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 :)

Hi Cindy,

thanks for your reply. I will look them up tomorrow as soon as I have access to 
the boards again.

Cheers,

I asked my DEC dealer friends, and they said the PN will be on the metal 
handles. If you can provide those, then he can tell u what they went to.

Thanks for this hint, Paul. I rechecked for numbers, but couldn't any 
54-numbers on the boards.

Interestingly, the prints in the etches are those I stated and all have an X

I still have not clue what these boards are for. Any help is highly appreciated!

Are the X-numbers stamped on the metal handles? Damn... that rings a
bell... I'm sure I've seen boards from a big DEC system with
four-digit X numbers on the handles but I can't remember which! A big
VAX or something... or was it an 11/70 memory system or something?

Or a KL or KS 10... are they standard hex Unibus size?

Well, I don't know what they are, but a couple of things about that first
board (the one that has the 3 blue Berg headers on it):

It has jumpers for UNIBUS grants (both interrupt, and DMA). Which doesn't
necessarily mean much, the various MK11/etc memory cards (M7984, M8728,
M8750) have them too, and they _definitely_ don't plug into a UNIBUS. But
this card has nothing connected to the CDEF connector pins, but it does to
the AB, suggesting that whatever it is, it might go in a MUD slot?

Someplace I have the pinout for the M9014/etc UNIBUS extenders (cards that
plug into a UNIBUS in/out slot, and convert it to 3 40-pin flat cables), but
I can't find it at the moment (I remember discussing it here, so maybe it's
in the list archives). It would be interesting to see if this card has the
same pinout.

Re: Set of mystery DEC boards: who can help me identifying these?

[Paul Anderson]

the 50x number with the letter behind it could be a dec board number.

The 50 class could be the artwork, and the letter the board rev.  If that
is the case, there is probably a 54- class on the other side of the board
one number higher. The 54  number is the board with components, and can be
tracked down, but not easily.

They could have been renamed by another company.

Any other print in the etch?

Any pictures?
