Re the (ZX?) Spectrum, remember 'Ant Attack'? The world's first isometric game, I was gobsmacked!
My favourite computer games (late 80's) were Tanks and Adventure on PDP-11/RSX-11M (ASCII, of course 😁 )
My first computer was the Altair. Then Imsai and after that a Kim-1.
I still have the Kim-1.
Pdp-8e. I remember that one too. 12K of ram with decwriters II.
I went through cases of paper back then.
