Try 1970.

I worked in the same (computer graphics) lab with Hal. He wrote the
seminal book on microprocessor generated music and later worked at Kurzweil.

I wouldn't want to violate my NDA!

Funny you mention that, I've got a Data Translation DT2766 and it is
identical to the AAV11-C. I mean identical! In the day DT must have
sold them based on 2 selling points: (1) Cheaper than DEC and (2) Exact
drop in replacement for the DEC AAV11-C.

You might try looking for Data Translation products. I know some of the later
ad and da modules were made by them for DEC

The DACs on the AAV11-C board are not marked in any revealing way. I
think they are Burr Brown DAC80, 24 pin, but I'm not sure. I wasn't
sure if they were working and was looking for a replacement.
Looking at the spec sheets DAC's seem to come in Voltage or Current
versions. Life got more
I originally used R-2R DACs but I was lucky enough to be able to buy a
couple of DAC08 chips at Radio Shack and built a circuit using 74LS244
latching buffers so that I could drive both channels of a single 8-bit
parallel port and 2 extra control lines (Select and Strobe).

The Synclavier I was commercially available in 1977, based off the
Dartmouth Digital Synthesizer of earlier times. The core was a New
England Digital minicomputer architecture (they did sell just the
minicomputer to the military, as a side).
The truth is that there were quite a few digital synths
And by 1979 there was the fairlight...

Much the same here. I recounted this on VCFed a few months ago about building a
simple 2-chip 8-bit ladder DAC with
Over the past couple of months I have been working on my FPGA
implementation of the IBM 1410 1960's era pre System/360 system again.
I am pleased to share that the CPU now passes a significant diagnostic,
CU01, which tests almost all of the instructions, and also tests I/O
with overlap and the
