In this blog post I am going to dive a bit deeper into the ezPLA chip, investigate the reason why it does not work in all C64 machines and then try to fix it.
A while back I created a prototype board for the PLA replacement chip for C64. It was time to make a PCB out of it. In this blog post I will describe the steps that I did to design the PCB using KiCad and manufacture it using PCBWay prototype service.
Teensy 4.1 can be upgraded with up to 16 Megabytes of PSRAM. Here I describe the process.
After collecting all the components needed for the Atari board it was finally time to solder them. But what are the chances that the project would work on first attempt? In my case it didn't and I will describe here my process of troubleshooting.
This is the micro:bit. It is a pocket sized computer system with motion detection, a built-in compass and Bluetooth technology that can be used to learn programming and electronics.
A while back I also made a prototype for C64 PLA chip replacement, but I never did any further tests and completed the project. I thought that it was time to do some more tests on the chip. But will it pass the tests? Let's find out...
