A very belated... Thanks!

Hi all, Started working on a Q*bert clone for my HBC-56 homebrew 65C02 /TMS9918 / AY-38910 build (just for fun). Very early days, but here's a couple of videos showing the progress so far: Emulator: Real hardware: 65C02 CPU is running at 3.6864MHz.It's using Graphics II mode of the TMS9918A.My first attempt at PCM audio on my hardware (a pair of AY-3-8910's) driven by 65C22 VIA timer interrupts at a lowly 4096Hz. Can definitely go a fair bit higher, but will eat through my 32KB ROM pretty quick. All code, schematics, emulator, etc. on GitHub: https://github.com/visrealm/hbc-56

Thanks. The two main sources of information would be GitHub https://github.com/visrealm/hbc-56 and Hackaday https://hackaday.io/project/180904-hbc-56-6502-tms9918-on-a-backplane There are schematics on github and all of the 6502 software is there. Also the emulator (with source code) which can be run on a desktop or browser.

Previously, my web-based emulator ran BASIC by default and you could drag ROM images into it. I've just added support from loading server-side ROMS, so now you can try it yourself: https://visrealm.github.io/hbc-56/emulator/wasm/?rom=breakout A couple of limitations: Audio doesn't work in the web-based emulator. You will need a keyboard. It's all very BETA. #worksforme Have at it. Oh, I've also cleaned up the code: https://github.com/visrealm/hbc-56/tree/master/code/6502/breakout

Just started working on a breakout clone for my homebrew 65C02 build. Mainly to have a go at working in Graphics II mode beyond simple demos: All source code (65C02 assembly) is available: https://github.com/visrealm/hbc-56/tree/master/code/6502/breakout . Edit: The video is a little washed-out. It does look better in the flesh. Here's a screengrab from by emulator:
