Well, if I can get the new CPU on, and I can manually set the bus to CPU ratio, I wont have to stress the support chips. Of course, the PC may not handle supplying a 166 MHz 603e (I figure I would clock up to 166 and not push it too hard). As soon as I get my nerve up..... I dont have a PACE station (although I have friends with them), but I do have a good iron. I just wonder if its good enough...... Mad Dog ---------- Duo/2400 List, The friendliest place on the Net!
