This computer back in the day was simply a dream machine running at 16mhz on a 32 bit bus. I did own a Mac Se HD back in the day, but gave it up due to the high cost for simply upgrades. My high density floppy drive failed and would cost over $300 Canadian to replace with a trade in of the dead floppy drive while a PC drive was only $30. I still loved that machine.

[@DeathMetalDerf]

While I am quite partial to your longer-form videos, this was still a very satisfying video as well.

Dear Adrian. Some day you'll have to make a video about your t-shirt collection!! They are amazing!!

Adrian your videos helped inspire me after years and years of watching, learning, but not acting to actually try my hand at some of this stuff. I built a mqtt controlled blinds automation system and I've now designed my first board in kicad for a bias lighting setup. Cheers and keep up the good work.

[@csudsuindustries]

Glad you liked the goodies and hopefully will find a home for the system board.

[@Fifury161]

3:18 - yes, 128MB was the maximum supported size, ran it as a web server back in the day. There needs to be some context around 128MB RAM, you have to remember most machines of that era came with 1MB and supported a maximum of 4MB! Even the most expensive PCs topped out @ 32MB and you would struggle to find an OS that supported more than 32MB! We are talking a 25Mhz 486 DX CPU era here!

[@m7hacke]

Hi Adrian, Either format is fine with me. If I can't finish watching one of your videos in one sitting, I just finish it the next day. No big deal. I don't want to put any pressure on you to do more projects in a shorter amount of time. I find your videos entertaining and informative. I learn a lot from you. I usually watch your videos at night before I go to bed. I find them very relaxing. Nice job all around.

I hope you are going to do the analog board - I have an SE/30 with a wonky screen and I’m pretty sure it’s the analog board. This was still interesting - after watching I may need to recap the logic board too. Great content - please keep it up!

I realize the legs will probably pull out of the caps or pull off the solder before the pads come off, especially with the leaking caps, but it doesn't stop me from holding my breath every time you twist away at those caps! Always look forward to your videos and learn a lot from watching them, especially about C64s. Got me started trying to get mine working again.

[@MrDAndersson]

The new format works well, still keeps the vital information that you always provide really good!

[@Echoes_AJ]

Finger contacts on those RAM SIMMs were notorious for oxidation (not gold-plated). Clean them up with an eraser. Alcohol-based cleaners don't seem to do anything. I can't count how many machines I saved just by this simple trick. I've had the same eraser in my toolbox for over 35 years. Some cheap erasers just don't work at all, but the classic pink ones work very well. You can also place a graphics adapter in that SE/30 slot. 8-bit grayscale on those 9' monitors is stunning!

[@Stryder_The_Nite_Owl]

Great video! The SE/30 has a 16MHz 68030 and a 68882 FPU. The paths are 32 bit. The Classic II has the same 16Mhz 68030, and lacks the 68882 FPU (although you can upgrade it to have one). I have a Classic II and an SE/30, and I recently ran Norton System Info 2.0 with its benchmarking program. The Classic II, with its 16 bit data path, scored significantly lower than the SE/30. I don't have the results handy, but I'm building a database of 68k Mac benchmarks.

[@DocNo27]

Also on the RAM, don’t forget the pictures you took at the beginning - if you put them in the way they came out it might just work. Some of those old RAM modules would refuse to work in some slots, but if you shuffled stuff up they would work fine. Always pay attention to what is where if it is working :)

i prefer how the 8 bit guy and lgr do mail videos personally. just going all through the mail, and then setting the in depth stuff for other videos. it can be kinda like a preview of what other videos might be coming up next c: and also, i have adhd, and shorter videos that stay on topic rather than changing to indepth multiple times throughout help me pay attention, even when i use it as something to listen to during tasks (which is a gr8 adhd trick to getting stuff done! unless the task includes reading/writing ofc)

[@Zeem4]

I've got two SE/30s, neither of which I've tried to use for years. One was working with very faint sound, the other booted up to a vertical stripey pattern. That one originally had a motherboard destroyed by a leaking battery, I imported a replacement from the US and it didn't work! I really should take a look at them sometime.

[@AaronNewcomb]

[@jaridcool]

I like this format 4 bit video series... one of the reasons why people send you stuff... they like to see what you can do with the hardware they send you......the faster you get the videos up the better that's my opinion.....plus the longer videos require I have Popcorn available which I don't always have 😂!!!

[@noanyobiseniss7462]

Fun fact: I had a SE I added a 40mb drive to that was so slow to spin up the bios would give the no os frowny face so I had to turn it on and then when i heard the drive spin up quickly turn it off then on to restart the boot process while the drive was up to speed. :) I bought the system to literally play one game and never used for anything else. :)

[@Fifury161]

Another fun fact - I could get a Mac Classic ][ to print a page before the screen warmed up! I do miss CRTs, they seemed a lot more forgiving!

[@isoguy.]

@@Fifury161 shorter vids = more viewer visits = more advertising revenue for the greedy tube. Heck I stopped watching tv due to number of adverts. The tube wants content makers to do 8 minute vids.

[@alextirrellRI]

22:02 - The Mac Classic II and SE/30 are both 16mhz. So I guess the Classic II isn't quite as crippled as we thought. I just lament its lack of PDS slot.

[@wishusknight3009]

BTW Classic II is also 16 mhz.. The biggest difference is the 16 bit vs 32 bit bus. My SE/30 has a Daystar Turbo 040/33 128K on it. (128k L2 at processor clock) which its adaptor slot also gave provision for me to install a Radius Pivot procolor display adapter to hook up its matching 17" monitor. The accelerator sits parallel with the main board while the video card ascends vertically up the side of the case. And yes it was a real pain to install it all. After it all sitting in storage for many years I broke it out a few years ago, replaced the internal drive I had in it with a SD2SCSI card and recapped the whole thing. And it still works as good as the day I got it in 1991. The Daystar and Pivot were installed in late 1993 and really did turn this into a great machine. Before 1993 I still used the orignal 85mb drive with external 105mb drive, external scsi ethernet adaptor and 1x cdrom. And a used HP IICX Scanner for photo restoration work. Such good times. It was all put to bed about 1995 after I got some good upgrades for a power PC I was working with beside it and didn't really get used again until about 3 years ago. The thing I couldn't believe was how much stuff I had crammed on those 2 old drives... Totally crazy. And even crazier was I never had more than 8mb ram in it.

[@HaveYouTriedGuillotines]

An SE/30, now you're speaking my language. This was always an interesting machine to me, a black and white all in one with an 030 in it and much better upgrade potential. Always felt like it was the perfect candidate for some hard modding to turn it into a color Macintosh. Rumor is they wanted it to call it the SEx but they couldn't get the patent. 😂

[@pokepress]

I seem to remember there being some sort of upgrade to get 256-gray graphics on the machine.

Probably not a useful comment, but I basically like everything you do and however you choose to pipe it out to the masses is cool with me. Do whatever makes your life easier.

[@kirbyyasha]

I liked the longer videos. But still liked this too.

[@UpLateGeek]

The SE/30 logic board was designed so that it fit into the SE case, and Apple did offer a service to upgrade your SE, but I believe it wasn't a huge discount. I don't even know if you'd get to keep your old SE logic board, or if the Apple service centre just kept it for spares or something. I also hate those memory slots in the SE/30. Very annoying to remove SIMMs, I think I ended up using a small screwdriver to carefully lever the clips. It's especially annoying because my SE/30 and Classic II are the only working machines I've got that take 30 pin SIMMs, so they're currently my only way of testing my prototype SIMM modules. But not for long! I've ordered an Innoventions Inc. SIMMCHECK PLUS, so I'll be able to test 30 and 72 pin SIMMs! I believe these classic Macs don't use the parity bit at all, so you can use either parity or non-parity memory. I didn't bother with the parity chips on my SIMM prototypes and they worked just fine. Obviously if you have dodgy memory, the machine has no way of knowing and will just crash or fail to boot or whatever. Not sure if the system does much of a memory test at startup, other than checking how much memory is available. Lastly, I believe those video memory chips are dual port chips which are pretty uncommon. The dual port allows the video chip to read the memory independently of the CPU. I've got MT branded Micron chips in my SE/30, and I believe Fairchild also made a compatible model, but I couldn't find any NOS or dodgy Chinese sources for either parts on eBay. I've heard these chips were much more reliable than Micron's old memory, so hopefully we don't see them starting to fail like the Micron memory in C64s. Anyway, another great video as usual. I also like the longer mini mail call videos, but this shorter format is great if it means more videos! Definitely do what works for you though.

[@terosaarela4555]

Nice work! About the caps, I was wondering if it would be safer for the pads, if you held the base of the cap in place with one pair of pliers while twisting the can with another? That way the base protects the pads from the twisting forces. Once the can is loose you can gently lift the base.

[@trumptman]

I owned a Mac Classic II. It was not a 25mhz machine. It had the same 68030 at 16 mhz as the SE/30. However it had the annoying Apple "feature" of running on a 16 bit bus which made the same speed chip about 80% as fast due to that limitation. I also believe it topped out at 10 megs of RAM compared to the 128 meg fully 32 bit SE/30.

[@richardkelsch3640]

Make the mail calls two parts. First part just unbox and show, no going to the bench. The unboxing and the appreciation is enough for one video. Part 2 can be you "benching" what you got on the previous video.

Sweet! I have a Classic II, a regular SE (with 800k drives), and a couple of Pluses. I'm still wanting an SE/30 one of these days... but after I get the Portable up and running... should hopefully know something on that one by next weekend.

It supports the PCM format, there are no parts inside which can wear out over time, runs for months on a set of batteries, their media is dirty cheap and they have a broadcast quality sound. They can be underrated in general but it does much better job than an average Zoom does today. This should have saved it from trash.

When you replace the old SMD electrolytic with tantalums do you derate the tantalums (up the voltage for protection against shorts-fire)

[@benjamincrall8065]

I would probibly disable the speaker amp in the classic psu if you use the se/30 board. Connecting psu ground to the audio input could cause the amp to pull the speaker all the way negative causing it to draw lots of current and get hot. I don't know how those boards work or if they have protection against it, but it would be something to look into if you are using it for long periods.

[@twocvbloke]

Thank you for the awesome video. I have a Mac SE/30 that booted a few years ago but now is giving me the "Simasimac" screen on boot. Any advice on where to start? I've removed all RAM and chips, they looked ok but I didn't use a deoxidizer, haven't washed the board with soapy water yet. I haven't recapped anything yet either or changed the battery. Do I change to a CR3032 like you did, or try to find another like original battery? Where do you buy those caps because my local supplier does not have the same format. Do they have to be tantalum or can I keep with polarized electrolytic? Someone suggested switch to tantalum. NOTE: My original caps are silver cylinders with a gold/yellow band around the base, and a black stripe on the side of the yellow band indicating polarity. Your caps have a black mark on top. I also have a "bodge" wire on the back of the board running from the chip near R29 to the chip near R17. Not sure why, your motherboard didn't seem to have a wire. Any advice would be appreciated. I feel like I'll have to buy some assorted caps from eBay, could I get all 50V rated, and use them even where they ask for 16V caps? There is only one 50V SMD cap needed, the rest are all 16V.

I’m also partial to their Quadra 700 with the 040. Solid build quality and lovely, compact design very similar to the ci. I have two of them , one upgraded with a 100 MHz PPC 601 card, both of which are still going strong three decades after their release

[@rabidbigdog]

@@little_fluffy_clouds That's fair. The Quadra 700 was basically a 040 IIci? I can't remember the memory limits, but my OCD started to trip off when they were promoting machines with 68Mb (not 64Mb) non-powers-of-two. And then of course they abandoned the power-of-two megabyte/gigabyte etc for disk. Basically toy-computers. :)

[@little_fluffy_clouds]

@@rabidbigdog yes, that's the one, it's exactly like a 040 IIci, although with full tantalum capacitors which means there's no need to recap the motherboard (I'm lazy). Design of the chassis is the same, although the placement of the logo assumes it's going to be operated in vertical tower orientation, however it works just fine horizontally, like a IIci, as well. The Quadra 700 got sort of famous after being featured in the original Jurassic Park movie. It can be expanded up to 68 MB RAM, but that's because there's 4 MB built into the motherboard, and you can add up to four sticks of 16 MB RAM on top of that. It's an oddball amount, but I've learned to live with it. It's a generous amount of RAM for classic Mac OS anyway. I like to play my old vintage games on it (Marathon is still fun) and use my old versions of Photoshop, Illustrator and Quark Xpress, just for nostalgia.
