I actualy had that book at one time lol if you think about it computers still work almost exactly the same as they did back then they are just more complex and faster now

a Comadore 64 has all the same abilities as a 3Ghz P4... it has RAM and can do all the same math (just ALOT slower) and could write to disks and one thing it had over the current crop of computers is that its OS was embeded and boot time was like 0 LOL I sometimes wish they could do something to embed the OS in ROM now but that would make updates a nightmare.... I can just imagine people frying computers every time MS has an update and they toast the EPROM... LOL
