I got everything cleaned up and after a scary session adjusting the horizontal hold near the hot end of the CRT, booted it into CDOS 4.1. The CDP18S801 Floppy Drive System (RCA Cosmac badged but from Pertec) is run off the parallel card of the computer. That seems to make them maybe portable across different systems. I can't do much with the machine however because all the disks that I have for it although bootable, don't have any of the other CDOS files. They all contain what appears to be EPROM dump files. Does anyone have any software for this system? God, I hope so... ;) - Mike: dogas(a)leading.net
