The TI was the first commercially available 16-bit to the consumer.
The 9900 is a 16-bit microprocessor, with separate address and data
bus. 16-bit address bus (MSB is used to determine even or odd byte)
allowing it to address 64k, byte addressable. 16-bit data bus. In the
99/4A, this is muxed to an 8-bit data bus outside the console for use
with 8-bit peripherals (not unlike the first PCs - in this case more
like an 8086 than an 8088 which was 8-bit at the processor
connection.)
The instruction set has 16-bit registers and hardware multiply/divide
(unsigned).
