Paul, Jerry,
Thanks for the suggestion to take a look at DataTranslation!
Looking in the bitsavers folder for DataTranslation, I found a 239 page
July 1986 Data Translation manual for the DT3362 series of A/Ds. There are 23
sub-models of that board but the DT3362-16SE/8DI specifications
Thanks, I had wondered if some the earlier ADV-11and AAV-11 boards were
just re-branded DTI boards. I have been hoping this is true for the -D
variants.
The most likely candidates are the DT2784/DT2782 and DT2771. Now if I
can just find manuals for these...

I think they were made by Data Translation.

It seems to have two extra CSR registers in addition to the CSR, and read
buffer.

I was thinking that around this time, dual slop detectors were
becoming popular but it is unlikely this is your problem. If reading
a dual slope before conversion is complete, the value read would
be low in value, not just missing LSBs.
They were generally slower as well but often in the 16 or more

I'll second that. The ones I have seen most often (in another industry) were
Harris.
