My first computer was something that a couple of schoolfriends and me put together for the maths depatment at school in the sixties (1960's NOT 1860's as my nieces tell everyone). It used valves, wires and a series of on/of switches. Today I have a scientific pocket calculator that can do more a lot quicker.
First "PC" was an Amstrad with one 128kb 3" (not 3,5") floppy disk and no hard drive. You loaded the programme with one disk, took it out and then used another for the data you were working on. It had a green screen and a dot matrix printer as part of standard kit. I also bought a mouse for it. The wordprocessor was Locoscript and it had a cad programme called Dr something or other. Total cost was about 400 pounds.
Gave it to my nieces when I bought a new machine. They used to use it to write up homework, etc. It finally died when their house was flooded in the early nineties.
