Notes:
-The list accounts for the optionals sections like S-video and the Luma trap. Remove the applicable parts if you don't require some of these options.
-The DC-in socket (U5) is a common barrel type jack. If you don't have a wall mount power supply you can order this multi-plug model (international) : T948-P5P-ND or North American: T980-P5P-ND
SNES Connectors: Last year we found a source for brand new SNES connectors and made a bulk order. I'm selling some to the community for USD$2.00 + shipping. If you're interested send me a PM with your shipping address, I'll give you a final quote including shipping (payable with Paypal). *** Update: No more SNES connectors to sell, sorry. When I find more, I'll let you know. ***
*Important*: At 28Mhz, the ATmega644 is running out of specification and Clay and Ladyada have reported a few units had issues coping with that extra speed. Hence, I strongly recommend you order at least 2 of at once. If something seem weird, it's just easy to just swap the chip to see whats going on.
Cheers,
