The TS2068 has the same Yamaha AY-3-8912 programmable sound generator chip as the Spectrum 128k.
This is the chip's manual (PDF)

A coworker was giving these away, so I had to grab ‘em. I’ve always wanted to play with this computer - even knowing about its keyboard :D

Have a power supply and coax adapter on the way. Here’s hoping it boots!

Question: anyone know what the difference between the two RAM modules is (if any)? The one with the blue connector says Made in UK and the one with the black connector says Made in Portugal.

A *much* better version of the Timex/Sinclair 1000 manual, thanks to the epic scanning skills of @c64whiz

Update: got one, thanks to @c64whiz !

Is there a better scan available of the Timex Sinclair 1000 User Manual than this one on the Internet Archive?

It's a little bit cruddy, and every internet link seems to lead to it

I found the materials referenced earlier, a 1988 NASA paper explaining the theory and Sinclair BASIC code implementation to perform certain satellite orbit calculations.

Here's the paper as PDF

NASA Technical Paper 2811
An Economical Semi Analytical Orbit Theory for Micro-Computer Applications

The header of the code reads:

See a scan with some of the intricate Sinclair BASIC code in the images below.

UPDATE: PDF at the NASA documentation site found here:

Folks at the Timex Sinclair Online Group are doing some restoration work trying to help re-create 1980s NASA satellite orbit calculation code written for Timex Sinclair computers, up until now only existing in vanishing printed form.

Here's some more detail about the recently revived Timex Computer 3256 (a third-generation ZX Spectrum successor derived from the Timex Sinclair 2068 and the Timex Computer 2048)
