As mentioned here before, I've had really good results with a cheap USB-Serial connector
and VirtualPC running on OSX (my iMac). A USB interface would be nice but it sounds
like much too much work for this package. I am looking for a nice (inexpensive) USB
connected EPROM programming solution since I've had much less success with a 
USB-Parallel connector and my current burner/software (a Needham EMP-10 and their
very old DOS software. Although I must add that the DOS software works fine in
VirtualPC but it just can't see the USB-Parallel port).
