first time I use a computer, I worked as a summer interin in a business, in the IT dept (they called IT but it was the Finance dept), with a punch card phillips computer
I hardly remember anything. I was young and fascinated by computers.
You had to carefully blind-type in a keyboard integrated in a table (no screen whatsoever), which was part of the system. Then, insert a virgin card that would get puncted, and ejected, and then I had to review the data entered.
I think I was typing accounting info.
And since then, all kind of computers and programmable calculators (I have a small old HP calculator collection, some with red led screen, which look really nice).
