Though I really like the concept of building a new device which incorporates the inherent ease of programmability of the computers of yore, I think the 6502 is just too weird and limited for doing so. For example, in order to cram a halfway decent amount of memory into the thing they had to resort to bank switching. At the least they should’ve gone with a 65816 (apparently they tried but they initially had some problems with the '816 address bus multiplexing).
For example, due to parameter passing often being done via the zero page, recursion is unnecessarily hard on the 6502, whereas one could argue that recursion is one of the major skills to master for any programmer.
@irdc@feoh All programmers need to learn recursion and fully understand it so when they encounter it in the wild they can properly analyze what it is doing and replace it with non-recursive code.
One could, but I would argue that this idea pre-supposed a very ascetic class of programmer, and that depending on one’s goals in learning how to program, recursion can be a useful concept but saying it should be the one litmus test for any learning platforms seems highly questionable to me.
They learn how to program in a more efficient way that makes better use of limited memory and CPU cycles. Which frankly is something modern programmers and game designers could very much benefit from considering how bloated and unoptimized much of modern software is, probably because they didn’t need to think about whether computers can actually run it.
There’s plenty of choices. If you want that retro vibe go for a 68k, if you want something neat but obscure (and are willing to use an FPGA) choose the pdp-11, if you want to go with the flow then use risc-v.
But please pick something that’s not actively fighting modern (that is, not 1970’s) programming techniques.

Also, how would that ‘weirdness’ impact using the device in a teaching context?
People would learn bad habits.

A non-recursive recursive descent parser isn’t any easier to reason about.

What would you like to see instead? Z80? Something else?

Are there any off the shelf available 68K based computers these days? I wasn’t aware of one but that would be cool :)
