とうとうDuemilanove (2009)も型落ちに^^;
まぁ328を挿して使っている分にはDiecimilaも大してかわらんのですが
どうやらUSB-Serial変換部分を例のFTDIからATMega8U2ベースに変わるとか

Arduino Uno
This board will replace the Duemilanove. We decided to be nice to the
non-italians and use a name that was simpler to pronounce and
write. Uno means one in italian and this board for us is the basic
building block of the Arduino product line. We replaced the aging FTDI
chipset with a custom made usb-serial converter built with an Atmel
ATmega8U2 this provides lower latency and doesn’t require to install any
drivers on mac and linux (on windows all you need is a simple .inf
file) more advanced users will be able to reprogram the USB chip to make
the board show up as a variety of USB devices (Keyboards, Mice,
Joysticks, MIDI etc)
ToDo worked their magic also on the board redesigning its graphic
language keeping the form factor that has become an industry standard.
We believe this strong branding will better differentiate us from the
cloners and let customers identify much better the original product.
Finally these boards are fully CE certified with pending FCC certification.

I/Oの割振りに悩んでいるとこ、
Megaを投入しなくてもなんとかしたいけれど、左右独立DCモーターでフォトインタラプタを割込処理させると、モーター制御のPWMが...とか、
やはりISR位はアセンブラでないと...?
取り敢えず、物理的な工作(フォトインタラプタの円盤とか)をすすめよう
でもFTDIでなくなると、ライタにするときに使ってたケーブル、使えないよなぁ石違うし、今度はブートローダーを本体単体で書き込む方法はあるのだろうか？
