However, I now have thought of another way around this
problem. In
addition to the 520ST that I have that needs a floppy drive, I also
have a Mega4 ST that is missing its keyboard and mouse. I see that the
keyboard connector is just a 6 pin RJ12 style connector that probably
just carries serial data. What would be required to make a cable to
connect a serial port on a PC to this connector in order to use
something like Hyperterminal to act as the keyboard for the Mega ST?
Is this simply a matter of making a cable and setting the baud rate
I would assume it is more than just a cable. I would be suprised if the
Atari keyboard port used RS232 levels, I would have guessed at TTL
levels. So you need a buffer chip.
I wonder if you you could make up a cale between the ST's keyboard PCB
(IIRC the keyboard scanning microcontroller is on the keyboard PCB) and
the MegaST keyboard port.
