Part of the fun of retro computing is looking at and figuring out the schematic diagrams. I found that once I learned a few basic patterns in circuits I could much more easily understand what the overall circuit was doing.
In this video I share my personal top 10 patterns I’ve learned to recognize in the retro computer schematics. I use examples from the Radio Shack Color Computer 1,2 and 3, the Commodore 64, and the Apple II.
If you are starting out in hardware hacking on your retro computer, this video may help you out!
