Go for the STM32F4, much faster and capable that any dsPIC will ever be.
They look nice, and the inputs are 5V tolerant, and that is important to me. If the output is 3.3V that is near ttl levels, and it is not an issue, the biggest issue is the 5V input tolerance.
None of the STM32F4 seems to be available in dip packages, but I could probably find an adapter board on ebay.
I don't like using dev boards in my projects, because I am always trying to integrate the circuits on a smallest possible surface, so that I don't end up with a bulky contraption.
"8080/6800 modes", oh, I like that a lot, I have lots of such peripherals.
Can the LQFP be soldered on a TQFP layout?

Also how it is programed?
Also are there any other chips, maybe some older chips?
