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,
