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.
