Hi,

one way of doing this would be the use of a TU-58 tape drive. This device is
internalley using a disc-like structure, and it will connect to any serial port.

There should be a PDP8 OS8 driver for this. And with the RS-232 interface, this
could be used for any other computer as well.

The real TU58 is sweet, but terribly slow. On top of that, the tapes are
expensive. But there are cool alternatives:

You will find a semiconductor-emulated TU58 kit on:

Also there is a PC-Emulation on:
http://www.not-compatible.org/PDP-11/programs/tu58sim.html

I havn't yet used any of these, (have a real TU58), so see for yourself how
useful this is in your system. Please post the results!
