$15 Apple Mac IIci Recap and Fix

I picked up a clean but non working Apple Macintosh IIci locally for just $15. It had more than one fault so in this video, I go about fixing them including removing all the leaking surface mount electrolytic caps and replacing them with something better.
The computer has an Mobius Speedster 68040 accelerator aka Carrera040 by MiroMac. (Who actually made this?)
Also has a E-Machines NuBus graphics card installed, if you know more about this Portland company or the products it made, let me know.

[@JapanPop]

Oh! One of my favorite Mac systems ever! Had one running FTP in my dorm room, to communicate with my Sun 350. Oh the memories!

[@VictorSilva-rq4kz]

Adrian, I also rework some test equipment that has leaky SM caps and I have found a much quicker and easier way to remove the leaky caps. Simply take wire cutters and grab the collar on the cap and cut off the top. This cuts off the cap top and the connection to the plates. Now grab the remaining piece of cap that's on the plastic base and pull it up gently, it will come off along with the rubber seal. At this point you will have left two remaining pieces of the cap legs soldered to the pads. Very easy to removed with just a regular soldering iron. This removal process takes about 10 seconds and has the advantage of placing very little heat stress on the possibly damaged pads.

[@Geopholus]

Yes, I've seen other videos showing the same process. Thanks for the verification !

We had a IIci in the family growing up and I loved that computer so much. It worked up until the last day I saw it and then it vanished and I never found out where it went. I was really hoping we'd keep it as it was the first computer (aside from the Apple II machines at school) that I got to spend a lot of time with and I really would love to still have it.

[@willierants5880]

Adrian, the most important thing is not necessarily how you did the repair, but that you are actually doing it. It's easy for me or anyone to sit here and critique. Chances are we haven't repaired a darn thing. Well done.

[@jaycee1980]

Tantalums would be OK as power decoupling capacitors, however in the audio circuit they are probably being used for AC coupling. Tants are not really recommended for that task. Still, if it works, go with it. Modern SMD electrolytics arent really prone to leakage like the early ones were. A lot of them had problems with the rubber seals being degraded by the oven reflow process. Not a problem if you fit them by hand with a soldering iron.

[@Geopholus]

I'm an old elec Tech, but just learning how to recap old Mac II's. Thanks for the info.

[@bloeckmoep]

Ah forget that debate regarding tantalums, niobs or electrolytic. Look at a smartphone, no space there so niob and tantalums need to do the same job and honestly they do an acceptable job for those 0.5 watt micro speakers you find built in there. If however your intention is to amp a 500 watt box tower, electrolytic super caps are the way to go.

The cheap stuff yeah, the high-end stuff (what is probably what will still be found in 30yrs) is not glued. I eman, an ip68 smartphone it's, but just apply heat and remove the cover and the rest is screws.

[@SianaGearz]

The glues can be debonded with heat and solvents and reapplied later. This is how it's possible to repair any phone today - though of course not every kind of damage, if corrosion runs too deep, well that sucks. But think about it. Think about the soldering tools you had 20-30 years ago. The high-end rework tools of today, in 20-30 years they'll be no longer suitable for technology that will be available then, so it will be just junk you can pick up. Or there will be better tools you can buy. Those corroded phone PCBs that we keep throwing out? Well it's just not economical today to repair them. If you had to, you could desolder an example board, and then just keep sanding it off to expose all the layers, photograph them, and commission a copy, it's trivially possible today. Automatic population of a complex board is fundamentally possible today with something like a modified 3D printer, and it's likely to get easier for today's boards as time moves on. The high-tech of today will be hobbyist-class tech of tomorrow. Apple started locking down chips to each other to hinder repairs? Well they left a backdoor in that right now only they can use, but i'm sure it will be cracked in due time.

I have an E-machines monitor on a Mac 640. I bought the monitor in '93, I think. It's fixed resolution at 800 by 600. About three months later they came out with the multi-synch version. I had some color video card as well, so I had a dual screen set up. And it was on a ci. So you are bringing back memories. I sold it when I went back to college for my PH. D. I bought a 7500 for the intensive number crunching I needed to do. Kept the monitor, but had to Hotwire it to get the synch off the green. Still worked fine. The e-machines monitor weighs a ton, and still runs. The reds have faded a bit, otherwise fine.

[@Halterung01]

The soft power issues are due to the big axial capacitors on the mainboard. They were on my IIci.

[@hermannschaefer4777]

I had an e-machines monitor and card in my SE. Grayscale, 16" AFAIR, 1024 x something. They normally shipped together, so you bought a 2-page gray scale monitor and the card in one packet. Others were Radius, Rasterops, Megagraphics and Laserview. Z21 was a 21"- monitor, so the card is likely one for that monitor. Costed around $2200-3500...

The only large monitor I could afford was a grayscale one, but with 256 shades of gray it looked nice and was fine for most DTP work I was also doing. Pity I had to sell the Mac to pay for a big car repair during a move to Vancouver. But computers were evolving so fast and PCs were taking market share so much, I guess I would've wound up a faster Win95 PC in a few more years anyway. I cherish the memories though, a truly fine piece of hardware.

10:00 with a hot air station, there's usually no need to pull the cap itself off the board like that first. If you use the hot air to heat one leg/pad then the other, the whole cap (plus legs) should easily lift off the board, too. With many of the pads already corroded, it's even more important to not put any extra stress on them by wiggling the caps. Another method would be to use "soldering tweezers", so you can quickly heat both pads at once without dwelling heat on them for too long. It also helps sometimes to add a bit of flux or even a small amount of new solder before desoldering. ;)

[@shmehfleh3115]

I just recapped one of these suckers myself, a couple of weeks ago. I got it working for a few hours before a Rifa cap blew up in the power supply and stunk up my whole house. I swapped out all the Rifas, but in doing so, I somehow ended up killing the PSU. Fortunately, I have a Performa 600 lying around, and its power supply is compatible with the IIci. I was able to make sure I at least didn't fry the IIci's mainboard, so now I'm waiting for an eBay seller to ship me another Performa 600 PSU. I was lucky I found one for cheap.

[@TzOk]

The preheating of the capacitors have very little sense, it works only with ones which are still sealed. Just add some flux, and use your hot air gun to desolder them. You may also use the soldering iron to lift one side first, and then another. Good idea is to add fresh solder before desoldering a part. When you break the capacitor, you may remove the plastic "tray" before further desoldering of the "legs", there's no point in melting this plastic and inhaling fumes coming out of it.

[@Dxceor2486]

Personally I just clip them off, this has the same effect, then I desolder the legs manually

[@emprsnm9903]

Good man tzok83! Both of those techniques have served me well over the decades (hot air removal, and side-leg when I'm to lazy to get my air gun). The adding solder to corroded and factory solder as well, is very effective for removal. On another topic, why are people so worried over the flux left over afterwards? Just to look pretty? Also, I can't personally recall the last time I lost pads due to heat. Maybe I just don't overapply heat by nature, and that saved me alot of headaches. The only time I lost pads was from mechanical damage, which was the cause of the repairs.

[@pedroneves2701]

The using of Flux it's not for every repair, remember that Flux is abrasive and can lift pads and traces. Sometimes a better soldering station and cutting the legs, not blowing hot air in the caps its the way to do it

[@tombarber8929]

Method I like is take 2 solder irons, one on each side, heating both sides of the cap at once. tends to be pretty easy on the pads

[@SirHackaL0t.]

Adrian Black you mentioned not using force after removing the cap lid but then proceeded to use enough force to lift the motherboard off the table and seemed surprised that some caps came away damaging the pads.

[@4nthonylol]

As for that video Card, you may be able to use it if the frequency is compatible with a current standard and you find out the Po out. If I recall, some mac resolutions were compatible with VGA and some were not. A scan converter might also work with it and adapt it to VGA. If it is monochrome you can connect it to a color monitor assuming the output frequency and resolution are compatible by connecting the monochrome output to the red, green, and blue inputs of the color monitor and you will get a monochrome display on the color monitor.

I transitioned to the flat cells myself, seemed pointless to source way more expensive barrel cells for such an old box (batteries cost more than I bought the old macs for in .. 2006) but .. I still ponder how to invent a nice solution to removing the old holder (or finding an adapter clip) using alligator clips like you have is a bit too kludgy for my taste, but does work in many systems of that era / what I finally figured out in 2019 or 2020 .. when the motherboard battery is dead, there are weird intermittent timing issues that happen, I guess the system keeps trying on occasion to check, and this gives a hiccup to whatever is running. I would have figured that ya don’t really need a battery (for clock), if you are fine setting it each time, or no bothering .. but .. u do (need one).

Mine had a Radius married to a Pivot display (which worked 'ok' but were actually wonky as hell and had a high-failure rate). The system actually retailed for around 6200 in the fall of 1989 - but ya - they were pricey as hell.

I've said this on another channel. I worked in the IT dept at a school in London. We had BBC B, Archimedes, Macs (LCIII & 475's) and PC's. I would bring my Amiga A1200 in (68030 @50 at the time) and run emulators of all the systems on the Amiga (still used Beeb BASIC on the Arch) and while the PC emulation was slow it was usable for what I was doing. However, the other emulators were as fast if not faster than the systems being emulated and that included the Mac. The IT director was a huge Mac fan and one day saw me using my Amiga and asked what I was doing, so I explained that it was easier for me to use the emulators to create work across the systems. I then showed her running Shapeshifter and doing all the same work we used them for then without quitting I jumped to the BBC emulator and ran a program I had done, while the program was running I jumped to the PC emulator and ran a game (Moria maybe?) and just for giggles I jumped back to the Amiga loaded a MOD to play, formatted a floppy and while it was doing that jumped back to the Mac and proceeded to use Pagemaker and an Art package (I think it was Photoshop) the look on her face was priceless she didn't know what to say, she just blubbered something (it was literally incoherent) and left.

To "neutralize" the corrosion wouldn't you 1st you would need to know what the current PH level you are dealing with, otherwise you are not neutralizing anything. Do we really need an acid (vinegar) added to the problem! sure it makes it look good ... that's because it eating in to the surface. Now you have to make sure it didn't get anywhere it wasn't supposed to, like get under another component. Without PH testing it's all best guess, but you can narrow that down with minimal effort. Distilled water & 99% pure IPA are close to PH neutral (keep the air away from them when stored) just apply and mop up with a paper towel (getting rid of the residue) and while they do take longer to clean residue up at least they aren't eating metal hidden away. Using vinegar you probably won't see any problems "probably" after all you are always meticulous with the cleanup aren't you ;-)

Great video! Just some advice on tantalums in general: be careful about their voltage rating! My rule of thumb is: avoid tantalums if possible, otherwise get them with at least twice the voltage rating you would usually use for electrolytics. I think Avx has some great app notes on that topic... if you want to go down that rabbit hole :-)

I have a friend at work that has a old Macintosh he originally had problems getting it working but he said he got it working by leaving it pluged in. I told him its probably the caps and he needs to replace them ASAP. Then he said he didn't want to do that because I think he said he wanted it to be period correct or along the lines of that. I then told him if he doesn't he's just going to destroy the motherboard and if he ever decides to sell it people will probably buy it for parts as the board will be probably be destroyed due to leaky caps. On second thought his problem is probably the power supply which could possibly start a fire if the cap ever explodes.

What would be great for the IIcx, IIci, and Quadra 700 is a second story addon like was made for the PCjr. A plastic frame to fit between the case and lid, with an open 5.25" bay and a couple of 3.5" bays for hard drives. Perhaps have one 3.5" bay open for a Magneto Optical, Zip or other. Could be 3D printed in sections then glued together. prime and smooth the surface then paint to match. Back when I had a IIci with a 60Mhz PPC upgrade, I simply set a second 3.5" half height hard drive on top of the one mounted to the bracket. Was nice of Apple to design these early Macs for full height hard drives. In a IIsi it was possible to use longer NuBus cards in the top slot of a IIci CPU upgrade adapter by installing a half height hard drive so the card could extend forward over the drive.

[@bobz1736]

Love your enthusiasm. You seemed genuinely excited you got it working. Great job 😎

[@brendanhoffmann8402]

I had a Mac ii si when I was growing up. I ended up getting the coprocessor for it. Got it in 1990. Was a good machine but outstayed it’s welcome as we didn’t get another computer until 1997! I was desperate for a powermac but ended up getting a pc instead

We had one of these running a digital audio editing workstation around 1991-92. Running a simple digital EQ on a 5-6 minute clip would literally take a couple hours of post-processing. Insane. I think our CPU was clock rated at 16 MHZ.

[@aegisofhonor]

the iici was Apple's flagship mac for a good couple years till the Quadras came around. the "better" iiFX came out the next year but that was an expensive mess with massive compatibility issues due to it's complicated proprietary design and basically was impossible to expand (you were stuck with what it was forever) where as the iici could be upgraded and was respectably usable for over decade thanks to plenty of expandability even up to 604 power PC by the late 90s.

the switchmode supply is going into protection mode, that's what the clicking is... check the feedback and HF oscillator chopping circuits!

I recently recapped a Macintosh Classic and went with tantalum on the main board as well. The power down message must be standard, as this one runs 7.1 and gives the same message with a fully functional power supply. I use side cutters to behead the caps, but it looks like your method worked without ripping up any pads. Enjoy the Mac!

[@closure4791]

@@adriansdigitalbasement I would stick with hot air. If you get the caps a little hotter they come off in one piece without any force, and no damage to the board as long as it's not too hot.

[@emprsnm9903]

Not necessarily on the power down circuit. I found this that someone who recapped a IIx and had power on/off issues after leaked caps corrosion. It's pretty well written imho. It could help you guys restore that functionality, which mac had a superiority over PC back then (it just worked vs APM on PC not working). www.downtowndougbrown.com/2015/03/explanation-of-the-macintosh-iiiix-power-onoff-circuit/

[@RacerX-]

@Collectorcast, The power down message is standard on Macs that do not support soft power on or off through the Power button on the ADB keyboard. I think there was very few compact Macs that actually supported this. I know the Classic and Classic II do not. Even the 61xx, 71xx and 81xx models do not support soft power on. If the soft power circuit is not working, you will get this message. It could also be a problem with the power supply or the way it is wired if it supports this feature or not.

[@tekvax01]

I feel bad for having one of these, with all the AVID video boards, and then tossing it out in the early 2000s! I had three quadras as well... I think I gave them away to friends!

[@Crashedfiesta]

I'm a strong advocate of replacing like for like. So I would've done new electrolytics - but it's not my Mac. 😁 Nice repair. The only Mac i've done was a Classic II. I put the main board through the dishwasher then re-capped (with electrolytics). 😎

[@CommodoreFan64]

Well then enjoy years down the road having to do this all over again, when the caps start to leak yet again.

I did that to get an old Mac LCII to boot up but since it's PSU is simple I'll probably rebuild the original. I might try converting my IIfx to a coin cells since it's barrel batteries are dead again though I'll make an adapter vs hot melt glue it in.

I had to search for 68EC040. I was familiar with the 68LC040 (my Performa 630CD had that one). According to wikipedia, the EC lacks both the FPU and MMU, while the LC lacks only the FPU. Thanks!

[@youdontneedtoseehisidentif4939]

A black screen but for a dialog stating "it's now safe to turn off this Macintosh" (or words to that effect) and a restart button when it's shut down is normal on Macs that don't support powering on from the keyboard

[@Lilithe]

Yeah. Not a fan of bursting the caps but to be fair to you it won't do much more damage since you're cleaning the site up right away. Instead of "scraping" away the old stuff I'd try to flood it with good solder and maybe use a solder sucker or the wick to pick it up like you did. Definitely some projects for the future like enabling the proper soft-on switch but if you don't care, that's your business! Still nice that you preserved this old machine. Are you going to keep the spinning magneto-rust drive or put a CF card device in there?

[@gmcnewlook]

Off topic but I love that trs badge you stuck on your bench monitor

[@twizz420]

It's a lot easier to remove caps by heating the underside of the board. Conversely, a lot of people just cut off the top of cap and then it just leaves you with the legs, but I find it's unnecessary. Heating from the underside takes just about as long, but much less effort than cutting them up.

[@sonoflysystrata2]

It's been a long time since this video went up, but my wife has a IIci with an E-Machines card and monitor, and probably she still has the original floppies with drivers. Will search them out for you.

[@pauledwards2817]

I have a colour eMachines colour card and the control panel does not do much. It adds the ability to do some colour/brightness settings options and you can create virtual displays which are larger than the monitor can display.

[@luther99flame]

Soldering surface mount components is much easier than what you did. Try leaving one pad free from solder and the component free from solder. Flux the soldered pad, place the component on the soldered pad, heat and slide in place. Then add solder to the other pad and component. Plus you will want to use leaded solder on old boards. Mixing lead free and leaded isn't a good thing.

[@neonhomer]

I got one for ya... An Apple PowerMac 7200 w/ a upgraded CPU Card. It's been sitting on my desk for 10+ years..... last time I messed with it, it did power up and work.

[@The-Weekend-Warrior]

Did you know that the slot on the power button is so you can turn it with a flathead screwdriver. You should check if it's in the position where it actually works. It can be disabled if you turn it sideways. If I remember correctly, the slot should be vertical for it to work normally. I guess if sideways, it should tell the mac to restart if there's a power outage.

[@timb7085]

Just got a chance to view this video. I own a MacIIci (bought new in 1990) - mine has 32MB of RAM with an 8*24 video card. (ci has built in graphics whereas the cx didn't). As for e-machines - I worked with a lot of their video products and while I don't recall that particular card, they were big on both full page and portrait displays. And yes, the greyscale version would have been for a hires DTP FP display. I'm not positive, but I think e-machines also made a pivot display, but I could be wrong. Still, the IIci is an awesome machine. Mine still works (or did, last I tried it)

[@gordonwelcher9598]

These SMD electrolytics are a nightmare. In my designs, I have only used through hole electrolytics until recently. After the problem with the SMD caps, we started to have problems with bad electrolyte in the through holes. I am hoping they have improved. Imagine what would happen if wine bottles were sealed as poorly as these caps.

FYI: For your power button problem, power-on reset is driven by one of audio chips. Not sure about power switch itself. Search google for "Guide to the Macintosh family Hardware", page 272 - there's a schematic of a power circuit. I wonder how HDD died - as at least original Quantum drives (I see non-quantum on video) had problems with bearings and wouldn't spin at all - to get data off them, it was enough to open it and push ("jumpstart") the plates motor so it will overcome initial resistance. This way I was able to dump data of my dead 40mb HDD that came in IIcx. I have IIcx with quite different problem - it won't boot from HDD. Well, it won't detect it on SCSI ID 0. Change SCSI ID, viola - auto-detected under OS7 booted from floppy (but won't boot from it). On ID 0, when OS7 is booted from floppy, partitions are not visible unless it's manually detected by any disk manager. Indeed, some caps have leaked (but not so bad as in yours), that's my next step. As for CMOS battery - those unfortunately DO leak too. I had quite an epic adventure fixing board in Macintosh SE after this kind of battery leaked and corroded almost everything. Here are some restoration images (without comments) imgur.com/a/SOTBvJU and vcfed thread about this journey: www.vcfed.org/forum/showthread.php?64106

[@osgeld]

I had a IIcX back in the late 90's, fun machine, Math processor... basically nothing really used it on the mac outside of excel and a few other dull programs, I installed one on my LC2 it does absolutely nothing unless I am working on the budget, which I don't edit: the bucket mac's do not all have a self shutdown, and just a mains ac switch, so its normal if the machine does the shutdown sequence after the power off signal to show the shutdown screen

[@OTAlucard]

I've got the same Emachines video card somewhere. Been digging into my vintage computer collection lately and selling off the stuff I don't want lately.

[@choppergirl]

I think System 7.5.3 is the highest you can go on the 68040. If the CMOS battery dies on Macs, the whole computer won't boot and will act like it's dead, with no friendly icon warning dialog.

Hi Adrian. Really enjoy your honest and laid-back style videos. I like hearing your train of thought during your repairs and that you include some of the oops moments. Definitely draws me in more.

[@arva1kes]

There is kinda a rule that you don't use tools stronger than the thing you are working on. So using pliers on these capacitors is a bad idea, because you can't feel the strentgh. It's better to use tweezers as they have quite limite strength but still do the job to list parts that are loose enough.

[@idahofur]

I had 2 of those years ago. When people was chucking out older macs all around. I ended up finally with a quadra 650 so if comes with a nice 040 processor. I then added a powerpc 601 card. Plus the model I have did not have the cd-rom kick. No issue on that. Just put another hard drive in it. Then use a external drive. I do admit I wish at that time the drives was ide and not scsi. Since the adapters are still a little pricey. Still trying to figure out if I want to hunt down a nubus video card though. But it plays sim city classic for mac. So I'm good with it.
