About a decade ago, I bought an old, neglected and very yellowed original Macintosh from Craig's List for $20. Inside was a Macintosh Plus logic board, but since the back panel had not been modified, the computer would not even close correctly. The analog board worked, but I wasn't going to modify the case to fit the logic board. I have been waiting for a long time to find a 128K logic board to properly fit inside of it.
I got lucky on ebay a few weeks ago and scored a Macintosh 128K logic board with a RAM and SCSI upgrade, as well as a 800k drive and the Mac Plus bracket for the drive. It was advertised as a "Vintage CPU Design Apple Macintosh 128k to Mac Plus motherboard upgrade kit." $75, including shipping from Canada, seemed like a good deal, since I have struggled to get anybody to let go of one for less than $100.
The board arrived about week ago and had the brand "CPU Design" on it. I screwed everything together, and it booted right up. It had 2.5 MB RAM, SCSI, and newer ROMs. The old Mac finally lives!
