Hope these notes help you up to speed quicker than I. After that, the programmer and software worked easy-peasy. I spent too much time diddling with the parallel port card and software while I had J4 jumper in wrong position, but stumbled on the right configuration just as I was running out of steam and looking for an old PC to test with.
Yellow PROG LED lights during PC boot (I assume when the computer is testing the parallel port for attached hardware) and when there is chip programming activity. Green EPROM LED comes on with power supply.
I also installed/built the Linux geepro counterpart and got that working as well. Fiddling around with software, I ended up with the 64bit "workaround" provided on the CD that comes with the card, augmented by Downtown Doug Brown's notes. I used an external 12V supply from an discarded router. Printing in PLCC adapter in same orientation as printing on card, in the EPROM chip holder. Review jumper settings: J1 toward "bottom" position, J2 to "top" position, J3 to bottom of card, J4 to EPROM side, J5 closed, J6 toward "bottom" of card, J7 toward "top" of card, J9 closed. It took me awhile to get everything setup to work with Win7 64bit home-built computer, Rosewell PCIe add-in parallel port card. The Willem PCB6 programmer kit works very well for me, needing to "adjust" the 28F020 chip in an old HP8711C. With its complete new professional design, True USB PRO 40pin willem programmer GQ-4X is the first & exclusive Willem universal programmer in the market.
