alt Hacker NewsI still have my Color Computer I in a box somewhere in the garage, with the original large cassette tape player I used to read and write cassette tapes with. I've probably forgotten exactly what volume I had to keep it at to get it to read the tapes. As a dumb kid, I managed to get the keyboard swapped out (hated the chiclet one it came with), and I think I found someone who swapped out the 16K it came with for (iirc) 128K. I should really see if it boots. Or even turns on.
I don't think the CoCo I could be expanded beyond 32k since that's as many address lines as they brought out to the bus. When I worked for Alpha Products/Colorware, we sold a MacPaint clone for the CoCo2 that required 64k.
CoCo3 came with 128k out the box though.
