No wonder it won't work with a USB converter!  I think you'll be very lucky to get it to work even if you do supply the programming voltage, unless anyone knows different?

I've since started playing with it, trying to make it behave.  It's
not happy at all.  It does seem to erase the chip, when it attempts to
program the process is very hit and miss.  It seems to manage to
program some addresses, but not others.  I'm going to have to do more
reading and see how I can rig this up.

Thanks for the help.
