(Bunch of IBM PC - TI-99/4 - Timex/Sinclair - Apple - Commodore - RS stuff deleted for brevity). Replace "computer" with "desktop microcomputer with keyboard and video display" and I'll agree that your list makes sense. (Though the Alto doesn't quite fit that category.) Unfortunately your list completely neglects the non-desktop micros, especially those without integral video, minis, and mainframes... Tim.
