Hi
I just acquired a Philips P2000C. This is a luggable CP/M machine with a dinky 9" screen and twin Teac FD55 drives (DSDD 640k). However, it is not working. At boot up it shows a random pattern of graphics characters. I say random, but it is always the same pattern each time I boot, so not like a PET boot screen.
The machine has a CPU board with a separate "terminal" board that is connected to the CPU board via a TTL level serial link, so the display looks like a dumb terminal to the computer.
According to the technical manual, the machine waits until the terminal board sends two characters. Only then will it proceed to boot.
So I'm thinking the terminal board is suspect. Does anyone have any clues on how to proceed?
