Inside
Opening the Acer n50 is quite easy. Just remove the four screws on the back and take the back off by pressing the sides in the upper part of the case. To take the mainboard out of the case you have to remove another two screws. Be carefull as the mainboard is still attached to the front panel with the LCD connector. Also the hold switch seems to break easily.
Here are some photos of an Acer n50 Premium by ![[MAILTO]](/moin/handhelds/img/moin-email.png){kind=small}
PedroCoke. The relevant chips are numbered and you can look up the information below. The few differences to the n50 Standard are also noted below (the RAM and the processor).

Notes
I can't guarantee that the info above is 100% correct, some markings are really small and really hard to read even with a magnifying glass. If someone needs to see a specific part I can post a pic, let me know(mail below).

Great images! I removed my useless old ones 
The list should be OK, I checked it on my Acer n50 Standard. I couldn't find any difference besides the RAM and the processor. Could you try to read what the holographic looking chip to the left of (1) in the image says? It's really small and you can only see it if you hold the board the right angle...
-- WolfgangKempin 2006-06-17 14:57:25
I couldn't find any marking on the chip, I used a magnifying glass and a table lamp and tried at various angles. =(
Could be just me, and it is late so... I'll try this again some other time... Also added some smaller images to improve the page ease-of-use (kinda useless).

Got it: It reads "MARVELL / W8305-B2 / 508ALPS", so it's a 88W8305 wireless chip... It seems there's no driver for it yet and Marvell doesn't even provide any information on it 
(some info from a device with a similar chip) I guess we'll have to do some reverse engineering...
-- WolfgangKempin 2006-06-20 21:36:37
Because Marvell joined the "One Laptop per Child"-Initiative, we might get a driver supporting our chip, too. Development for a Linux driver has just started (devel log, mailing list).
