I'm in the middle of working out the pinout for the power supply connector
on the MDP-1000. I'm aided somewhat by a set of test points on the
backplane, unfortunately the "+" and "-" symbols (in the solder mask labels
next to the test points) are nearly indiscernible, so I'm trying to verify

This is a long shot, but I was curious if anyone might have information on

I'm working on a PDP-8/A I picked up at VCF West last summer. After a lot

Subject line says it all. The Lambda uses this as its disk controller and
it's looking like the one in mine needs some debugging. There doesn't seem
to be any documentation for this controller out there. There are docs for

Curious if anyone has a spare L0022 memory controller, this allows a
VAX-11/750 to address up to a whopping 14mb of memory (2x4mb, 6x 1mb

the memory controller to be able to use them...

I'm working on implementing an MSCP controller on top of Joerg Hoppe's
Unibone and I'm making pretty good progress -- RT-11 works and I'm working
on getting 2.11bsd to boot from it in an 11/84 (it works well enough to
load "boot" which then loads the kernel, then things fall over).
However, given

Hey all --
Trying to track down technical info for a Dilog DQ100 controller. This is
a QBus controller compatible with the RK11 (or RKV11, in this case) that
works with various RK05-compatible drives. (See the brochure here:

Hi all --
I picked up a Sanders 720 terminal -- well, the display/keyboard portion
anyway -- and I'm looking for actual hardware documentation so I can maybe
someday replicate the 701 control unit (or heck, maybe someone has a 701
sitting around somewhere...). Anyone out there have docs (apart

Hi all --
Anyone happen to have any documentation for the Andromeda VDC-11? This is
a dual-height qbus board that provides 512x256 graphics and can act as the
PDP-11's console device (it emulates various different terminals, depending
on the model of the VDC-11). I'm interested in programming

Hi All --
Thought you folks might be interested -- I've been working on a Xerox
Star emulator at LCM+L on and off over the past year and I've finally
unleashed it upon the world. It's called Darkstar, it's open source and
it runs all the Star software I'm aware of. The Ethernet interface is

Nope. This card expects pre common command set disks with non-embedded

Hey All --
Picked up a nice AT 630 MTG terminal, sans keyboard as so many terminals
are these days. Curious if anyone out there might have one available. You
can see a picture of one here:
http://bitsavers.org/pdf/att/630_mtg/630_MTG_Brochure_1987.pdf. I believe
the part number to be 33401 or
101 - 200 of 316 matches
