In my earlier video on the overall Apple II line, I showed off my broken IIc that was the first computer I ever owned. Now it's time to sit down and repair it, tearing down the computer and rebuilding it to hopefully be as it was the day I first took it home in 1985. Will I be successful? Spoiler alert: yes. I took the "easy" (though not all that common, nowadays!) way out.
This is another quick video while I work on some more complicated, scripted stuff. But in many ways these are some of the most fun videos to do.
This computer has obviously not been retrobrited - no need to tell me how yellow it is! I may retrobrite eventually but the problem is that it's a temporary solution - the yellowing always comes back after a few years. I'm still deciding if it's even worth the effort.

Just a little addendum - I ended up hanging up my old motherboard on a pegboard, and it gave me the idea to actually frame it. It's nice and square-ish and somewhere around 12" by 10", but it obviously has some depth to it (I'm guessing about 2"). If anyone has any ideas for a frame I can order online that might work for this purpose, let me know.

It’s 2021, Apple llc was my first computer which I still have. A couple months ago I bought the M1 iMac, technology advanced so much which made me think of my first computer, took it out from storage, cleaned it, then fired it up, it started! Only problem is I lost all of my floppies. Now the llc is on the same desk with my new iMac, a family reunion. Thank you for sharing your video.

I had a IIc as a very small child in the mid to late '80s. It has a place of honor on the top of my desk, where it can gaze upon the room full of computers that it helped pave the way for. I haven't booted it up in well over a decade and, frankly, I'm a bit scared to. Thank you for doing this video and giving me some confidence and a bit of motivation to do so. I mean, I still probably won't, because that would involve lugging the thing down from a hutch 7 feet above the ground, but at least I think that I could. Probably.

@ModernClassic 7 лет назад

I was keeping mine in an attic for ten years, which is probably what broke it. But every once in a while I'd take it down to play some games. It's still fun to do that even if it is a bit of work; I think it's worth it. (Now I keep mine in my basement, which despite how it sounds is a step up from my attic. It's at least somewhat climate controlled.)

@theapplechronicles9863 7 лет назад

There's something you should know: The Mac 128k and the IIc used the same RAM chips which are known to fail a lot. You could buy some new ones for approximately 20 bucks and have them professionally installed (requires some soldering unfortunately...) but I'm 90% sure the RAM's to blame here. All those Apple branded RAM chips will fail at some point, so even your 'new' board will ultimately die.

@ModernClassic 7 лет назад

I actually do know - that's why I bought a new board instead of trying to replace the individual chips. With two boards, I now have two boards worth of RAM chips, which should keep me in good supply until I die.

@Purple__ 3 года назад

MT = Micron Technology. Also, your first board has bad RAM almost certainly. Its good to have an upgraded ROM with the built-in RAM testing facility for locating the offending chip. This is exactly how I fixed my own IIc.

A good troubleshooting tip would have been to test the socketed IC's from the old board in the new board to verify their function and marking them as such. If you do decide in the future to have the original board repaired (which would have been my choice!) it will cut down on troubleshooting time and hassle.

The Apple IIc was the computer that got me through college connected to my Hayes 300 baud Smartmodem. I just picked up one from eBay to play around with, since I was not an electronics tinkerer back in my college days, so taking it apart will be my first priority and examining now what I didn't know back then. Great video...Thanks

@alcobufff 2 года назад

Just did this same thing to one of my apple IIc's, bought it in a lot of 2 off of eBay. in may case, while I was getting the apple IIC logo on the screen, I was also seeing a few white marks and it would not read disks even after cleaning the drive head and lubricating the rails. Also like yours, my video as well as power port were not doing so good. Tried to boot using an old but tested disk II drive connected to the motherboard, same thing happened. ended up getting an NOS 1986 rev board off of eBay. In addition to not having the infamous MT ram, I think it had TI ram made in Japan, it has a new type video port and a noticeably newer rom chip. The Install was simple and it brought my broken C back to life.

What a simple set up for the power supply; it just plugs into the logic board. I like modular designs like that.

I have one of these. Still works! Got mine in 1985 when I was turned 16. Awesome times, I was go giddy to have my first computer and it was a really good one with a huge library available. Guess I should start looking for spare parts though because these things die eventually.

@dutchcanuck7550 2 года назад

I had a IIc identical to yours. Had to get rid of it in the early '90s to make room for a new Mac Centris 610. Wish I'd had the room to hang onto it, it would be fun to play with now.

@infinitecanadian 7 лет назад

It isn't the greatest idea to use a drill or electric driver since you could strip the screw holes. My father is a retired electronics repair technician and still does fixes for other people. He _never_ uses anything but hand power for electronics.

@ModernClassic 7 лет назад

Electronics are no different than anything else, and it's no easier to strip a screw hole with an electric screwdriver than a non-electric one. It takes exactly the same amount of torque, which means it's going to put exactly the same amount of force on your hands. An electric screwdriver would literally fly out of your hands before that happened, because you'd never be holding it that tight. You *might* hold a non-powered screwdriver that tight in order to get the rotational torque you need, which actually makes it more likely to strip either the hole or the head. Also, electric screwdrivers are specifically made to have different torque settings. On the lowest setting, which is what I typically use unless I need more, it wouldn't strip the thread off a nail hole, much less a screw hole.

@infinitecanadian 7 лет назад

It's up to you.

@Xilefian 6 лет назад

Seeing him pull out an electric driver get me a short heart attack...A manual you can feel the tension and assess the energy needed as you go. But until something goes wrong, I don't see why someone wouldn't use an electric driver unless they actually encounter these kind of issues - which I have in the past so I now stay away from them.

@wtftastic 6 лет назад

Long shot that anyone sees this that can help me, but I inherited (yes, literally inherited) an Apple 2 with no monitor, but two external drives that had been stored in a damp basement for probably 20+ years. I had diskettes, etc, and am interested in trying to restore the computer but I really have very little know how and am almost certain its FUBAR (the board has what looks like white corrosion and stuff on it). I have built my own modern PC and I can do some very minimal soldering, but am crap outside of that. Where can I find information or even like a guide on how to repair something that screwed up? Or should I give up on it?

@elfenmagix8173 3 года назад

Take the board out and literally wash it in distilled water and dish soap. Then rinse twice with distilled water and then rinse with isopropyl alcohol (high proof of 90% or better.) blow dry with a hot hair dryer. That will clean up the board. Fixing it is a another matter. Check out Adrian's DIgital Basement Apple II repair videos.

Great video, I am going try and a least open, clean and check chips, specifically the IWM which I believe controls the floppy which is not working, the problem I am finding in my research is the chip itself is consider "unobtainium" and the best option is a mother replacement, naturally the first two I find have bad IWM chips.

@RC-74 Год назад

Like you the first computer I ever bought was the Apple IIc. I recently dug it out of boxes in my garage and tried to check it out. Unfortunately I cannot find the power brick or any of the old disks except for Appleworks. Once I figure out how to reconstruct the power supply I'll be giving it a try. Oh, I also have the Apple IIc Technical Reference Manual. If you ever need any info out of it just give me a shout.

@telengardforever7783 Год назад

Whenever I see the Apple //c, I always think of "Ferris Bueller's Day Off", in which he chose to get this computer instead of a car. Funny to think there was a time in which you had to choose between a computer or a car. I made the same decision regarding my first real 486DX2-66. Hell, it was even MORE expensive than a car.

@freeculture 7 лет назад

I also grew up owning one of those, with the matching color monitor (which was bigger than the mono). It is sadly gone, because my family insisted i had to sell it before i could get a new computer. Sometimes i fire an emulator and play some games, i did spent countless hours with that very same Flight Simulator, Wings of Fury, Skyfox, Stellar 7 and many other games. I also had an external 3.5" drive, which was pretty much the same as the IIgs, and the Imagewritter II printer. I only learned about Wozniak after becoming an adult, now i understand things about the Apple //c back then i didn't (such as the floppy noise). All i remember is that noise was music to my ears, especially after seeing a c64 on a friend's computer load a game (eg Skyfox) from a floppy drive... (3secs vs 3 mins?, same game? pff.) All the Apple II lacked was decent sound, and the IIgs cured that, but the Mac was the flagship and the vast majority of software was going elsewhere...

That knocking noise you're hearing when you initiate or the FDD, is the computer sending the "HEAD BACK" command about 40 times. This ensures the head will start at position 0, since the computer doesn't know where the head was left at.

@ModernClassic 7 лет назад

It would be interesting to know but I'm not really sure it's worth the effort. Usually it's bad RAM on IIc's, but it's just a question of knowing which particular chip(s). If the same thing ever happened to the new board, I'd probably just start replacing chips until it was fixed.

@KennethScharf 7 лет назад

Years ago when I worked at Digital Equipment, I built my own LSI-11 computer out of scrap boards I bought from the company's salvage department. (cost me ten cents on the dollar of DEC's cost). I had some bad ram, so I ran a memory test on the board (which means the computer had at least SOME good memory) and then unsoldered the bad chips. I replaced these chips with sockets, and removed memory from another board and slowly placed that memory in the sockets and re-ran the memory tests. Took awhile, but eventually, I had a pile of known good chips which went into the sockets, and a few other boards with bad memory.

I'm planning a series of "is it worth it?" videos on various game and computer systems where I'm going to mostly show a bunch of gameplay, weigh the pros and cons and then tell you if it's worth going out and buying that system, and I'll do one on the Apple II.

@ModernClassic 7 лет назад

No point going on a wild goose chase when I had a whole new motherboard, especially when it's usually the soldered-on RAM chips that go bad in IIc's. I'd also still be left with my video problem in that case. As for the keyboard, it's actually not that dirty - the problem is that the sliders have just gone gritty and the rubber mat underneath has gone stiff. I used this thing for close to 10 years before upgrading and I am a serious typist - this keyboard has a lot of mileage on it. I would love to fix it somehow but I'm sure I'd have to replace at least that rubber mat, and I'd have to make something custom. It also probably just isn't worth the effort, but I'd love it if I found out something that would prove me wrong on that.

There are archives of Apple's old support downloads site which include disk images for GS OS 6. You do need an older mac to actually make the floppies as they're in DiskCopy format, unless you can find a tool that can send the images over a serial connection from a newer computer.

I've been trying to put together an Apple IIc by buying IIc's on eBay that look like they're in need of some work but are fixable. I find the hardest thing is locating IIc's with good keyboards. Do you have any insight on how to tell (by serial numbers, key cap color, etc.) which ones have the good Alps switches vs. those horrible ones with hairpin springs? I'm guessing there is no reliable way other than asking the seller? Do the IIc's even have consistent and decodable serial numbers that might indicate the year of production? Thanks so much. I look forward to your next video.

I'm brand new to Apple, but could it have just been a chip, where you could replace each one from the new board? Does the iic have a dedicated video chip? Really, i'm new to this Apple iic stuff. :-)

@ModernClassic 6 лет назад

It's most likely a bad RAM chip. But there's no reliable way to test those that I know of other than pulling chips out of another board and replacing them until you find the bad one(s). It's not really an efficient way to repair something, and you end up destroying another board anyway.

When I worked on logic board repairs we would have tested chips and parts for ground outs etc and replaced them as necessary. Not replace entire motherboard. So not sure that is how Apple would have done it. Certainly the local computer shop would have not done it this way. To trace the faulty parts would have been a lot cheaper back in the day.

Good video! Thanks. It's good to know that others have the same appreciation for classic hardware, as I do. This was of particular interest to me, as I have the exact same problem with my IIc. Hopefully, I will not have to buy a new motherboard. It was unfortunate (at 13:20) that your hand covered the where you were applying the rubbing alcohol to the drive head. :-( Thanks again.

"0788" date code on your original. I think it's even newer than you thought.

Where does one acquire a working Apple ][ or ][c anyway?

@ModernClassic 7 лет назад

+Nerd Fest Ebay these days :) I have a search result link in the description. Though they were common enough that you can occasionally still find them at garage or estate sales. Or craigslist.

@nerdfest4593 7 лет назад

Thanks! Will be sure to check it out! Any baseline price tips?

@ModernClassic 7 лет назад

Original II's are getting ridiculous, and they're mainly good for collectors anyway (not as capable as later machines). Other II models really depend on condition and completeness. If you want a complete system (at least one drive + matching monitor) in good shape, I'd say: II+: $200 IIe: $250 IIGS: $300 IIc: $250 IIc Plus: $300-$350 (they don't come up that often) You can find any model for less if you can live without a dedicated monitor (use an old TV or something) or you're ok with something in rougher condition.

@nerdfest4593 7 лет назад

OK, thanks! I'm just looking for an ][. :)

@ModernClassic 7 лет назад

An original ][ is going to be the most expensive for a complete system in good shape - they usually start at around $400, and even that seems optimistic these days. Depending on how early a particular system is, they can really go into the thousands. It's gotten pretty crazy. Your best bet might be a garage sale or something, or a bare fixer-upper on Ebay. You can always find the monitors and drives separately and I'll bet you'd pay less for a rough condition ][, fixing it up and then separately building a complete system than you would by just buying a complete system from the start.

Man. You dont replace a whole motherboard or keyboard. You fix it. That replacement board is a time bomb as well. Start by cleaning the thing in alcohol and then look for caps leaking out. Text for continuity. Look for board crack running through the traces etc.

@ModernClassic 4 года назад

Done, done and done. Didn't find anything; replaced motherboard. Easy and works.

hi, did you know that you are Jim Kuback from the animated show Mission Hill? thought i would let you know in case no one ever told you before!

@GORF_EMPIRE 4 года назад

Why not flip a few chips from the working mother board? Why just give up and replace the mother board when you can try to see if it's one of the socketed parts? Most of those chips are off the shelf and you can have two working MB's and even sell one to get your money back. Friendly word of advice. Invest in a multimeter and an oscilloscope. They are not hard to use and you could learn a few things about how computers work on a low level understanding.

Where do you get that motherboard? I need a new one for my Apple IIc too.

@laurensnieuwland4657 7 лет назад

have you tried to bake the mobo?

@evknucklehead 6 лет назад

That probably wouldn't help as there really aren't any surface-mount chips on this model.

How much would you say these go for? I have an old Apple IIc Computer w/Monitor, cables, and an extra floppy drive. It's all in reasonable condition, the serial code and manufacture date are all visible. But when I hook up the monitor, and kick on the computer, I get your average 'Apple //c' text, and a couple stray letters. I know that's not normal, but everything still works. I'm trying to save up a little for a new PC, and I'm trying to sell some antiques, and I wanted to know how much these go for?

@ModernClassic 6 лет назад

The IIc is the cheapest of all the II models. With the monitor (I'm assuming you have the monochrome one like mine), cables and extra floppy, maybe $250 or $300 if it's in really nice condition.

@gang_stalker_ 6 лет назад

Alright, thanks! I was hoping it would be a bit higher, $250 is still a good start though! Thanks.
