What is the NeXT workstation?

It is instructive to take a detailed look at the history of specific technologies which once differentiated workstations from personal computers. The modern reader might be amused at what was considered the target for a high-end workstation in the early 1980s, the so-called "3M computer": a megabyte of memory, a megapixel display (roughly 1000x1000), and a "megaFLOPS" compute performance (at least one million floating point instructions per second). However, this was an order of magnitude beyond the capacity of the personal computer of the time; the original 1981 IBM PC had 16 KB memory, a text-only display, and floating-point performance around 1 kiloFLOPS (30 kiloFLOPS with the optional 8087 math coprocessor). Other desirable features not found in desktop computers at that time included networking, graphics acceleration, and high-speed internal and peripheral data buses.
