Hi Sean.
--- snip ---
1. Does anyone have the pinouts for the serial line
connector
on the DL11 board?
I can check at home. My 11/34A console is connected by a self-made
connector. Just a few wires. Which DL11 board do you have?
M7800, M7800-YA or M7856?
AFAIK, the M7856 is most common.
2. Does anyone know what that BM873-YJ board is?
I'm just curious.
My guess it is an M873 variant.
In that case it possibly contains boot ROMs.
3. What would be the best way to get this old system
running
again? I've got no interface to that RX02 drive, and even ....
I would opt for:
- an RX02 with the M8256
- an RL02 with the M7762
I remember someone asking about loading software over
a serial line?
Sorry. No experience with that.
I will report back tomorrow, as promised, unless somebody else already
told how to connect the console.

PS. You may find some info on the 11/34(A) on my website.
Click on the 11/35 console.

a serial line?
Thinking I had on the subject is that it would be trivial,
given the 11's console abilities (set address, deposit byte)
to take machine code and have a PC program turn it into a
stream of Deposit instructions, heck it could be a 'vi' macro.
There may be a need to control feed speed, but I'd just try
dialing the baud rate down for starters.

If you only need to push some bootstrap into the machine, a terminal
emulator like kermit(1) or minicom(1) with a script (sed(1) is your
friend) will work well.

This was basically the idea behind a device which DEC was working on
for field service, but never released -- the TechMate. It was an
11/2, TU58-based system built into a suitcase which would be used
to download test programs to an -11 or uVax via the console
line...
I believe it was killed because it was too heavy (about 30 lbs)...
I have one of the protos. (I'll be bringing it to the VCF/east)

I guess the somewhat successful Osborne and others of its ilk didn't
impress them?
