There is at least one manufacturer of a RS-232 to IEEE-488 converter (I do have literature around here somewhere). There are also IEEE-422 boards to plug into a UNIBUS, QBUS, MULTIBUS, ... --- UNIBUS, QBUS are trademarks of DEC, MULTIBUS is a trademark of Intel -- Ken Turkowski @ CADLINC, Palo Alto, CA UUCP: {amd,decwrl,flairvax,nsc}!turtlevax!ken ARPA: turtlevax!ken@DECWRL.ARPA
