100%.

3 years ago I modified his 6502 breadboard project and added a keyboard, display and then I modified MS Basic to get it to run. Also, I found a way to extend the RAM to 31kb. I called it eater-one.

All of his videos and kits are a must if you never understood how a cpu works. I highly recommend them.

Another suggestion is Anders Nielsen's channel - his video on a single breadboard 6502 computer (really a 6507) with a RIOT is really good: https://youtu.be/s3t2QMukBRs
