This rare first version was modified in Poland and sold at Centralna Składnica Harcerska, the state-owned central scouting warehouse.
ROM version 1 is identical to the Timex 2068, except for the copyright message. ROM version 1.2 fixed the NMI bug. There is no software in the ROM to control the hardware on the daughterboard that was added.
The machine came bundled with a ZX Spectrum emulator cartridge for improved compatibility.
