So how did the engineers at commodore manage to fit a multitasking, graphic and sound supporting, realtime operating system that works in less than a megabyte of memory on an 880K diskette? With the release of WB1.3 they managed to do just that. If you ask anyone today if they can fit a multiastking graphical operating system in 880K and have it use less than a meg of memory they would say it is impossible. Now, granted Workbench doesn't have to have drivers for every device on the planet, but it still amazes me what they were able to do.
