    IBM was a weird place in the 80s. Its depth and breadth had so many quirks in it. If you had the money - IBM would or could build you just about anthing.

    All kinds of internal tools and utilities that never shipped. Friends who were lucky enough to intern there in the summer came home with all kinds of goodies. They had a laplink-like utility that was lightning fast that could hook two machines together over RS232. easy and fast. beat copying files to floppies and doing sneakernet when upgrading.
