Current shortboard and longboard v4.0 files and an easier-to-assemble v4.0.1A variant were available on 2026-07-27. No assembled seller was verified. A complete build needs both PCBs, components, assembly, a Raspberry Pi 3B+, Waveshare RP2040-Zero, microSD card, original C64 or Mechboard64 keyboard, suitable case, and power. BMC64 itself is not compatible with Raspberry Pi 4B or 5. Sources BMC64 PCB repository BMC64 emulator repository	BMC64 PCB System Exact model	BMC64 PCB project and build files BMC64 emulator

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.
