From: Cory Smelosky <b4 at gewt.net> I PROBABLY have a PIC around here somewhere...but I don't know where and I know I DEFINTIELY don't have a crystal of that frequency. Then you just need a longer loop. I have an arduino that I SUPPOSE could be hacked to work. I'm sure it could -- maybe add a 2N7000 or something as the driver since I think it's officialy an open-collector line (although I could be wrong and anyway since it's not shared, it probably doesn't matter much). Does the bus itself need any special configuration? I can't think what this would mean. Just ground the "event" line every 50th/60th and you're golden. The Q22 mod was surprisingly easy too (since there were only four slots, with wire-wrap connectors). If the power supply hadn't later done what all power supplies eventually do, I'd still be running that box... I DO have the front panel with an LTC from the NETCOM I can borrow for awhile (No need for it until I patch ZRQCH0. Yeah bringing it in from another box should be OK as long as everyone agrees about ground reference. John Wilson D Bit
