After I fried my mail ordered ZX-81 because the memory pack shifted I presume. I bought one of these from a local store. I also got the 16k memory pack by Timex Sinclair too. This time I used velcro to make the connection more stable and this worked pretty well.
The computer came bundled with software (whereas the ZX 81 did not) on cassette for Personal Finance, 2k games, 16k games, and Flight Simulator. I played flight simulator for hours on end. I also wrote some programs for it including a cassette file based inventory program in which you read the whole file in from cassette into arrays. Then you could manipulate the files as needed and when you were all done, you could write the file back to cassette. I also wrote an invoicing program but could never really test it because I never got a printer for this computer.

I remember this being given away in boxes of Cheerios, like a "prize"

I had a Timex Sinclair 1000 with the 16K mem expansion and thermal printer. This thing was a throwback to the dark ages of time sharing when you used a teletype for input and then waited around for something to happen. In black and white. It was a computer however, and the esoteric methods of key entry were the initiation into a special cadre.
