I'd look at the 16C76 as well.  No need for 33 I/O pins if you are
running the I/O off serial.  I'd suggest the '73A as well, but the
'76 has more modes on the SPI ('73 won't drive the MC145051 AtoD,
but the '76 should).

BTW: I have working code for driving LCD displays (4-bit)... unlike the
Microchip App note code which usually doesn't work.
