1990, meet 2018: How far does 20MHz of Macintosh IIsi power go today?
It turns out you can use a nearly 30-year-old bit of hardware for today's demands.
@uranther @ajroach42 "barely enough power to run more than one application"
**COUGH**Amiga**COUGH**
20MHz 68030 would have given mainframe-class performance with a proper operating system for it. Hell, I still remember how pleasant a 20MHz VAX was with over a hundred attached terminals.
AmigaOS wasn't perfect either, but its use of preemptive multitasking made all the difference. MacOS System 7 was pretty, but it was a very sub-optimal design due to its System 1 compatibility requirements.
@uranther @ajroach42 (For starters, it used cooperative multitasking. But even then, a task switch was *very* expensive because it had to swap out a chunk of globally shared address space. It was like trying to get MS-DOS "taskers" to multitask by faking a task-switch as quickly as possible.)
@vertigo @uranther @ajroach42 MacOS's cooperative multitasking from that day - when a user held down the mouse button for too long, the network stack wouldn't get a chance to run! http://www.catb.org/jargon/html/D/Don-t-do-that-then-.html
@niconiconi @vertigo @uranther @ajroach42 little known fact that #Apple decided to replicate this user experience on iPhone 4: https://www.wired.com/2010/06/iphone-4-holding-it-wrong/
History repeats itself: the article even starts with te same joke!
