I thought this list was about classic computers, of which collecting is a part. I am not interested (well, not as much) in the "hows and whys". I want to find them, use them, fix them. I don't really collect them simply to collect. You might argue that I had to collect one to use it, but thats not necessarily the case. I could have bought my Kaypro new and simply still be using it. If this list IS about COLLECTING, then I will unsubscribe myself as well. On something more hardware related, I have a Radio Shack TRS-80 Color Computer Controller, Cat. No 26-3129. I am assuming it is a disk controller, but can someone give me some confirmation on that? Also, if someone still needs the definicon board stuff, I finally got my PC back together, so I can read the 5.25" disks. And while I am babbling, not really classic computer, but classic test equipment related, I have a Simpson 303 that I have never been able to get to work. It seems to need the battery, and it is a rechargeable model. Kelly
