There are no drivers for this programmer. It uses old DOS software. I think they work under Windows 98. I was able to get it working under Windows XP using a program called allowio.exe. I run this from a batch file with the following commands:
allowio sp2.exe 0x260 0x268 0x270 0x278
You need the four port addresses shown since each one only covers 8 bits and the programmer uses 32 bits. If the base address you use is different than 260, change the code accordingly.
