Scott,
In MegaTraveller the old-time flavor of computers is completely changed.
I've only ever designed one MegaTraveller ship (this being an unplatable
experience) but what I remember (or mis-remember) is this:
Ship designs are created with parts of the ship that require CONTROL
POINTS. Then, control panels and holodisplays and whatnot provide
CONTROL POINTS. For example, an automobile design has a motor and
wheels that require X control points, provided by a mechanical panel
that provides X control points.
A computer is a device which multiplies the effectiveness of the panels
and displays (effectively multiplying the productivity of the sophonts
running the panels and displays).
For example, a small cruiser may require 1000 control points. You can
accomplish this by having a crew of 1000 sitting at mechanical panels,
or with a crew of 20 sitting in front of high-tech displays, or a crew
of 5 with the same displays and a computer.
There are no longer memory/cpu size or specific computer programs. The
effectiveness of a computer is handled abstractly as a die modifier in
combat and sensor operations.
I miss the old-time Traveller computers. They were quaint and
cantakerous, and added flavor to the game.
