A lot of other reviewers did the same thing running the old firmware and saying it sucks without trying to upgrade first.

[@heffe2001]

That last candy from the first box looked like a Lindt Lindor truffle to me.. Even down to the fill hole.

[@Charlesb88]

I can explain the second floppy drive slot (for an optional 2nd floppy) on the original LC. In March 1991, around 6 months after after the LC debuted in Oct 1990, Apple began offering a special educational bundle of the computer that came with an Apple IIe emulator card installed in the PDS slot and replaced the hard drive with 2nd floppy drive. The idea here supposedly was that Apple was trying to encourage schools still using aging Apple II family computers to upgrade their systems to a modern Mac that could run all their old Apple II software rather then switching to an IBM PC compatible system instead. Both schools and consumers could also buy the Apple IIe PDS card separately for around $250 for use in any PDS equipt Mac. I imagine that with the much cheaper floppy drive replacing the expensive 40mb hard drive on the cheapest LC, that even with the added cost of the IIe card that this educational bundle was priced competitively enough for schools to discourage enough of them from considering going PC-Compatible.
