Hello all,
I recently got a bunch of boards from somebody who was
either not able to tell me where they were from.
The boards seem to be unibus-based with numbers starting with X. I neither came across
these before, nor could find any information in the web about it:
Type, P/N , Description
X029, 5013132B, AUC interconnect
X022, 5012197C, unibuswindow
X021, 5012181C, CD ROM control (did that ever exist for unibus?)
X020, 5012180B, data path
Two 16K mos memory modules M7847 came with the set.
Thanks to everybody who tried to help figuring out from what installation these DEC boards
with Unibus-type connecction are. I'm somehow amazed that there seem to be some board
types from DEC around that seem pretty much unknown. I also didn't find any
information in the DEC part number catalogs on bitsavers. I confirm that the X-type
numbers (x020, X029 etc) are found on the metal etches of the boards.
Anyway, I will keep the photos of the boards at the below link. Maybe somebody who steps
over it someday can tell us what these boards are from :)

Thanks again to the list for your help so far on this,
