Timex Sinclair 1000. It was a modified version of the British ZX-81, that would work with US televisions. It came out in 1982, and the price quickly dropped from the introductory price of $99.95 because of competition from Commodore and others. When I bought might, I got the computer plus 16K memory pack for less than $90. I switched to the Radio Shack Color Computer the following year.
