The 256-Series is a series of computers of various sizes and architectures that I constructed. Currently most of them are still a work in progress.
The Femto-5 (WIP):
A Von Neumann 20-bit computer, designed and optimised for CircuitVerse, with a planned microcode writer, assembler, and compiler.
The Femto-4 (v2.6):
A Von Neumann 16-bit computer, capable of running simple games, driving a 16x16 screen or a 32x32 screen, with an assembler, and a compiler for the Femto-4's high level language, Phemton Lite (a1.0).
The Atto-2 (WIP):
A Harvard 8-bit computer, capable of running simple graphics.
The Zepto-1½ (WIP):
An 8-bit register machine
The Zepto-1 (WIP):
A 4-bit register machine.
The Yocto-½ (v0.1):
A Turing Machine.
The Yocto-¼ (WIP):
A true 2-bit computer. It's basically useless.
The Ronto-¼ (WIP):
A true 1-bit computer. It's entirely useless.
The name of all of the computers and the series as a whole is reference to the Pico-8.
