The TS2068 cpu was a Z80 just like the Spectrum. The Sinclair QL (for quantum leap) had a 68008 processor. It was available about a year (I think) before the 386. I have both, the TS2068 still works. I use it mostly for games. My QL doesn't have a power supply, Ive been meaning to build one but haven't had much time lately.
