Thanks to some help from Bob I got past the HP 2117F
power supply issue so
now the box is not totally dead. Some day after I figure out a lot more
about how this system works I'll have to try building an HPIB cable to
connect to the 12821A disc interface in the system and see if I can get it
to talk to one of my CS/80 drives. Apparently this box has a CS/80 boot
prom which I have been told is not too common.
I have a machine with the CS80 boot ROMs but have been unable to dup them.
One of the problems that we've had is finding a burner to dup the ROMs. Bob
Shannon had tried a number of times but still can't get his copies to work.
So... This weekend I wnet to the Melbourne Hamfest and stumbled across an
old programmer that is supposed to burn Harris 7611's. Now If I can just get
Bob to send some of those chips back to me, maybe I can make dups.
See ya,
SteveRob

Steve,
Don't forget to send me the dash number of the 7611 and I'll send you a list of
possible replacement ICs. I'm still trying to find programming info for them.
