GAL-programmer an breadboard

Because I want a PLCC-GAL as adress-decoder I need an GAL-programmer.
I searched the web - and found a simple programmer for 16v8, 20v8 and 22v8 GALs with DOS-software - Thanks to ChaN (1997/1999): Simple GAL-Programmer
I built it a little bit modified on the breadboard to burn a 16v8 - and it works.
With my 486'er-DOS-PC I compiled the source with the FGAL assembler and burned it with PGAL.

Why buy something? - when you can build it by yourself ;-)
