As it turns out, I happen to have an Atari 800 (recently received with all
the trimmings and an original receipt - $2700 in 1981) and a PRS/01 and
a box of paper tapes. What software would you recommend for this task?
How would you get the info off of the Atari once you got in on there? I'm
sure a box of papertape would easily fit on a floppy, but is there an
exchange program so that an 8-bit Atari can read MS-DOS floppies or vice-
versa? Kermit?

Thanks,

P.S. - I also have a passive 20mA converter made by Inmac that I think was
an option for a DECwriter - it has a similar mounting plate and the cable is
about the right length - it would have plugged into an internal 20mA connector
on the DECwriter and provided RS-232 on the other end. I can reverse-engineer
the schematic without too much trouble. It might do the trick as well, but
may require an external 12VDC source.
