Expanding to 512k was a pretty big deal back then

And under 10K too, what a deal!!  

Ahh god old times

show them a PC from today and they would die, then tell them that it cost less than ~$1,000 USD

I'll show them my lappy. Won't that freak 'em out. Dual core, 2 gigahertz, 300 gig HDD, 4 gigs of ram and that's small. And it even has a pretty UI.

Hey, our low range PCs would be like magic back then.  I cut my teeth on an Apple\\+, and trash 80's (TSr, TRS?), commodores, etc. were also circulating.  IBM was saying, mainframes (building sized computers) were the future.  Apples?  = no future.  /// Now.  Wow.  The mars rovers use a thumb drive (flash drive) for its programming storage.  One of our current cast off PCs has more computing power than all the computers used by NASA for the Apollo moon landing missions.  Future?  bio based PCs, web integration, clouds, chips, Holo-vids, holo games, smell-o vision.  I'm beginning to understand how the old folks felt when they saw their first 'horseless carriage.' 

Wow.  Low cost?  According to the U.S. Bureau of Labor Statistics, $10k in 1980 (when the Z-2H was introduced) is worth $28,219.78 in 2013 dollars.

I'd like to have that much to spend on a computer.  If I did, I'd use it to take a vacation instead.
