I saw a news report about the COCO on the TV show, 
Computer Chronicles.  The report interviewed a user-group that still uses it.  But I think I saw that show 8 years ago, lol.  Atari 800/1600, Commodore 64, Apple, Amiga, DEC--man those were the days.  Now everyone has a PC or Mac and there isn't much romance in it.  Everything's user friendly with a graphical user interface--kinda takes the geekiness out of it.  Sad to say, I don't program for fun anymore  

My PC history. This is fun.  

I remember playing Lemonade and Oregon Trail on the Apple IIe computer in Junior High.  
Then I bought my very own computer in the summer of  1990.  It was a PC-XT running at 4.77 MHz--until my sister showed me there was a turbo switch that could be connected.  Then it ran at 8.54 MHz, woot!   I got it for $300.  It had a 5 1/4" floppy and 1 MB of RAM.   I think that price included the 12" TTL Hercules amber monochrome monitor.  I bought a 20 HD for it for another $100 or so.  My sister was a partner in a computer business and sold it to me.  I later worked for that business in '92 putting computers together in the back.  At that time the 486 was king.  A typical server would be a 486-33 with 16 MB of RAM.  
My next PC was a 386DX-20 MHz.  I dont remember how much RAM it had.  It was either 1, 2 or 4MB.  I was so excited when I bought a color VGA monitor for it (I think the video card was a Trident something or other).  I bought it so that I could play King's Quest V-- a very cool full color adventure game.
Also about this time I got my first sound card.  BIG difference over the PC speaker.  It was a Thunderboard from Sierra On-line, a SoundBlaster compatible that didn't cost as much.  
PC generation #3 was a 486 DX2/66 with 16 MB RAM. I remember buying 16 MB of RAM for around $650.  And I bought a 57MB HD for $250.  Amazing how prices have changed.  Too bad it isn't like that for automobiles.  It was an this PC that I switched from DOS (I think I was running DR DOS 6.0 at the time) to Windows 95 in Aug '95.  I remember loading the beta version-- it took something like 30 1.44 floppy disks.  Around this time I got my first CD-ROM drive.  The video card was a Genoa Phantom Visa Local Bus.
#4 was a Pentium 120 MHz with 32MB RAM.  I bought a Samsung 17GLsi monitor for $800 in '96. Still use it to this day.  Got my first 1GB hard drive around this time.  Then later a 4GB.  Diamond Stealth 3D-2000 video card.  
#5 was a Celeron 466MHz, 128MB RAM, ATI Xpert '98 video card, bought in '99.  
#6 was an Athlon 1.6 GHz, 256MB RAM, 20GB HD, Nvidia GeForce 2, purchased in '01.
#7 is my current PC, an Athlon XP 2400+, 256MB RAM, 40 GB HD, GeForce 4, includes DVD-ROM and CD-RW.  But these stats fluxuate as I periodically swap parts for work.
