I don’t know whether it is ‘the best’ but one that I find springs to mind quite often is a moment with a new Christmas present once. It was one of those walk-along-then-spin-and-shoot robots - a very simple thing, since this was in the early '70s. However, my memory is of utter joy and entrancement as I set it going then leapt out of the way, on to the furniture, before it opened its chest and fired.

It must have been a present from my parents, so they were probably happy that I liked it. Whether they were quite so happy after the first hour or two of the same thing, I don’t know.

No - you could get the 81 both prebuilt or as a kit. The kit was cheaper, clearly, and was the only one we could afford.

ZX-81 which my brother and I built from a kit. I was astonished when it actually worked.

Right handed. My wallet is in my left pocket, since anything that I need to do with it will involve holding it with my left and doing the thing with my right.

Both my phones (home and work) are in my right, since I can carry out basic functions on them one handed.
