If you ever had a ZX80, that thing got even hotter than a QL. It was
rumoured back then you could fry an egg on it, although I'm not sure anyone

2. Spectrum microdrives would not format cartridges on a QL, though you
could usually read and write OK. I think there was a bit of a speed
difference IIRC, that Sinclair made changes to make QL drives work at
higher capacity.

little reminiscence
last week while we had rather more seasonal temperatures (ie it was warm),
one of the most annoying aspects of computing in the 80s rapidly
