@haitchfiveTimex Sinclair 2068-accurate attributes.
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:

2 REM An Economical Semi-Analytical Orbit Theory
for Micro-Computer Applications 1986-TimeX/Sinclair 2068

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

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.

Home ComputerMódem wifi para TS 2068 - versión 3 😎
Creado por Jorge Castillo, el módem se conecta a cualquiera de los puertos de joystick y requiere 4 transistores y un módulo ESP8266 con firmware zimodem.

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)

If you don't have the time to watch the full presentation and you only want to see TENET working between some networked Spectra, you may head straight to the practical demo here:

Inércia 2024 | Seminar "TENET: A deep dive into the lost ZX Spectrum Network" by LOAD ZX Museum
Few of us, even the most studious ones, probably ever heard of the Timex Computer 3256, a ZX Spectrum-inspired successor to the Timex Sinclair 2068, or believed it was forever lost to time.
Some incredible engineers unearthed the Timex Computer 3256 AND its peripherals, and revived it in 2024. The Sinclair-inspired computer, its networking interface called TENET (short for: Timex Educational Network), floppy drive controller, networking software for the classroom, and all. Restored, revived, and re-created in new hardware. It's nothing short of a Jurassic Park achievement, infusing life and embodiment to something that only remained in some faint ROM memories.

(it's a long one, but I promise every minute is worth it for the dedicated ZX Spectrum engineer)
