I've looked at HC11 vs PIC too... kept coming back to the PIC.
I also looked at the PIC with more IO vs one with less IO with
some latches... the bigger PIC won easily (pin count!).  I have a PIC16C73
based data aquisition board... drives a character LCD and RS232.
I _didn't_ use the on-board AtoD, but used a Motorola 145051 10 bit
chip instead.  I had to do the serial by hand (but the assembler
macro capability is good - I should post the code).  Used the
interrupt on change inputs to aquire ignition timing - interesting
since this feature is buggy on the 16C73.  Picked up a couple
of duty cycles using the capture inputs...
