Writing a VM on top of gForth.

From SpainHackForth@21:1/5 to All on Thu Dec 15 11:22:28 2022

Hi all, just a little fun with Gforth, while it’s not working code, I wrote it : https://gist.githubusercontent.com/jemo07/ef81c852b08d8d4bb31b225300f2da78/raw/6650b9af51dfee69703b3199b9a118f1a884537c/uxn_jm.fs

looking at the uxn code… https://git.sr.ht/~rabbits/uxn/tree/main/item/src/uxn.c

I’m missing a couple of things, like reading the rom…. the case switch for the opcodes in hex, which should be part of the rom pase, sort of like:

: parse-rom ( add u - - )
begin
token dup
dup while
case
‘0x00 of uxn_brk endof
…
endcase
repeat
;

etc, Would be great if some of the Forth Experts would chine in and give some ideas… make it work?
