Our Physics Dept. recently decommissioned their old Bomem Interferometer
computer, which was PDP-11/73 based. Somehow, when it got around to
what to do with it, my name came up. The thing is now sitting in my
cube. The only DEC cards in the box are the CPU and the disk
controller. Everything else appears to be custom.
One of the boards appears to be a custom multiport serial/EGA Video/PC
Keyboard interface that wants the console to be on the PC Keyboard and
EGA monitor. Unfortunately, none of the EGA monitors (NEC JC-1402P3A)
that I got with the system will power-on. You plug them in, flip the
switch, and nothing happens. Not even a power light.
I really have no need for all the custom stuff and would just as soon
remove it as use it. I do have a spare DHV11 here that I could put in
the box, but I do not know if the DHV11 can be used as a standard serial
console.
The DHV11 tech manual does not seem to have any info on using the board
as a console.
Any help would be appreciated.

I think what you really need is a DLV11J. I used one for several years as
my console, and a WQESD/04 as my bootroms.

I'm not sure if the bootstrap will even look for another console
port.
If they have this strange board as their console, they may
be using different boot roms, you you might have to swap
them too.
The CPU card should be almost identical to an 11/83 system.
Main difference is the speed of the clock, iirc.

uhm, i thought a /73 was a dual width card and didn't have any serial or
anything on it. am i confused?

If you have a quad-height card this is true, and the ports on the board are DLV11
compatible. It also has a bootstrap. If you have have a dual-height, you don't have
a console port or a bootstrap.

Nope, the DHV cannot be used as a console interface. If you have a M8192
(same setup I have) then your choices are roughly: DLV11 (I believe either
-E or -F will work; I am currently using M8028), DLV11-J (M8043, a 4 port
interface that uses special connectors; I've used this also), and there may
be a very few others. You need something that responds to the standard
console CSR/vector.
Don't throw the DHV out as that will still be useful for other things, just
not helpful as a console.
