Building a Minimalistic Virtual Machine

the jvm already exists and you can run ancient compiled class files with it.

The level of cynicism on HN is sometimes really depressing.

FTFY.

I’ve been toying with the idea of taking an ancient bootstrapping JVM implementation, forget which now dead project it was written for, dusting it off and doing something similar to your project. None of these new millennium fancified features — compute like it’s 1996.

Though I’m mostly interested in compiler tech, as an amateur, and don’t really want to delve too deeply into VM theory.

Time is the main factor holding me back though…sigh.

If you want to compute like it's 1986, I think it would be fun to build a BASIC interpreter for UVM. Bonus points if you do your own text rendering on a blue background and you add simple primitives for 2D graphics.

ok, but not everything wants the baggage that comes with the JVM.
