cool. Glad you got that working, and thanks for the VID info, that's
interesting.

Where did you get he cypress usb-2*ps2 splitter - if that's what it
was?

I googled but didn't find anything.


note-
Regarding what I wrote earlier about some working and some not working.
I have found out why. It's 'cos USB devices naturally support ps2, so
a simple USb-Ps2 adaptor works. But Ps2 devices don't naturally support
USB. So a little ps2-usb adaptor won't work. You need a beast like
adaptor with special electronics in it. The ones I see are 2*ps2-usb.
For reference to future googlers, these was dealt with in these posts-
