a brief but detailed exploration of the UF/uxn internals

Funktal is a functional programming language for the Uxn virtual machine, a tiny VM with 8-bit opcodes and 64 kB of memory. I have written about implementing functional constructs in Uxn’s native stack based assembly language Uxntal in a previous post.

Tny is a little console. You know, these things with a screen and a controller where you play games? Right, so it’s that, but very basic. In fact, it’s so basic that the size of its screen is only 16 by 16 pixels, its controller only has arrow keys and two buttons and its game cartridge memory is 256 bytes maximum. Oh and it doesn’t have any sound or color.

Psi-Forth is a reversible programming language taking its primitives from Henry G. Baker’s psi-lisp and Brent Kerby’s concatenative combinators. It’s not quite a htro-forth, but a stack machine made of cons cells or the reverse image of a linear lisp.
