I also have DT2769, DT3371 and DT3382 boards without documentation. I
emailed Data Translation for any support information and they didn't
have any "at hand", but would get me copies from their archives for a
service charge of US$50 or something. Since I didn't really have any use
for them, whatever they were, I passed.
The DT2769 is a KWV11-C Programmable Real-Time Clock. If you look in the
Micro/PDP-11 Handbook page 214, the boards are essentially identical.
The analog hybrid (?) block on the DT3382 is the same as that on the
ADV11. The DC006 and DC010 chips indicate that it does DMA.
Never figured out the DT3371 either. It has two analog outputs though.
:-) It also does DMA (DC006 and DC010 again).
Didn't Data Translation always have the company presidents face in every
advertisement? I can see the face, but don't remember the name...
[Google for it] Fred Molinari.
