retro/816

Port of RETRO Forth created by Charles Childers to C256 Foenix, a retro-computer based on 65c816 CPU.

This port is in infancy and there are dark and spooky things inside, but at this moment is able to run simple code in 1:1 pair to one of original interpreters (vm/nga-c/barebones).

It runs in Foenix IDE, it is also possible to run current, unmodified version of this port on go65c816 emulator (use retro.ini parameters file here).

obligatory screenshot

building

You will need a 64tass assembler.

rough edges

inst_di is somewhat borken - it is very crude and doesn't works with signed values
currently there are only two devices available: keyboard and standard output

latest changes

2021-02-28

rename nga.asm to barebones.asm to better reflect which part of RETRO it corresponds to
