I would like to build a data acquisition system based on a NeXT Cube.
The amount of data to cope with would be something like 4 to 8
channels, sampled at 1 or 2 kHz. Maybe some other application with
fewer channels sampled at 10 or 20 kHz, but not the first time around.
Some kind of data display to be going on simultaneously with the
acquisition, running "forever."
The Software and Peripherals book shows the Dazzl 16-channel A:D, and
the BioTrace 8-channel A:D with simultaneous sample-hold.
So far, I have talked with BioTrace, and with Dazzl's answering
machine.
Does anyone have experience with either of these devices, or know of
any other hardware in this category? Anything suitable that was
intended for the Nu-Bus in the Mac II? Some idea of prices?
I would like to have a system in which the data sampling intervals are
not affected by other CPU activities, like taking a second or so every
30 seconds to sync the disks. "Real time on a Unix-like system" is my
goal, without investing huge amounts of money.
Please e-mail your experiences, if anything much comes back I will
summarize for everybody else's entertainment.
