Yes, I had noticed that they are very, very similar. In fact the system
(see more below) that contains all of these DT boards, also contains
a real KWV11. Why the system needs both is also a mystery to me...

You both may be interested in having a look at the system that these
boards all came in. It is a Data Translations LAB DATAX box with an
H9275A backplane and, by the time I got it, an LSI-11/2 CPU.
The front panel is really also the rear panel. There is a DLV11-J with
four serial lines brougth to 9-pin D connectors, and some BNC-type
connectors for signals in and out from the box. What kind of software
goes with it I don't know, but I do see the system auto-booting to some
roms on the DT3382-8DI board (I think) and I wonder if just starts
processing when powered up. Don't know for sure. There is a label
on the underside of the top cover that I believe represents the original
configuration when it came out of DT:
1- KDF11 & KEF11AA | D4 Interface
2- DLV-11-J (177560) | 256KB Memory
3- LDT3382-DI (771420) ->
4- LDT2768 (167770) | LDT3371 (771140 / 420)
5- LDT2769 (170420) | (empty)
6- (empty) | (empty)
7- (empty) | (empty)
8- (empty) | (empty)
9- KPV-11-A (177546) | (empty)
I have no idea what the 'D4 Interface' is. It's no longer in the box.
I've added a couple of images of the box to my Mystery Boards
webpage:

I'd not mind getting my grubby paws on those
Data Translation
boards if you or J want to unload them, maybe some swappage or
something. I do lots of related hacking and would likely pop for the
$50 for the docs before too long so they can be used. (and get them
to Al of course)
Thanks for the interest. For now, though, I think I'll hang on to this DT
gear since it looks to be a 'system'. Perhaps I should spring for the
$50 doc set. How long ago did you make your inquiry to DT?

He was rather hilarious in many of their ads...that
always gave me
a laugh.
Oh...ahhh...before my time, I guess. I must have missed that 'show'.
