PI: 400 MHz K6-III+, 256 MB RAM (the maximum possible), ATA hard drive, 66 MHz FSB, Diamond Stealth 3000 3D video card (4 MB RAM). PII: 350 MHz Deschutes CPU, 448 MB RAM (expandable only to 768 MB), ATA hard drive, 100 MHz FSB, Creative Banshee AGP (16 MB RAM). Direct rendering actually works on this first generation AGP card. Bottom line is Trinity is usable on the PI and PII. For sure I would not want to use these systems all day, yet at least Trinity is palatable on these clunkers. :) Although arguably we showed that a PI or PII could suffice as minimum system requirements, real-world observations indicate such claims should be as a sidenote.
IMO, if TDE is usable (although slow) on these machines, these should be the minimum system requirements. Their are called 'minimum' for a reason :) Perhaps after listing them, we could add a statement that says that a P3 is recommended for a better user experience.
