Yes. I had very brief contact with an ex-PMC employee sometime last
year who said their kit was just the reference design, but I didn't
get any pointers to where said design was to be found - or the fact
the camera wasn't PAL based.

Aye. I booted windows and looked at the quality of the PMC kit output
- it was pretty shoddy (much more so that I remember last time I ran
it with Windows) - magenta and green flickering snowstorm effect. I
guess being stuffed into the bottom of my 'pc junk' box didn't do it
any good even though it was all anti-static bagged.
I've taken your advice and ordered a new camera - actually a USB
based device, listed as working on linux-usb and supposedly capable of
640x480@30fps (Philips PCVC680K Vesta Pro). Not that I ever plan to
run it harder than a few per second for video conferencing.
Thanks for taking the time to fill me in on the pmc camera, Roger.
Cheers,
Mark
