My entry was the mentioned 486DX2-66Mhz. Double speed CD-Rom and Sound Blaster. Norton Commander was great, Doom and Pirates Gold where my games of choice.

Also started programming on this one with QBasic and then moved to Turbo Pascal 7 (because I needed a .exe file to be called from autoexec as a password protection vs. my sister which I couldn't do with QBasic :)

Didn't take me long to destroy everything by trying to install some old SUSE-Linux from a floppy disk :D
