From: Werner Uhrig <CMP.WERNER@UTEXAS-20.ARPA> [ I should have thought of posting this earlier, really ... ] Friends, 2 months ago, I hooked up "Micky" to a modem. First, no problem, then, intermittently vertical "snow", then one morning Micky was fuzzy and wouldn't start, screen looked like a blizzard and Micky moaned woefully. After disconnecting the modem-cable, Micky worked fine. Simply connecting the cable to the modem-port caused Micky to "freak out", even with no modem connected to the cable. As I had built the cable myself, I suspected the cable, disconnected the grounded lead to pin 8 - no help. 2 days later, Mickey decided to cooperate again with the modem, however, any time a character came "down the pipe", Micky would generate several horizontal lines of "snow-storm-regions" on the screen. Took it in, they replaced the logic board, Mickey worked ever since (with the same cable and same modem - and I was afraid for a while, that I had screwed up there ...) Moral: exercise the modem port a lot before your warranty is up. PS: why "Mickey" ? use your imagination and you'll get it right.
