Hi-

Welcome!

I don't have any experience with the nexus card, but I thought that was
a valid way of doing the transfer. Maybe someone else can help?

My VMU2PC program is a bit dated - it was developed under a 366MHz PII
running windows 98. If you've got an old machine similar to this, then
I'd say it's a good way to go. Otherwise, you may have some problems.
The program has some processor-speed specific timing loops, so a 2 GHz
machine will be too fast. (I tried to do it hardware-speed independent,
but I couldn't get the microsecond precision I needed. I could have
done a calibration loop at the beginning (like turbo C does), but I
didn't) Also, Windows 98 is pretty close to DOS - any NT-based OS
probably won't let you play with the hardware at a low level like I do
(I think there is some program that does this; it's probably been
written for PIC programmers). And, NT may mess with the timing some if
it gets a higher-level interrupt.

Even with my original system, the program wasn't perfect. It took some
chicken bones and mystical incantations to get it to work, but once I
got into a groove (something like unplug, plug, then transfer), it was
reliable.

Good luck!

- John
