Well, my roommate finally got tired of "only" having a Lisa and an Atari ST with GCR for home Macs, 'n' bought an SE/20. Naturally, the Gods of Fate caused it to fail upon startup at home (it's used) and I cracked 'er open. Symptoms are the usual crackling and ticking noises from the power supply on startup, then nothing. Occasionally we got startup, but then the keyboard and the mousk wouldn't move the cursor or do any functions. Aargh. Had to just turn it off (contrary to my every instinct). After a bit of fiddling, we determined that the ADB filter chip is likely the culprit (hot and smelly). Anybody know who makes or where to get? It's by "Tokin", not known to us. This is the newer board with an ADB chip instead of much discrete glue (I sure hope IT'S okay or we're really up a creek). Also, does anyone sell newer IWMs that will eat FDHDs directly? I know that it's the only change necessary to support 'em, but Apple isn't real generous with the upgrade chips (try to get the equivalent of a "Fatter Agnes" out of 'em :-). My first call tomorrow is to Pre-Owned but I thought this an appropriate subject for net bandwidth.
