From the project
Modern platform to run retro CPUs
Run real vintage CPUs on a modern Cortex-M7 — with a debugger, assembler and disassembler built in.
- CPUs — every target supported and planned, with the variants each detects - Hardware — the board stack, signal naming and the awkward chips - 3.3 V base — planned second base board, its keying and what it unlocks - Debugger — full command reference - Build & run — toolchain, flashing, serial ports - Samples — the programs and how to run them - Demos — recorded terminal sessions for 20 CPUs
