Sintez and -Sintez- The Sintez and -Sintez- are Soviet clones of the ZX Spectrum developed in the "Signal" factory (НПО «Сигнал») within the Moldovan SSR in 1989. The original Sintez resembled the Spectrum+ model, while the -Sintez- was an improved version with a more common mechanical keyboard, an additional serial port, as well as the provision for an 8080 or related processor (e.g. 8255) to be added and used together with the UA 880. Whilst it is largely compatible with software for the ZX Spectrum 48K (and has two Interface 2 joystick ports) its hardware is configured differently from the machine it is based on – utilising a different memory chip set-up, and lacking slowdown when accessing certain areas of memory – with the result that certain applications and games may produce unexpected results, or crash altogether.
