Gentlemen,
A little progress thanks to you all (and possibly a setback).
I followed modem7's advice and disconnected the hard drive from the controller card. At start-up with no disk in the floppy and the disconnected hard drive the monitor flashed 701 before going into BASIC.
I did some more searching and found that I had a DOS 2.11 boot disk. I booted from that disk; but, there was a read error on one sector. (I was able to ignore it with no apparent consequences.)
I also found an old boot disk for the Quadram ram upgrade. I stuck it in the floppy drive and powered the system on. The system booted into DOS... the version is 3.1. Not 3.3, but, hopefully good enough to accomplish my goals.
Now for the bad news.
While at the A prompt I attempt to access the hard drive by typing "C:". I get the message "Invalid drive specification". Not really sure if there's still some hope for the data on this drive, or if this is the end of the road. Any advice would be appreciated. (I don't know what's of value on the drive, so I don't think I can justify having it professionally restored (if even possible).)
Thanks,
Jeff
