Hi

... and once you find that old programmer, a copy of the OS that will run it's support software. Don't seem to have many Windows for Workgroups machines running around here any more ....

Then you hope that there's at least one floppy drive in the universe that will load what you *hope* is the right software for the programmer. 

I'm having a tough enough time finding a working example of a PIC programmer (with socket) running around the basement here. I have found two so far that I believe died a long time ago ....

Bob
