There are many one-chip CPU's such as the 6511, 68701, 8748, etc. that have
a familiar processor as their core but also have various peripherals, timers, 
memories, and so on.

I've been using the 68701, it has a serial port you can read your data in with,
and has four parallel ports you can use to control a display (even an un-
encoded seven-segment one--just write a program), and some internal RAM and 
EPROM. The processor is a 6800, which has an easy instruction set to learn.

Your display unit would be basically one chip, with driving transistors or
something for the display, if needed.
