I miss the good old days, playing Wing Commander and Red Baron on my 386 DX/40, 8MB of Ram, Original Soundblaster Card, and a 1MB SVGA graphics card. (S3, I think).
And, remember the good old copy protection the games used to have? They either had a "Code Wheel", or the classic: "What is word 3, of Paragraph 2, on Page 48?" (Refering to the game manual.)
