THE ZX-81 is beginning to take off in the States. An agreement between Sinclair Research and the American Express credit card company has resulted in a flood of orders for the machine. The credit card company sent a direct mail offer to its two million card-holders in the U.S. at the end of May. In…

Another book which will be of interest to ZX-81 owners is The Ins and Outs of the Timex TS-1000 and ZX-81, by Don Thomasson. The book looks as if it were written for a readership in the States but it has some relevance in Britain. It explains the hardware of the ZX-81 and includes a…

The TIMEX 2040 thermal printer is the standard printer used with the American version of the ZX-81. The US version of the Spectrum had yet to appear at the time of writing. It works with a different paper, 4 1/2 in. wide plain white paper with a special coating sprayed on to the top of…

TIMEX is learning from its close association with Sinclair Research and introducing its own low-cost microcomputer in the States.

It is a widely-held belief that whatever happens in the United States will, sooner or later, happen on this side of the Atlantic If that is so, we must view with some anxiety the sudden withdrawal of Timex from the home computer market in the U.S, a withdrawal announced with a somewhat ominous prediction from…

One blot on the rosy scene of the Sinclair Research financial year was the disappointing performance of the Timex Sinclair 1000 in the U.S. Two factors seem to have affected sales badly, the raging personal computer price war which brought the selling price of the TS 1000 crashing to a derisory $39 and what some…
