Jerome Fine replies:
I presume from what you are saying that the Viking/QDT does not have any
boot ROMs. If so, it is one of the very few (probably the only one I know
about) NON-DEC controllers or host adapters that does not have a boot
ROM.
Any idea if there was a DEC approved CDROM drive which did NOT
use a caddy?

Any idea how much an M8190-BB (quad 11/73) might cost? I have a
couple, but I want to keep them for a few more years. But Tom might
find this is the least expensive way to go.
Sincerely yours,
