My dad was into electronics, so the first real computers that I used were Commodore Vic20's and 64's. Later, he purchased an 8086 that I spent a fair amount of time using.
When I was in college in 1994, I purchased my own computer. It was a Packard Bell 486-SX25, 4MB of RAM, 170MB hard drive, with a 2x cdrom drive. If I remember correctly, I paid about $1500 for that computer at ABC Warehouse. I remember upgrading that computer to 20MB of RAM, by purchasing a 16MB RAM chip when they dropped below $200 (I paid $199). Also, I remember installing a 730MB western digital hard drive that I got at Sam's Club for the low low price of just $358
