Why FRANK
01

One board, many machines

Switch between ZX Spectrum, NES, Atari 800 and the IBM PC family. Program and game images live on your MicroSD card, not on a ROM module.

02

Multiple video outputs

HDMI for modern TVs, VGA for older monitors, composite for the original CRT — pick the output that matches the era you are running.

03

FRANK OS

A desktop operating system for the RP2350 microcontroller. Windowed GUI with a mouse, terminal, file manager and apps — all running in 520 KB of SRAM. Window management, menus, dialogs, and preemptive multitasking, Windows 95-style, on a chip the size of a coin.
