Hi Bill

I thought that might be the case. I've never written a driver for Windows - I looked into it a long time ago but baulked at the arcane API (compared to UNIX that is). Shame, though some masochist  might take it on. :-)

Incidentally, using Roland's procedure and Ozy I believe that the Last JTAG jumper need not be installed at all if Excalibur is the last card in the chain as that provides the end of line turn-around.

Cheers & 73

We owe  kolja waschk, the author of USB JTAG a bit of thanks for making his code available for the world to use.

This would be a trival amount of work ... don't think we have too many folks on the crew fond of writing Windows device drivers.
