A video I made some time ago so ends rather abruptly when I start doing the RAM upgrade.

I thought it would be, maybe, interesting showing how to convert the machine to composite video by gutting the UHF modulator can and using a transistor and some resistors.

The ZX81 and TS1000 are essentially the same, however the the RCA socket is in a different spot. Oh, and the TS1000 comes with 2KB of RAM instead of just 1KB.
