Didn't see anything in the manual about upgrading the components of your deck. In the cyberdeck interface you cannot access the inventory or character screens (right click just exits the interface). Is it non upgradable? I am on the very first screen of the game, and already have a 4TB memory chip. I figured I would replace the 1TB chip in the deck with that, but perhaps you can only build a whole new deck with parts you collect?

You need to click once on the upgrade item so that it becomes your cursor, then go to the top of the screen, click on "cyberdeck" and then click on the part you want to upgrade.

Yes, clunky...
