A Wealth of Information From a Guy Whose Been Working With this Stuff since 1997, when it was just considered "Old Crap"
The word "Retro" today is thrown around like a ragdoll in a angry German Shepard's mouth. See, it's not even that new of a concept, but not that old of one either. The whole concept of nostalgia and retro has been around as long as humankind, but never became a real "scene" of sorts until the Punk Rockers and New Wavers in the late 70's and early 80's started to drive around in gussied up 50's cars sporting greaser hairdo's and playing music that while new had some reminiscent elements of stuff from the 50's and 60's. Digital Nostialgia was born in the early 1990's, and I was born 10 years too late, so of course, I grew up WITH it, because I was immersed in the world of bored and skint broke college students as a pre-teen in the mid 1990's. Before PC's, I was collecting Atari 2600 and NES Games when you could buy the whole kit-n-kaboodle for $10 at any local thrift shop USA ~ before the days of clickbait, fraudulent game auctions, and $900 30 year old 486s on e-bay.

Here I'm going to talk about important BASIC things like: how to store your collection (and not piss your spouse/parents off), just how much does having a "Marshall Stack" of pre-Pentium PC's actually affect your Electric Bill (read: not as much as you think), how many actual old as crap beige boxes you need to cover your collection of questionably obtained software (j/k), what kind of machine you want/need, the reasons why limey lunatics like myself would be willing to fill our house with a pile of disused PC's from the Regan/Bush/Clinton administration years, and when you might want to consider using emulation or getting an old as dirt laptop computer instead.
