Unfortunately I was a little too young to experience it properly but I do remember my dad bringing home a 486 DX2 66 and messing around with config.sys and autoexec.bat. I'm sure the CPU was made by Cryix.
Not long after he bought home a floppy disk containing a shareware version of "something called Duke Nukem", god did that blow me away at the time.
As a software engineer it pains me to hear 'architects' shouting "oh just give the JVM a 2GB heap, that will be enough". They should learn proper memory management, like they would have had to back in the day!
