The Macintosh turns 30 today. Oddly enough, it still has about the same market share as it did three decades ago.
A typical application on a 128K Mac had about 85K of memory available; the rest was used by the system, mostly for the bitmap display. A simple calculation shows that copying a 400K disk should involve about 5 or 6 swaps. Five disk swaps was barely tolerable, but, as early Finder users will remember, occasionally it would take well over 20 disk swaps.
