I love the super clunky retro esthetic!

Takes me back to a time when a laptop would encourage the cat to share a couch because of the amount of heat it emitted.

Amazingly quick as well. Pointless projects are so much better and more fun when they don't take forever!

Brilliant! I love it. Bonus points for using the eWoz monitor. It’s giving me the itch to build it.

Maybe this can achieve RYF certification.

What I really would love: modern (continously built) modern (less than 10 years old tech) devices ryf-cetified.

6502 based computers shouldn’t have a “dir” command. It’s “catalog” for detailed info or “cat” for the short one.

> 46K RAM

Not 64?

(Edit: I see part of the address space is reserved for ROM, but it still seems a bit wonky.)

The 6502 doesn't have separate io addresses so you need to fit all devices in a 64k space, not just ROM.

I love this! I’ve been working on a 6502 kernel. I have an arch trick to give the 6502 tons of memory so it can do a kind of Genera-like babashka lisp machine.

Good timing. My current weekend project is constructing something similar to the the first third of Ben Eater's 6502 design (last weekend was the clock module plus some eccentricities).

It occurred to me that given the 6502's predictable clock cycle timings it should be possible to create a realtime disassembler using e.g. an Arduino Mega 2560+character lcd display attached to the 6502's address/data/etc pins.

Of course, this would only be useful in single-stepping/very slow clock speeds. Still, I think it could be useful in learning how the 6502 works.

Is there relevant prior work? I'm struggling with my google fu.
