I'm afraid that the only reason to make these MCU's is to use them in
consumer products. The MSP430 is used in electricity meters. Th PIC has
been used in rice cookers, bread makers, computer mouses. One of the common
ABS systems used an 8051 with a PIC as a "safety shell" processor.
Recently, most embedded processors have been "targeted" at either the
telecomms or automotive market.
Many of the ones you can't identify will be mask programmed versions of the
processors you're familiar with, with the OEM manufacturer's part number on
them (even the bump packaged ones).
Keep pulling things apart and you'll eventually find some of your friends.
