IBM's personal computer of 1981, whose open design became the standard for most PCs since.
When I first started, I was using this Texas Instrument TI-99/4A and it had a basic built-in language interpreter. I used it for about a year and then the IBM PC came out.

Prudential Insurance had a mainframe in the insurance company, looked after by IBM, but they didn't know anything about the IBM PC. So they had to hire a micro person, me, in other words, to go in and network the whole system for the dealers.
