I've got a couple of 128c's, and the first one I got would SOMETIMES load stuff and would crash into the monitor every once in a while. In addition, when trying to use TWO 1571's in GEOS, the software wouldn't load...however if I used a 1571 and a 1541, it would work okay, or if I simply turned off the extra 1571. The other 128 console works perfectly with the same drives. I figured that maybe there might be an incompatibility between the combination of drives I was using, so I used a third 1571 in various combinations with the other two, but that didn't help. Oh course the funky 128 console will reset randomly for no apparent reason too. Not sure if it's related to the power supply yet (which is quite likely), but like I said, any combination of drives on the other 128 work perfectly. *Geoff!* - This message was sent through the cbm-hackers mailing list.
