This is a Timex Sinclair 1000 with a vLA81 micro controller (ULA replacement), with 32k between 16385 to 49151, digital composite video output, and a new TS1000/ZX81 heavy duty replacement keyboard. It comes with a 9 volt 2 amp modern regulated power adapter, and has been fully functionally Tested to verify 32k operation, and played a TS 16k game, and the computer has a crystal clear high contrast picture.
Please bear in mind that the old connectors and jacks may need cleaning to ensure good stable operation. The coax Composite video cable should be less that 48" long to ensure good compatibility with the 75 OHM load. I recommend using a small amount of WD40 on all the cable jack ends.
NOTE: Only ships to continental United States
