AvailableChecked Jul 27, 2026	BISON FPGA DivMMC TurboSound 2xAYby Lotharek divmmc microsd esxdos 512kb turbosound dual ay covox soundrive joystick mouse fpga edge connector	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. 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.

The seller exposed a login-or-register-to-buy path on 2026-07-27. Its published testing covers the original 48K, original 128K, Pentagon, and KRAKEN. The page says +2A and +2B compatibility still has known issues and that keyboard-mapped USB input will not work on +2A or +3 because of data-bus coupling; those models are not attached. Treat the described resistor workaround as experimental, not an installation recommendation. Follow the separate FPGA and USB-controller update procedures exactly.
