Timex Sinclair TS1500 section[edit]

This section is wildly inaccurate. TMX Portugal had nothing to do with the TS1500. It was designed in the US as a 16K replacement for the then ageing TS1000 at the same time as what would become the TS2068 was being designed. Far from being a slight upgrade it was a completely re-engineered machine. It did not use a ULA, using a conventional custom chip instead. The ROM information is correct however. My source is a transcript of a conversation with the former head of engineering at the computer division of Timex. —Preceding unsigned comment added by 93.96.235.195 (talk) 00:40, 29 July 2010 (UTC)[reply]

Clock rates slightly different[edit]

The Timex-Sinclair 1000 CPU was also clocked slightly faster (3.5 MHz vs 3.25 MHz) than the ZX-81 to make up for the differences in the TV Standards used in North America vs. the UK. Where timing can be important, programs written on one and ran on the other seemed to "never sync up". Also, later T/S-1000's in the United States market also sported a heat sink on the ULA chip- a known source of thermal issues.

Perhaps instead of just merging the ZX-81 / Timex-Sinclair-1000 pages, one could possibly do a "Family Page", like the Apple 2 line. In reality, the ZX-81, T/S-1000 and T/S-1500 are really the same family of systems ? Any thoughts on this idea.

This way, we can go into detail on the ZX-81, and explain the differences in smaller sections. Pardon any mistakes- I'm VERY new here :) — Preceding unsigned comment added by Atrentphillips (talkcontribs) 23:44, 11 April 2012 (UTC)[reply]

Timex Sinclair 1000 Date of Manufacture is wrong.[edit]

I owned one prior to 1980.


Plastic one piece keyboard similar to keypads used on microwave ovens.

8k of memory
expanded to 32k of memory at a cost of $99

No Storage. Power off meant all work lost.


After hours of typing in basic program for the flight simulator that was in the book that came with it I ran program for 2 minutes before hearing:

Mom's favorite order: "Turn that thing off and come to dinner!"

Oh, the pain of it...
