The last email response i got from Jens said he would not be developing Vista 64 Bit Drivers.

Jens was speaking about *64 bit drivers*, so I am quite sure the current Catweasel drivers for XP 32 bit will still work with Vista or Windows 7. If they do not and Jens is not going to publish newer drivers (which I don't really suspect), then you can still use the Catweasel on Linux. My CW MK3 runs fine on Debian Linux with Kernel 2.6.30 and drivers from here:
http://llg.cubic.org/cw/ (the patch to work with recent kernels was done by a friend of mine

). On Linux you can use your catweasel on any computer which runs Linux and has a PCI-bus (Alpha, Amiga, Apple, Intel 32/64 bit, etc). There is also a separate driver called "catweasel" to use the SID and the joystick-ports.
