Zillions of humans do drive automobiles and don't really understand what's under the hood. Never mind the zillions of users, tens of thousands of "computer professionals" / computer specialists write programs for computers and do not -- and need not -- understad how a computer really works. And like you, they could't care less! Anton, below that surface on which you live and work, there is an absolutely fascinating world. In some ways like honing and tuning an engine and then taking the car out onto the race track. A select group derives great satisfaction from exercising ultimate control over a computer. Some do this for a living after many years of learning, supplemented by years of hands-on work. Others do it for pleasure, writing kernels, interrupt handlers, debating weather it should be an XR, an SR or an SLR that clears a register. Just as a by the way: To write programs, the 1401 was an amazingly simple computer. It wasn't as intimidating as a 360 or an Intel 8080. It is a great machine for teaching "Assembly Language Programming" basics (except for the 3 index registers there are no user addressable registers or adders, and no IOS). Andreas F.
