Combines DivMMC-compatible microSD storage, 512 KB of expansion RAM, dual-AY audio, DAC modes, and configurable joystick or mouse input on the ZX expansion bus.

For this system (exact model): The upstream project reports testing on the +2A. BISON's automatic Amstrad selection depends on the expected 9 V edge-connector signal.

The seller exposed a login-or-register-to-buy path on 2026-07-27 and documented firmware 1.5. Power off before changing the edge connection or input mode. Automatic Sinclair-versus-Amstrad selection depends on 9 V at edge pin 3B; compatible clones without that signal need the documented modification. Firmware updates require a separate Gowin programmer and removal of the flash ROM. Prepare a separate FAT32 microSD card with the supported ESXDOS release.
