The Penton RAM and Core are shown to need 3 neonparts/gold parts, but in practice only need 1.

The Teleport Block recipe shown in the Tech Tree does not work. For debugging purposes I installed JEI, which showed a different recipe with a button in the top middle slot instead of Aluminum Plates, which does work.

Both should be fixed in: 26.3.127

Both do seem to be fixed.

I've progressed further in the mod since I made this issue and noticed a few more inconsistencies with the Assembly Table recipes:

TCT Core:
Tech Tree says: 4 goldparts
Actual recipe: 2 goldparts

Note that TCT Memory takes 4 neonparts vs the 2 goldparts of the TCT Core. I'm not sure whether they are intended to take the same number of parts.

Ultimate Chipset:
Tech Tree says: 2 silicon
Actual recipe: 2 quantanium

Thank you for report, fixed again: 26.3.218

This indeed fixes it. Thank you for your effort.

A question:
If I notice some typos or want to improve the wording of the English text a bit, I should make a pull request to this repository

right?

Yes :)
