I took the approach of writing a program for the PDP-8 to dump the
data out the serial port so I could capture (and restore) the disk images
on a PC. If you have an pdp-8 the program dumps the floppies in 8 bit
mode so 11 floppies will be correctly dumped also.

I haven't spent too much time looking at the interface but most of the
smarts are in the drive and serial communication is used to send
commands to it. I have a bunch of information on the RX01, the RX02 should
be similar.

Or if that excessivly long link doesn't work search for rx0 at
http://www.pdp8.net/pdp8cgi/query_docs/query.pl

If you need more I can see if I have more information I haven't scanned,
email me with what you are needing.

The cable I made to hook my 8 to the DB25 on the RX02 has 22 wires in it, I
don't remember how many are grounds.
