Man I'm old. I remember 5 and 1/4 inch floppies and 286 CPUs that you could upgrade to be faster for certain operations by buying a math co-processor. It was literally a DIP style IC chip youd insert on your mother board.
I remember upgrading my computer back then with one. It was a store in the city that had this glass case with various IC chips in plastic cases, no box or pretty packaging but it had a sort of sterile beauty to it with a little holographic sticker on it I think.
Its weird I was pretty young at the time, barely into my double digits. Only went to that particular store once. But I can recall exactly what the inside of the store looked like and even the city block it was on.
It invokes strong feelings of nostalgia.
@Venkatmangudi My first computer was pre 286 too, the 286 was my second computer.
My first computer was from the Atari 8-bit family, then I learned on Commodore at school then apple ][e at my next school.
@freemo computers came to India only in 1987 or so. At least the PCs. The big ones were there, but not generally available for the masses. I'd have loved to have learned with the commodore or the Atari.
