I am getting back to my early computing roots and buying some TS1000 and ZX81s on Ebay. I starting doing a massive search this weekend·for ZX81 / TS1000 sites and information to see what is new in the last 10-20 years since I had been active. I have also been spending the last year focusing on BASIC Stamp II's and other microcontrollers such as the SX-28 and a little on the new Propeller chip.
I found a very neat TS1000 site from Ted Szczypiorski:

What you will first see is a TS1000 movie player showing an Apple IPOD shuffle commercial which is pretty impressive.
Then at the bottom he shows how he used a Basic Stamp II as an RS-232 to Timex Keyboard Interface (TKI). I sent him an email from his site requesting info on the schematics, code, etc. I would love to build this and possibly modify it with a cheaper SX-28 microcontroller.
Great job Ted!

I will probably port this over to an SX-28 at some point once I figure out how this works.
Thanks to Ted!

Maybe now I can stop using my ZX81 as a doorstop...
(Yeah, the keyboard is shot. )
