Shoot, well, talking to myself. I found this on a German page (also I was trying an LPRINT to test, which was suggested on this forum somewhere):
- Error 140 (frame bit error) means that something is wrong with the expected stop or start bit. The error can occur when the data transfer speed does not match the expected one. However, it can also occur in the event of a short circuit on the data line (Atari Computer: D_IN), in which case the expected stop bit never comes. If you boot an Atari while D_IN is pulled to ground, you can hear a significantly different SIO noise than when no device is connected
As a result, there might be something wrong with the replacement CPU.
Did you actually have to load an ATR8000 driver to use drives and printers on the ATR8000? I mean no ...
Have you ever connected a floppy disk drive to the ATR8000 and tested disk access?
I also can't get the tape drive to work (newer 410, so far replaced the 4 belts). I have a box full of childhood tapes and 4 holders of floppies, so part of me just really wants to see my childhood. I'm trying to get this working so I can give it to my brother / nephews for another generation to enjoy. I am unexpectedly seeing him soon so trying to get this done in the next two weeks which seems futile at the moment.
Anyway, back to the floppies -- I'll try sticking one in but I'm afraid it might eat it or something. The floppy drives are making all sorts of crazy sounds.
