Great info, asterick. I didn't even look at the other chips- I just assumed it was a standard 2 glop top setup. At least one of them has to be the CPU, right? Wonder what the other one is...
<edit> Yes, at least one glop top is the CPU
Mine doesn't even have a 2nd glop top. It may very well depend on the shipment if you have a glop top rom, or even your model. If there are 3 version, it's very possible that they could have only done flash in the 50 model to save money. Either way, I'll get back to you guys with more information.
I decided to include a photo from my board... this was using my roommate's cheap camera... which is to say it doesn't have the best quality
There are 3 'IC's on the board. there is a small, 16-PIN SMT chip on the top right, 72HC4053D which is a logic gate of some king, may also be used to drive the crystals to produce clock signals. The glop-top is the supposed NOAC, and the bottom is a 32Mb flash chip by Micron, 90ns access speed: Part number 29LV329BTC-90. Note that this flash is rather... slow. it can only be read at 1/2 the speed of the fastest oscillator, which normally isn't an issue (considering the NES access timing)
the Two oscillators are: 21.474424 (NTSC Color burst x6, this is the standard speed for a NES crystal. It's interally divided by 12 to produce the CPU clock, the video is actually double clocked out using a 12-bit ring counter to produce 12 colors and 2 'white' palettes at 4 lum levels. The clock signal is applied to the A0 on a 12x16 rom. 'Kevtris' has some good info on this if you want to look it up). The other oscillator is 26.60712. This crystal presents no real information to me, it may be used for PAL timing, if the thing is biregional. That, however, is highly unlikely (it's cheaper to build 2 models).
26.601714 = PAL color burst x12 (close!)
The rest is just your standard run of the mill off the shelf transistors, caps and resistors. I believe there is a 3.3v regulator near the top under a barrel package cap (labled U4).
The LCD has no part number. It's most likely some cheap no-controller jobber. No real way to tell without being able to scope it, and unfortunately, ours in is the shop.
