Vintage computers are very neat...although I'm more into the professional machines and laptops versus the early home computers such as the IBM PCjr, Tandy TRS-80's, Commodore 64, and TI 99/4A. Very cool Zenith Data Systems laptop...such a big screen on an early machine, and too bad they don't make pop-up drives today!
I used to be really into vintage computers around 6 years ago, but I don't have that much stuff left now. Just boxes of parts, an IBM 5150 with two 5 1/4" floppy drives, "Austin" 486DX (that's in my room now paired with an IBM ProPrinter II...Microsoft Windows 3.1 and MS-DOS 6.2 are the PERFECT pair...boots in 30 seconds!), and two IBM PS/2 model 30's (early 8086 versions with the ISA bus instead of the later Microchannel; one a 720K, 3 1/2" dual-floppy and the other with a "clackety" Seagate 30 MB HDD).
DOS is really fun to mess around with (especially the early versions...I have a copy of version 2.11 for my IBM), and after using Windows 3.1 you will be amazed at how horrible Windows became in the last 10 years. Windows 95 was the absolute worst...EXTREMELY trouble-prone and took me some getting used to. Windows 98 and XP I can tolerate a little better. IMHO, the mistake was where they removed the separate MS-DOS and integrated the two. It loaded a hell of a lot faster with it and didn't hog memory and HDD space like the 95 and later versions do (this is really the only reason we need the multi-gigabyte hard drives...DOS could run on a 360K floppy!). Plus, you had the simplicity and control of the wonderful command prompt interface.
Jason, I can't believe you have to use a DOS emulator for XP, and even then you can't play the early-90's games! How insane on Microsoft's part...
