An ATmega1284-based computer with color video, sound, built-in mechanical keyboard, and Forth interpreter in ROM. This is the first in a series of videos I'll be uploading about this project. It gives a high-level overview of the project and demonstrates its capabilities.
Specs, code, schematics, etc here: https://github.com/74hc595/Amethyst

Forth interpreter in ROM.
Who could ask for more? Nothing else stacks up like a good Forth!
How does Forth even work in a machine that does not execute out of RAM?

I've recently converted the code from the chiptune player "Noiseplug" to work with Tiny84A and M328p
it was intended for the tiny9, tiny10.
Original work from Joachim Fenkes "dop3j0e"
https://github.com/dop3j0e/noise...
The remarkable thing about the code is that it uses ~32 bytes of sram and less than 1000 bytes (takes up 1300 bytes on bigger chips) of code in assembler
Here's a video : https://www.youtube.com/watch?v=ycfYZpyQRzw
Fogot to say: this might be a light weight solution to your sound system... Good Luck!
Nice job on the computer effort!
One uses a virtual machine.

OP has the forth interpreter and main words in ROM, and there are some ASM code.
New forth words will always (in normal forth) be put in RAM, and there is no ASM is involved. (unless you specifically write ASM code, like inline ASM in C ).
(in forth a word (like a C function) is just made from other words, numbers etc.)
