This is how my testing setup looks like to run #AdventOfCode programs on the #MSX. So far I did a couple of them in Turbo Modula-2, and it has been an interesting experience. It feels modern and high level enough to almost be unbelievable that this runs on a Z80 a little under 4 MHz, on any CP/M 2.1 compatible system (I think, not completely sure about the minor version).

The last picture shows how the language runtime can even produce stack traces for uncaught exceptions. I find both these features (exceptions, and meaningful stack traces) amazing for something that was done back in the 80s!
