storage. Building a current loop adapter from scratch
might be the
fastest path. I have an ASR33 and a DEC PRS/04 reader (both current
loop, one 110 bps, one faster, IIRC).
I don't know the PRS/04, but if it's modern enough to use TTL ICs (or at
least 5V logic levels), you might be able to find a TTL level serial dta
stream at the input to the curent loop drive stange inside. Tap that off
and feed it to a 1488 (if you have +/-12V available) or a MAX232 (if you
don;'t) and get RS232 that way.
