Has pictures and descriptions of old computers - including such favourites (not!) as the TRS-80 and VIC 20. Personally, I miss my Commodore 64.
Hey...he doesn't have a Commodore 64 yet!

My dad bought one in 1988. Dual 5.25" floppy drives, no hard drive and green screen (don't remember the technical term for it). We also had a dot matrix printer. You had to put in a boot floppy, and switch out floppies with different programs. I did a few of my junior and senior year essays on that computer, using Wordperfect 4.0. Dad continued to use this computer...til 1999. He refused to get another computer for 11 years, because the Commodore did his Lotus spreadsheets perfectly well...thank you! He finally broke down that year and bought a CompUSA PC with a P-III 500 mhz processor, 20 gig HD, and 128 MB of RAM. He is now on his second PC, a Dell with a P-IV 2.4 Ghz processor, 40 gig HD, 512 MB RAM.
I didn't know much about computers, and didn't own a PC at all until 1998. I started dating a guy who was a computer tech, and he gave me an old Toshiba laptop. Specs: 486 processor, 256 MB HD, 16 MB RAM, 7" color monitor with 640x480 resolution. No sound card. And a card modem, running at 33.5 Kbps. It used to run Windows 3.11, but he installed Windows 95 and Office 95.
I soon got tired of not being able to surf the Net for more than a half-hour (the cache totally overwhelmed the meager memory space), and bought my first PC the following year. It was a generic Digitech, with an AMD-2 350 mhz processor, 7 gig hard drive, and 64 MB RAM. I started playing with upgrades, and pretty much upgraded this PC to death. I switched the processor to an AMD-2 500 mhz (didn't really notice an increase in speed), added another 64 MB of RAM, and installed a 16 MB videocard (as opposed to the onboard soundcard). That is pretty much what I do to my PCs nowadays; I throw in more stuff and see if it sticks.
My current PCs are a Sony Viao (P-IV 1.8 ghz, 512 MB RAM, 80 GB hard drive, 64 MB All-in-Wonder video card, DVD-R drive) and an upgraded Dell (P-IV 2.6 ghz, 1 GB RAM, 300 GB hard drive, 128 MB All-in-Wonder video card, DVD+R drive).
