I got the 486 machine today. I had to replace the 80GB hard drive and put a 5.25" floppy in it since it came with only one 3.5".
I removed the tape drive to make room for the 5.25" floppy. I didn't have any software for the tape drive anyway. So I have the 5.25" as drive a: and the 3.5" as drive b:. I formatted the hard drive and loaded in DOS 6.22. I also replaced the battery on the motherboard of course. Everything seemed to go well and I was finally able to get my Clipper 5.0 installed on the hard drive. Yippeeee!
I still have to figure out what the problem is with the 80286 though. It can't be the floppy drive because the new 5.25" floppy that I tried in the 286 and would not read is the same 5.25" floppy that I just installed in the 486 and it works perfectly there so there has to be something else going on. I am waiting on another FDD controller and I'll see if it makes any difference.
The 486 has a modem card installed but I don't know what the baud rate is. I'm guessing 1200 but I couldn't see anything on the card itself to indicate the speed. There were a couple of extra modem cards in the box as well. So now I can finally do some Clipper programming.
