Dale, the best alternative for a Gal is just a Gal. It has free software
for a simple homebrew programmer and a free dos compiler (Palasm).
If you need the programmer schematic and software then mail me.

BTW I'm searching for a while for a homebrew programmer for MACH130.
I offer in exchange for this information free sample of MACH130 with
socket ! ( excluded postage payment )
