MOS 6502 Transistor Replica

The 6502 is the famous processor found at the core of such influential computer systems as the Apple ][, the Commodore PET, the Atari 400 and 800 home video game consoles, the BBC Micro, and the Tamagotchi digital pet and now it has been realized as a MOnSter PCB using transistors.

USBuddy

Do you sometimes develop with USB? I do. So I need to access data lines, bus voltage and I'd like to easily monitor the current too. I made myself a small companion (43.5 mm × 22.5 mm, 9.5 g) to do that. Just a simple breakout board with one connector in and one out. And a little extra to make things easier. I call it USBuddy.

The MOnSter 6502

So, I made a thing. A really big thing. Really big and really crazy.

You might have seen my discrete 555 and 741 IC electronics kits. Well, a while back I had this idea about creating a discrete version of a microprocessor, but it just sounded too difficult, time consuming, or impractical. And part of me didn’t want to do it, because it just sounds so tedious to design–at every stage, I was secretly hoping to find a show-stopping problem. But part of me was really interested to see if it could be done.
