Then how was Compaq able to get around it? The
original Compaq is
the only compatible I've ever used that -- BASIC programs aside --
ran everything a real 5150 would, without exception.
Classic clean-room reverse engineering. Compaq put the effort into it
that no one else did, meaning that Compaqs were the only clones that
exceeded the "95% compatibility" barrier until the Phoenix BIOS came
along.
