Obviously many people won't be old enough for them....
Having started coding on ZX-80, I remember the 640Kb base-RAM limit once set by "guess who" on the 90's PC.
But I don't feel like going back to the DOS cave walls where we carved command lines for hours with some sabertooth fang...
What next? Configuring by hand IRQ and DMA? Setting jumpers on card plots? For "security" reasons it would be impossible anyway, for we have less and less control on low-level parameters on each new Win release... why not, but now the thing runs for years, out of nowhere, the machines get stuck loop-downloading updates that won't install and we should light back the torches and venture in DOS again, to try 40 different solutions with no garantee?
Flies can try thousands of times to pass through a window different ways, blocked by the glass 'til they die... Wow... That's maybe what Windows ment from the start: we are flies. :D
