It was actually wrong... 9C8C seems not to be used in the mid 2009 MBP.
My late 08 unibody macbook collector's edition has a 9c8c.

Location: San Francisco ~ MacBook [Aluminum] Owner's Thread
I picked up my $1,600 MacBook tonight at 7p at Stonestown Galleria store in San Francisco. It was their last one, so very lucky! Apple rep had no clue about DisplayPort cable at Stonestown, so I had to educate him and run to Stockton Street store to pick one up!
So, I’m creating a thread where owners can post their experiences.
Comments
Weight -- half-pound weight loss is definitely noticeable compared to previous MacBook.
Chassis -- This is definitely the German ubercar of computing. A total brick, man. THERE HAVE BEEN ISOLATED REPORTS OF LOOSE-FITTING BATTERY COVER PLATES. CHECK THIS THREAD FOR MORE INFO:
https://forums.macrumors.com/threads/584475/; or even better, watch this YouTube video. The edge of the Aluminimum MacBook is not sharp like the white MacBook, so definitely more comfortable.
Display -- The LED screen is noticeably improved over last MacBook. It's nice, evenly lit, with very minor light leakage at bottom. I have no dead or stuck pixels.
UPDATE: SOME USERS REPORT THAT LCD PANELS SUPPLIED BY AU OPTRONICS ARE SUPERIOR TO LG/PHILIPS PANELS. TO SEE WHICH ONE YOU HAVE, FOLLOW THESE INSTRUCTIONS:
CHOOSE “SYSTEM PREFERENCES...” FROM APPLE MENU
CLICK ON “COLOR”
CLICK ON “OPEN PROFILE”
SCROLL DOWN TO ITEM #13 AND CLICK ON IT AND YOU WILL SEE THE SCREEN BELOW:
THE “MODEL” NUMBER CONTAINS THESE CODES:
9C89 = LG Philips
9C8C = AU Optronics
Recommendation: Make sure to increase saturation by choosing television gamma in display preferences. Also, several other threads contain calibrated monitor profiles that may help.
GPU -- Another important improvement is the new Nvidia GeForce 9400M graphics processor (Apple is the first company to ship a computer using the 9400M). Unlike the integrated Intel GMA X3100 graphics in the previous MacBook, the 9400M has its own graphics processing unit (GPU), providing more power than the integrated Intel chip. Like the X3100, the 9400M doesn’t have its own memory, and instead relies on main system RAM. But the Alu MacBook uses fast DDR3 SDRAM and the GPU gets 256MB of RAM, a boost from the 144MB of the X3100.
Trackpad -- Trackpad is very responsive. I love the fact that Jobs solved the two-button trackpad mouse issue, without actually using buttons! SOME PEOPLE SAY THEIR TRACKPAD IS NOT CENTERED AND HAS LESS OF A GAP ON ONE SIDE. CORRECT GAP WIDTH IS ABOUT 1MM ALL AROUND.
SuperDrive -- faster and quieter than previous generation.
Keyboard -- you will grow to like this keyboard; spaced-out keys reduce typing errors; keyboard cover plate resists accidental damage due to spilled drinks. Most importantly, blueberry muffin crumbs can't fall between the cracks.
Speakers -- much louder than MacBook. Finally!
Wi-Fi -- reception is very strong with Time Capsule, and rock steady.
Power -- Battery lasts about 3:30 hours at medium brightness and approximately 2:30 at maximum brightness, with Bluetooth and Wi-Fi on. Keep in mind that the 45-Wh battery is smaller than the one from the original MacBook, which had a 55-Wh capacity. This partly explains the weight savings. RECHARGING BATTERY TAKES VERY LONG. TYPICALLY THREE HOURS FROM 0% TO 100%; WITH TWO HOURS REQUIRED TO GO FROM 50% TO 100%.
