Hi all,
Has been a while since my
last project. I decided to tackle my first PCB-based project and have always wanted to do a backplane, so I did (both).
Designed and ordered a custom backplane and a bunch of custom proto-cards for it, then got to work building out the cards.


So far, I've built 6 cards:
- 6502 CPU
- Triple-mode clock
- RAM/ROM (32KB of each)
- LCD card (supports standard character LCDs and Graphics LCDs)
- TMS9918A based video card
- Dual AY-3-8910 sound card
I also have a NES controller board (currently on a breadboard). Enough hardware to start a simple game, so started work on an Invaders clone (6502 assembly).

I have all the code and most of the schematics on
github.
Created a project on
Hackaday.
I do plan on creating a few more YT videos on the project (going into more detail) over the coming months.
Cheers
Troy
