The question asked exactly is the sort of thing that "the most trivial of web searches" wouldn't have answered as well as either of the replies already up.
One reply puts it into historical context, and educates the reader about the memory/persistence model of the ZX81.
The other reply points out that the lack of virtual memory and whatnot means that, in previous times, you needed to have the entire thing loaded into memory to execute something.
Without some digging and a knowledge of what to look for, those are non-obvious but useful points.
- TheOtherHobbes 12y agoWell - you could just search for "ZX81". First thing that appears is a Wikipedia article which explains how the memory and off-line storage worked. So I don't think finding this out would have been rocket science. Having said that, and having written my first code on a ZX81 (if you don't count an even older TI programmable calculator with even less RAM) I'm old enough to be amused by the question. :) However you slice it, chess in 1K was awesome coding.
