I just found a PC/AT with monitor and keyboard, but even with all but video card removed I get no POST / ram count. Where do I start first on this type of machine? I also got two PS/2 Model 70s in the same lot, but they both boot into error 161 and 163 but can escape into BASIC just fine. Need to make the config disk to sort them out .... -- Gary G. Sparkes Jr. KB3HAG Error 161 is CMOS battery failure, and Error 163 is Time/Date not set. Replace the CMOS battery, set the date and time, and things will start to straighten out. IIRC, it requires a rectangular battery with 4 connectors on the lead? Mouser still sells these. Cindy
