I built the Elektor GAL rpogrammer. Worked first time on my IBM XT,
absolutely no problems. OK, so I used the ready-etched PCB, and bought the
software, but there _could_ have been a design error.
 I bought the software becase I was building it exactly as described, and
therefore the software was 100% useful to me. There are 3 disks. the first
one contains the MSDOS executable to program a JEDEC file into the GAL,
and the other 2 contain a demo version of OPAL - a equation-JEDEC file
translator, PAL-GAL convertor etc.
Only one minor problem. It's almost impossible to box up the PCB, and as
it has mains on it, you need to. The transformer occupies the rear 1/3 of
the PCB, and there is a centronics socket on the front left edge. then
there are 2 LED's next to the transformer, and a ZIF socket fron centre. I
ended up bolting the PCB to a plastic plate, and fitting an ABS box with a
slot cu out of one side ofver the rear of the PCB, leaving the cenronics
socket and the ZIF socket exposed. I put the LED's on flying leads and
mounted them on the ABS box. Doesn't look too bad
