This is a Timex Computer 2068, produced in Poland by a joint venture between Timex and Unimor. The machine is somewhat
compatible with the Spectrum, and basically a modified Timex/Sinclair 2068.
The right joystick port was swapped for a parallel port in order to provide printer support. The internal speaker
was left out, and AV monitor output added using a standard Eastern European DIN plug for monitors.
Sound was upgraded to an AY sound chip, which was played through the monitor's internal speaker.
The machine came with an "Emulator ZX Spectrum" cartridge, which made the computer run ZX Spectrum software
