[comp.sys.mac] High speed Analog D/A on Mac II

wes@obie.UUCP (Barnacle Wes) (02/03/88)

The test lab I work in is looking at moving our analog data
acquisition system from minicomputers (CCC ne Interdata) to micros.
We have been looking at D/A systems for the PC/AT bus ('386 box) and
for the Mac II.

I would definitely prefer to do the programming on the Mac, but we
have not been able to find much in the way of D/A cards for the Mac II
NuBus yet.  Our requirements are for 6 16-bit channels, with a max
speed of 100Khz per channel.  We will not be acquiring all channels at
this speed, but one or two at a time will be required at ~90K.

Also, we need some sort of tape interface for storing the acquired data
on.  We already have several good-quality 9-track drives, does anyone
make an interface board for these for the NuBus?

Any information this newsgroup can provide will be greatly
appreciated.  Reply via mail and I will summarize in another posting.
