microcontrollers slightly more powerful than a pic?

[Chad]

The 68HC08 is Motorola's latest and greatest chip.  It's an 8 bit 
microcontroller that is very powerful, but external addressing might be an 
issue.  If you're looking to address external memory, the HC11 is the next 
family to look at.  There is a little bit of external circuitry to 
de-multiplex the addressing with this chip, but it can be done pretty 
easily.  This guy is a little expensive, but he does have a couple of 
decent eval boards and sells individual chips as well:

is the easiest to hook up external memory to, it requires no external 
demultiplexing circuitry.  I've used this for a 512K data acquisition 
system before, very easy to use.  Of course, these are quite a big step 
above a PIC......
