I had messed with other people's computers, and with some at universities going way back, but this is the first machine I ever brought home for myself. I paid a princely sum for it.
It was 1996, and I had a computer store put it together for me. It lasted a very long time. It was a 120 MHz Pentium, 8 MB RAM, 28.8 dial-up modem, and a 1.5 GB hard drive. It came with Windows 95 pre-installed. A year or so later it would become a dual-boot with Red Hat Linux.
Over the years it got multiple memory upgrades, multiple larger hard drives, 56k modem, then an Ethernet card.
