I’ve recently been working on an ESP32 variant of something similar [0]. ZMOB-like designs are so much fun to think about.

I got as far as getting BASIC to run, but struggled porting FORTH to z80. Existing Z80 forth interpreters I found need almost 64k but wiring up some static-RAM hasn't yet given me a functional system so I'm hazy on what is wrong; either my real-RAM or the interpreter itself.
You probably didn’t do something that silly though.
