I've got an embeded syatem based around an LSI-11/2
processor board,
M8044-BB (8KW?) memory, pair of DRV-11's, a MDB eprom board and ADC
board. What do I need to do to make this into a functional PDP-11? I've
got a DEC MSCP ESDI controller (don't remeber the part #), DLV-11 (8-port
version) serial card, TQK50, and drives from my VAXstation 3200 I can
try to use in it. It's from my DPE 5000, the video part of which let out
a bunch of magic smoke being powered on - can't find any obvious burned
parts, but haven't checked the power supply yet. Still, it's worth more
to me as a LSI(PDP)-11 than a video effects box that I can't fix.
You haven't mentioned what kind of backplane it has (Q/Q vs. Q/CD),
whether it has 22-bit (I suspect just 18-bit) and how many slots.
These will all affect what the suggestions.
Going with what you have, I might suggest upping the power from
an 11/2 to an 11/73 (KDJ11-A), which takes up no more room in the
backplane.
First, however, I'm sure I need DEC boot roms for
it, or some other way
to get boot code into it. Does anyone happen to have some laying around
they could maybe send me an image of? Also, I'm on the lookout for a
RLV12 and berg cable to connect to the RL02 I have sitting around here..
I would suggest an MXV11-B, which gives you two serial lines, memory
and boot code in one dual-high board. Beyond that, the DEC MSCP board
is probably an RQDX(3?) and is not ESDI (I don't think there was an
ESDI board made by DEC... all the ones I got while inside DEC were
made by Andromeda -- the ESDC board). Finally, a DELQA for network
and you're all set.
