Just scored a 128K for $76 bucks on eBay!! Woo hoo!!

That is a neat mod! To be honest, I'd leave it as it is because it seems really unique.

Anyways, congrats!

I kept the board in the 128k position and tucked the switch inside the case. Eventually I'd like to get my hands on a "virgin" board. But for now, it's fine as it functions as a 128.

I got the proper 64kbit DRAM chips from Jameco for under a buck a piece.

Did it at least have the original ROMs in it or were they replaced with Plus ROMs?

Good point. I can't remember if I checked the ROMS. I'll have to look when I get home.

The 128K restoration is complete, except for the external floppy. It starts to boot the machine, I get the "Welcome" message, but then it craps out with a low voltage error. I'll have to check the voltage on the floppy port and see if it's 5V. Hopefully that's all that it is. Other than that, the machine runs great off the internal floppy.

Anyway, it was pretty dirty when I first got it, and a little yellow: (more pics up top)

I dipped everything in some peroxide/oxy:

I cleaned the cables with isopropyl alcohol. The top two were just as bad as the dirty one on the bottom. They shined up pretty well.

The keyboard and mice came out really nice.

All done!

Now, I have a 512K that needs the same TLC........

Damn nice pictures and writeup as usual. It looks fantastic.

Looking forward to the whole set lined up in a pic (128, 512, Plus, SE and Classic) all freshly de-yellowed.

 

[mcdermd]

what kind of peroxide/oxy mix did you use? the only time I've used it on beige plastic, it turned too white.

 

[macman142]

I'm also interested in the cocktail you used to clean it up, don't think I read it on your site?

Thanks. Soon!

I'll be doing the 512K this weekend, then I think I'll be done catching up on restorations. Then I can get back to looking for new goodies!
