Depending on what you mean by "driver", this
may or may not be an
issue. I use SANE, which I think demands nothing from the OS but the
ability to send SCSI CDBs to the device and get responses (including
data) back. (Of course, adding that capability to an existing OS can
be a nontrivial effort....)
OK... suppose we pick the one machine I use regularly with a bitpmapped
display -- a classic PERQ.
I would have to make a SCSI interface (quit simple).
Write the microcode to drive it (all I/O has to be done from the CPU
microcode). Agian, I think I could manange that
Port the SANE stuff, presumably written in C, to PERQ Pascal, get it to
compile and run. I suspect that is decidedly non-trivvial
Find soem way to store the images and get them off the machien onto
something mroe useful. 8" floppies or DC300 tapes anyone?
