# US ZX81 and T/S 1000 Hardware

I’m not much into hardware, but I believe that things should be documented. After some discussions during the T/S group Zoom meetings, I thought I would see about documenting some ZX81 and T/S 1000 hardware aspects.

On the Sinclair ZX World forums there is a fair bit of information about ZX81’s. Those folks are much more of an expert than I am, but I realized that mostly they were talking about the European ZX81’s and had very little information on the US ZX81 and T/S 1000. I figured that I could document that.
