Maybe there's another option.
As a direct consequence of a careless conversation at an electronics show
a while back, I recently received a copy of Farnell Electronics' catalogue.
(They're on the web, they say, at http://www.farnell.co.uk)
Anyway, they list some interesting devices. Order code 292-849 is an 11-
channel A/D converter that plugs straight into a PC's parallel port. It's
shipped complete with PicoLog and PicoScope software, for which they describe a
variety of logging, oscilloscope and chart recorder functions.
The A/D converter expects 0 -> 2.5v inputs, but voltage dividers are within our
grasp, aren't they? It samples up to 15kHz with a 386DX33.
This thing is GBP95 + VAT. Given that I have had some real wonderful transient
problems to debug recently, the idea of going out on a drive and chart
recording 11 channels of system behaviour is extremely attractive.
