Hey!! The title of the video is kind of misleading (I thought we could bake some new microchips in the oven... hahaha!) But, really, really, PLD and GAL are "obsolete" technologies which all of us, nerds, tinkerers and makers want to know. Thanks for sharing this info. I think I'll buy some ATF chips to experiment with. Currently, I'n working with FPGA and CPLD from Xilinx (XC9536XL) which are very nice for some microcomputers (address decoders and implementing some basic peripherals like IO ports and simple SPI port). The programmer I use is a Xilinx Parallel Cable III with official schematic freely available on the Web (1 parallel port plug, one 74HC125 chip and cables), but it needs some big propietary software like Xilinx ISE Webpack (from version 4, that I can run in and old laptop with Windows XP and a parallel port). Really nice all of these world about programmable logic. We love your videos!!! Keep up the good work!!! Cheers!!
I worked with GALs in the university - 30 years ago, we had a Xeltek Superpro parallel port universal programmer. Recently I found some GAL chips and think that could be cool to use them again. But universal programmers are expensive to program a half dozen chips. Excellent project, congratilations from Colombia.
You can get an XGecu Pro T48 to program GALs with. Most of these type of programmers are under $100 (usually between $50-$75) and use USB. I use mine to program GAL16v8's, GAL22v10's, EEPROMS, and EPROMS with.
