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,
