One of my first real projects for the GAL was to create such a chip. I have an old PAL databook that was published by National Semiconductor in 1982. I pulled … Read moreGeneric Array Logic Hexadecimal Display
I’m going to continue this series while it’s still fresh in my mind. In case you missed it, part 1 is here. I learned electronics when I was in High School. I had two years of electronics classes and I also built circuits out of digital logic gates as a hobby. This is in the … Read moreDigital Electronics for the Beginner (Part 2)
I’ve been blogging a bit about digital electronics lately. One of the devices that I have never had the opportunity to experiment with is the Programmable Array Logic or PAL. The last time I built a circuit was when I was in College in the early 90s. At that time I owned a Mac Plus … Read moreGeneric Array Logic Devices
