Here's the task facing our Physiotherapy School:

One the one side, they've got an 8Mhz PC-XT.
And on the other, there's a host of sensors, microswitches
and other devices (such as an EMG) producing low-voltage
analogue signals.

They would like to have the PC capture these various outputs
(there are six in all) so as to facilitate analysis; at the moment,
they use an array of storage display scopes (with cameras) and a
chart recorder.

It looks like a multi-channel analogue-to-digital converter (ADC)
fitted to the PC might do the job.  Eight-bit resolution would do,
and the device would have to have a sampling frequency of about
10 Khz (for all of six channels).

Has anyone gone this route already, or even done something remotely
similar?  If so, I'd be very glad to hear of it, or of any source
of solutions to this task.

Many thanks.
