Ugh ... that edge card connector and the RAM's vertical orientation was horrible. I tore mine out of the original case, found a real (mechanical) keyboard, built a better power supply and added a weed-eater style battery. I could move it around (unpowered) for quite a while before it lost it's memory and there were several times I took it to the local TSUG without having to reload the program I wanted to show off.
A local jeweler designed what he called a "winky board" and sold it to thousands of TS owners. It provided an AGC for both the audio input and audio output as well as shaping circuits to eliminate noise from the signal. This little board actually made storing programs on cassettes reliable.
Ah ... memories!
EDIT: It was a Winky Board - There are references here:
I have a ZX-81 (that I built from the kit version) and two TS-2000's in my basement, perhaps if you clustered them, the page could survive the HN effect.
EDIT: Two of them have the 16KB RAM expansion modules if the system is memory limited.
16KB! How luxurious, I had the standard 1KB. I saved my pocket money but by the time I could afford the expansion pack the industry (and I) had moved on.
You can do similar things on the Arduino with an Ethernet shield. There a single IC which contains a hardware implementation of the TCP/IP stack which takes the load of the AVR itself.

Gotta love this message. It conveys the feeling that this thing is for real.

Also, does anyone have a cache? Looks like it couldn't cope with the traffic.
