Forgot to mention that I have tried switching out the ROMS with known good ones to no avail.

Howdy, I acquired a Mac 512k with a Levco MonsterMac/SCSI upgrade. After fiddling with it a bit I got the RAM working (2mb total) and the external SCSI working (booting to 6.08). The internal SCSI did not work, I think because the cable was/is damaged at the connector. After deciding to...

Thanks Kai! Being the long time computer guy that I am, I dove right in to the simple method. No need to backup. I know all about computers. Well, if you choose a resolution that your poor little Cirrus chip doesn't support, guess what? Windows won't boot, and since I was so smart and didn't...
