* The TC2068 is the Portuguese made European version operating at 50Hz on a 230–240v power supply and generates a PAL television signal (used throughout Europe, except in France where SECAM is used instead) with a normal expansion bus. Both machines feature an [[AY-3-8912]] sound chip (not 128 compatible), an extended version of BASIC in 24K of ROM (semi-compatible), two non-standard joystick ports, a cartridge dock (not IF2 compatible), and a new ULA with extra video modes, but some incompatiblities. There is also a Polish clone of the TC2068, called the UK2086, which substitutes an RS232 port for one of the joystick ports. | * The TC2068 is the Portuguese made European version operating at 50Hz on a 230–240v power supply and generates a PAL television signal (used throughout Europe, except in France where SECAM is used instead) with a normal expansion bus.

* The TS2068 is an American machine operating at 60Hz on a 110v power supply and generates an NTSC television picture (just like the Spectrums sold by mail order in the US by Sinclair) but with a [[Timex TS1000|TS1000]] (ZX81) compatible expansion bus. | * The TS2068 is an American machine operating at 60Hz on a 110v power supply and generates an NTSC television picture (just like the Spectrums sold by mail order in the US by Sinclair) but with a [[Timex TS1000|TS1000]] (ZX81) compatible expansion bus. | ||
