I loved my 486DX2 66Mhz based IBM PS/1 (2168), which had a whopping 8MB of RAM. Not only did it really enable me to experience the fullness of PC gaming of the era, but it was the first computer I was able to install an internal modem into, and the computer I used to get SLIP dial-in access to the state university mainframe and thus to the Internet (prior I was limited to Prodigy walled garden). It was this computer that let me play early MUDs via telnet, let me play my first graphical MMORPG (Ultima Online), and and introduced me to real visual programming (Visual Basic).
To a significant degree, the 486DX2 was the primary computing platform that created the foundation I needed to learn computing at depth and enabled my later career, and really set many of the formative moments in my life. Thanks Intel, even though you suck now as a shadow of your former self you were a beast in the 90s.
