Let's see, how many nanoseconds is that again? (Sorry, I'll go sit in a corner now.)

One (1) user insisted on use of punched cards. This is in pre-ficon days. Unfortunately, the data center did not have the cojones to charge the user. The day he retired, the project was initiated to remove the keypunches and disconnect the 2503(?) card/reader punch. In those days, the limit on bus/tag cables was 200 ft (cumulative). IIRC, that particular block multiplexer was running about 190 ft. De-installing the 2503 saved about 125 ft. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
