Description:The TMS9900 COU was the first 16-bit
microprocessor that could effectively
compete in the computer market. In
fact the TMS9900 is a single chip
implementation of the TM Seiries 990
minicomputer CPUs.

The 9900 has a seperate 16 bit address
bus and a 16 bit data bus in a 64 pin
DIP.

The 9980 has an 8 bit data bus and
14 bit addressbus but is otherwise
the same.

The 9940 is a one-chip solution with
onboard memory and real-time clock
circuit.
