Hi Chris,
I use the Pico Technology ADC100 converter and s/w and find it very
useful.  I only have the DOS s/w which has a really clunky user i/f but
the scope (and FFT spectrum analyser) functions work very well.
The A/D has two independent channels of 12 bit resolution and on my
66MHz 486 samples at up to 110,000 samples/sec.

The sample rate is easily enough for injection pulses which are likely
to be in the range of 1msec to 10msec.

The unit plugs into the parallel port on the pc. WARNING.  It works
perfectly on both of my own machines but it won't work on the parallel
port of my DELL Pentium 166 at work.  (It's a parallel port
configuration problem)

Pico technology have a website but I don't know the URL, it should be
easy to find it.

BTW, your email address keeps changing.  Are you no longer 'Gatesgarth
racing....'?  (Or perhaps you are another Chris Wilson, not the Alpine
enthusiast one!)

Bye,
