Of course that pages about Sinclair
computers must exist in a Website about Timex computers since Timex computers were
developed from Sinclair computers. TS1000 is a ZX81 clone, but TS1500 is an evolution of
ZX81. Even TS2068 is an evolution of ZX Spectrum, not a direct clone. Sinclair computers
where made and sold by Sinclair Researsh Ldt owned by Sir Clive Sinclair until the launch
of ZX Spectrum 128K+ and Sinclair QL. Later models were released by Amstrad, which buyed
the Sinclair computer copyrights from Sinclair Research Ldt.
MK14 - the first computer sold as a kit;
ZX 80 - the first of the ZX line, 4K ROM, 1K RAM;
ZX81 - a better ZX80, 8K ROM, 1K RAM;
ZX Spectrum - the star of the ZX line, 16K ROM, 48K RAM and colors!

The following ones are made by Amstrad, witch buyed the rights of Sinclair computers.

ZX Spectrum 128K Plus 3 - like Plus 2 but the tape recorder was replaced by a 3" disk drive, new ROMs (64K) to work with the disk drive and with the new centronics printer port. Less compatible with original 128K because of the new ROMs.

Amstrad sold the same computer under the name Amstrad, but it a white case, the Amstrad PC20.
