It has been a few years since I have worked with the 6502 and 65816 processors. Most recently, my focus has been learning about FPGAs and developing my own FPGA PCB . Along the way, I designed some retro 286 and 386 systems, dabbled with a variety of microcontrollers, and learned more about PCB design. I thought it might be fun to build a single-board computer (SBC) based on the W65C265S microcontroller from The Western Design Center (WDC). This post will be updated as I wo

Recently, I received a request to walk through the creation of a two-layer, through-hole PCB in EasyEDA Pro. As I considered what kind of...

I am starting to experiment with different microcontrollers (MCUs). I am hoping to learn about 8-bit, 16-bit, and 32-bit MCUs -- from a...
