Taracta[/url]":1qvpezyl]You guys have forgotten that most of the early computer platforms were closed systems as in not readily expandable if at all. About the only early computers that were expandable were Apple's and later on PCs and as you can see Apple and PCs still exists the others are gone!
Let me introduce you to the
S-100 bus from 1974, which formed the backbone of the earliest personal computers.
Everything was modular - you started off with nothing but a chassis and backplane and then chose which boards to slot into it.
The Apple Mac's closed, integrated system was a novelty when it arrived ten years later (and an essential part of the design, since the modular approach imposed a definite support burden on the purchaser).
