Every keyboard built in the last 3 years uses an 8048 or 8049 single
chip micro, or its EPROM version the 8748/8749.  They must cost like $1
or less and they're pretty reasonable little beasts if you don't have
much of a job to do, e.g. like polling a bunch of switches and sending
the transitions down a serial line bit-by-bit, pretending to be a UART.
