Ken:

   I've tried to make the David Tait programmer and was not able to
program my device. I admit that my breadboarded circuit was hastily
put together late one night but I would appreciate a copy of your
programmer's schematic/software if you didn't mind! I'm quite anxious
to get my PIC development on the road.

   Thanks,
