Here is a story in a similar vein. http://www.edn.com/article/509249-An_old_PAL_saves_the_day.php I have cross posted back to here

Accessing the "before" was difficult in a basement full of furniture from migrating children. Max has the photos now. I am sure the photos will raise a smile.

Thnaks Aubrey for that insight. I still have a handful of these devices (PALCE22V10 and the like) recovered from old boards and have wondered what I can use them for (maybe hexadecimal 7-seg or 5x7 dipsplay decoders or something, but I am glad there is PALASM and PCs around to do it instead of working it all out manually like you did... PS. No before and after pics??

The thanks should go to Aubrey for taking the time to write all of this down... ...maybe you have some tales to tell of your own?

Max, thanks for the memory refresh, PAL and GALS were my intro to replacing LSI in NASA JSC costumized hardware.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
