"3211" was presumably a typo for 2311, since the 3211 is an impact printer, substantially faster than the 1403 and with a forms control buffer (FCB) instead of a carriage tape.

Excuse me, but what is 3211? I suspect a typo, but I found nothing similar. 2311 is too old IMHO (1964). Maybe 3330-11 ? -- Radoslaw Skorupka (looking for new job) Lodz, Poland ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
