Make W7 64 bit play nice with your Programmer
External EPROM burners are pretty handy gadgets to have around. They obviously can read and write EPROMS, but often times they will also handle a pile of PIC's, some AVR's, and other programmable logic like PAL/GAL and CLPD's. While you can often find old models floating around for cheap (or free in my case) there are a few issues to be hammered out.
Typically the models you're going to get for a song and a dance are old parallel port models that use software in MS-DOS or Windows and hasn't been updated since. The software typically bit bangs the port using it like a 1 byte wide GPIO line, and this was a common trick, that is long gone from current operating systems by default.
[Doug] sought to find a solution to using one of these gadgets on Windows 7 X64, and lots of Google-fu, poking at libraries, and a little code modification he does just that getting his Sivava Willem EPROM programmer working like a champ on a nice new i7 with a parallel port add in card.
