Lotharek KRAKEN

Combines DivMMC microSD storage, USB HID input, four ROM slots, snapshot storage, dual-AY audio, and DAC modes in one ZX expansion interface.

For this compatible system (exact system): The seller lists KRAKEN among the tested systems. Confirm current KRAKEN and DivMMC-USB firmware before using accelerated machine modes.

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.

A current ZX Spectrum-compatible motherboard for an original 48K or Spectrum+ case, with real and FPGA Z80 modes, 512 KB of RAM, enhanced video, and extensive audio.

For this compatible system (exact system): This record is the current KRAKEN motherboard itself. It is designed to fit an original ZX Spectrum 48K or Spectrum+ case without drilling or cutting, but the case and other external parts are not included.

The assembled and tested Revision 1.5C motherboard exposed an order path on 2026-07-27. It requires a separate original 48K or Spectrum+ case, keyboard membrane, video cable, display, and 9 V AC or DC supply rated for at least 400 mA with the documented 2.5/5.1 mm plug. Power polarity does not matter. Lotharek separately sells its 9 V, 1.5 A PWR4 for KRAKEN, without a country-specific mains lead. The page's layout drawing shows Revision 1.5B, which differs slightly. External DivMMC or DivIDE hardware may not work in turbo modes.
