Hello everyone, (cross posting to cctalk/tech)

I've seen a similar message from Matt G. in the past, but I figured I 
would ask again...

I have an AT&T WE 321SB VMEbus single-board computer en-route to me. 
It's sort-of a 3B2/3B5 on a VME card.  It has  WE32100 CPU, WE32106 MAU, 
and a WE32101 MMU all running at 18 MHz.  This seems to put it roughly 
in-between the V2 and V3 3B2 architecture era.  I believe it was 
initially offered by AT&T as a WE32K developer system, but I'm not super 
familiar with it's history.  Once it arrives, I'll of course upload the 
ROM dumps to several archives. The board does not come with an intact 
filesystem or installation media. I am reaching out to see if anyone in 
the community has or knows the whereabouts of any media or documentation 
for the board or UNIX System V/VME software for the WE32K.  I've seen 
references to "WE 321EB Microprocessor Evaluation Board User Manual" 
(AT&T Select Code / Catalog Number: CAT 451-019).  But it also seems to 
be deleted from history.  There is also photos of the install media 
containing:

WE 321SB-VSU Software Utility Programs

VME Device Driver Utilities / VME Dual VSMD-32 SMD Driver

VME Device Driver Utilities / VME Ironics IV-1624 IS-I/O Driver-Source

UNIX System V/VME / Essential Utilities-Disk 2

UNIX System V/VME / Essential Utilities-Disk 2

UNIX System V/VME / Startup Disk

If you can help in any way in preserving another rare WE32K artifact, 
please let me know.

Thanks,

Alan Hightower
