FINALLY FIGURED IT OUT on my system, maybe this will help others. I have 3 parallel devices on my system (Pentium 166 Clone motherboard with award bios.) HP Laserjet 5L, QuickCam, and a parallel Zip Drive. The Quickcam and HP Laserjet will not work on the same parallel port, this is a known problem. I purchased a second parallel port card set up as LPT2 and hooked them up that way. Worked fine. When i got the Zip drive, I ended up purchasing a parallel port switch. The quickcam and printer are never used at the same time, so I hooked it up as follows. LPT1---->Parallel Port A/B Switch--->HP Laser on A, Quickcam on B LPT2---->Zip Drive When the Parallel Port A/B switch is in the "A" position, the hardware clock freezes. When it is in the "B" position, all is well. Problem solved! Cause? Cheap A/B switch? Probably......Not sure... Hope this helps those few folks I've seen with the same problem! Steve
