Interesting story but true: A few years back, a client of ours had a z80 based mpm based system with three vt100 terminals. SOMETIME AROUND 5:00PM, EACH DAY (give or take a fews mins) the vt100 terminal on the main system blinked a little and the whols system crashed, locking out whatever anyone was doing on the other two as well. They were on a ups, they were on surgr suppressors, the serial cables were clean, eiii specs, we slowd down the baud rate, still happened. guess what: there was a postage meter (read BIG MF MAGNET) on the other side of the wall. 5pm, just before going home, the receptionist whould 'ch-chunk' about 40 letters. -- Michael Scheidell SECNAP Network Security, LLC (561) 368-9561 scheidell@secnap.net http://www.secnap.net > > > > Either I'm missing data showing the crash time, or you didn't > > include it.
