I’m jealous that older generations get to say they wrote their first program on iconic hardware. Computers of my time were much faster, but they were very generic.
My first PC came with instructions on how to connect the keyboard, mouse and monitor. I recall thinking it was really strange that something could be sold without instructions on all its functions. Until then every electronic device I'd bought came with instructions that were 'complete' in the sense that everything you could do in normal use was documented.
