Hello list,
I've recently acquired a PDP-11/04 which in its past life was the controller of a CNC precision drill/router (not the network kind) system. Inside which have 2 boards (Unibus of course) described as below:
First clue: Upper left hand corner says it's from "Advanced Controls Corp.". A quick search points to
http://www.acsmotion.com as they seem to be in the same field, industrial/machine controls. Alas, their tech support doesn't even have a clue as to what a Unibus is...
Both boards appear to be the same model/type, but one is a earlier revision with a lot of reworks; i.e. jumpers and 2 smaller daughterboards, of which the later revision board doesn't have.
Each board have 2 BERG-like male connectors (50-pin and 40-pin) which (guessing here) connects to the actual drill/router itself.
The board is made out of SSI/MSI/LSI TTL ICs. The most complex/prominent are the two 12bit Analog Devices DACs from the DAC80 variety, both made in the late 80s:
DAC #1
- ADDAC80N (24-pin)
- CBI-V
- 8802
DAC #2
- ADDAC80D (24-pin)
- CBI-V
- 8811
I guess these are for the X-Y positioning, but of course I may be WAY out here..
Board #1
- S/N 11926 (sticker)
- P/N 18992-103R (scribbled on handle)
On the upper left hand corner:
- Advanced Controls Corp.
- PCB Detail No. 17795 Rev. H
- ASSY No. 18992 Rev.
- Replaces 17750
Board #2
- S/N 0000005077 (sticker)
- P/N 18992-102R (scribbled on handle)
On the upper left hand corner:
- Advanced Controls Corp.
- PCB Detail No. 17795 Rev. D
- ASSY No. 17750 Rev.
If anybody can positive ID these boards, it'd be great!
If anybody has the programming docs for these, it'll be even greater! :-)

p.s. These boards seems to have last tested OK on Oct 28, 2002 (from a "tested" sticker)!
