128k Mac

[waynestewart]

I picked up another 128k Mac, this one from the 29th week of 1984. It was in good cosmetic shape but wouldn't boot and gave an odd error code. I guessed that it was more than one bad RAM chip. On examining the motherboard I found a badly done chip replacement. I took care of that but that wasn't the problem. Bad workmanship just bothers me sometimes. Replaced two RAM chips and it started asking for a floppy. Connected the floppy drive back up and was getting clicking sounds and the drive wasn't reading. Cleaned the limit switch. Now it's booting fine.

I picked this up cheap with the idea of repairing it and selling it. I've never done any selling. Maybe I'll try my local craigslist first. If that doesn't work then I guess I'll have to get paypal and try ebay.

That's a good find and good work fixing it. Why not try selling it here?

Cool find and nice work getting it booting! I second the idea of listing it here first.

where did you get ram to replace from? CL is good, generally someone interested in this item should be safe, but ya never know... it seems to me people on this site are pretty awesome, you could try here... One thing with ebay, if you want big money, ( if you decide to go that route ) Clean it up as best as you can, so it visually looks good, Take pics of it, Take pics of it working, Heck if you feel like making a small Youtube vid and embedding it into the ad, that will help, try to include a Keyboard and mouse, and a Boot Disk, and some games, that way its a complete unit... no reason you wouldn't get tons of bucks for it! 128k's are going for a really healthy amount right now!

The RAM can be cannibalised from a 512K board - it is higher density RAM, but the 128K only sees what it wants.

That's how I fixed mine

4164s (that's what the 128k takes, isn't it?) aren't exactly that difficult to find. Jameco has them as pulls for 99 cents each.

I was going to say, I think I bought mine for under a buck a piece at Jameco.

The RAM came from an Apple II printer buffer card. I didn't want to accidently solder in bad RAM so I used the Applied Engineerings utilities to test it in a Ramworks in a IIe.

It came with the wrong keyboard but I have a number of the correct ones somewhere. Also have a couple of those plastic accessory boxes that it would have originally come with. I should have a bunch of 400k disks around somewhere. Just can't seem to locate them at the moment. I thought they'd be with an older 128k I have but that doesn't seem to be the case. Probably be a month or two before i get everything together. I'm a little busy at the moment.
