A/D and D/A conversion for ULTRIX-32

[Lars Svensson]

We're considering equipping our recently installed VAX 11/750 (running
ULTRIX-32, which is supposed to be 4.2) with A/D/A converters to be able to
test some speech encoding algorithms. An estimate of the resolution needed
is 12-14 bits, and we must be able to sample at 8 kHz.  (These figures are
the minimum requirements.) Using a timeshared machine such as ours for
real-time work such as sampling should be asking for trouble, I guess;
however, I've seen a thing like this running on a VMS machine. 

My question is obvioius: Is there anybody out there who has had any
experience with a setup like this?  All kinds of information is of interest:
preferred hardware, the existence of any kind of software support,
price and performance of the running system etc.

Please respond by uucp mail to the address below. If there is any interest,
I'll summarize and post/mail.
