I type "LOL" occasionally, but this time I ACTUALLY DID.
Of course, even before that processor was outdated I was filling up 4K regularly. - SO I made extensive use of the cassette-tape backup.
Imagine if memory was still 2.5 cents per byte.
oddly enough, I have more of a need for RAM in my phone than my desktop.
But if you want a good laugh, flex your google-fu and compare your phone's memory and processing capacity to that of NASA's Mission Control center when we launched Apollo 11. -- Not the lunar lander (that is outclassed by modern parking meters), I mean the Mission Control mainframe back on earth.
That really drives home how crazy the whole "moon by the end of the 60's" thing was; and how amazing the success truly was.
Long computations which yield zero are probably all for naught.
