I thought the timex Sinclair 1000 win 2 Kbytes of ram was bad.

The membrane keyboard wasn’t great (the lack of a space bar was a wierd choice) but it did work. We had programs on casette and did get the 16Kbyte memory expansion.

I didn’t realize the Atari 2600 had basic, always thought of it as a game console.

You can buy this bad boy [attiny11] with no ram, only registers.
