Hi, folks. I'll just explain a daydream I was having yesterday:
I was shopping around for a new/used watch and still love the retro aesthetic of old Casio databank watches. I'd love a programmable one, like the old Seiko/Epson UC ones ( link ) but those are getting really rare and expensive.
Smartwatches are cool, but bulky as hell and have a horrible battery life.
DIY watches are even larger & usually LED & push-button to view.
I know that there are embedded 6502 cores in tiny devices like Tamagotchis & photo keychains, so wouldn't it be cool to have such a core + RTC chip + dot-matrix LCD interface to an existing watch (like a Casio databank ) + UART interface for ASM program uploading?
Coincidentally, I just discovered 2 such ideas, but using watches & chips that I find less interesting due to limited display and more HLL programming:
https://goodwatch.org/posts/introducing-the-goodwatch/ Very cool...
https://github.com/carrotIndustries/pluto Neat, but more limited.

Anyway, is the embedded 6502 watch idea silly, feasible, etc.?
