Of course, the most famous early 16 bit micro has to be TI's 9900. And the second most famous might well be Intel's 8086. And I think there are good stories to be linked about both of those. ("The Inside Story of Texas Instruments’ Biggest Blunder: The TMS9900 Microprocessor", Interview with Stephen Morse, the (relatively inexperienced) 8086 architect)

But also!
Panafacom MN1610, the "first Japanese 16-bit microprocessor, April 1975. Architecture is based on their mini computer; 33 instructions (one word); 5 general register; 64K words memory space; 256 words I/O space; 3 level interrupt; register to register operation time 3 micro seconds; -3V, +5V, +12 V power supply" (Ref)

Wikipedia says this:
Quote:
Around 1978, several 16-bit CPUs became available. Examples included the Data General mN601, Fairchild's 9440, the Ferranti F100-L, the General Instrument CP1600 and CP1610, the National Semiconductor INS8900, Panafacom's MN1610,[5] Texas Instruments' TMS9900, and, most notably, the Intel 8086. These new processors were expensive to incorporate in personal computers, as they used a 16-bit data bus and needed rare (and thus expensive) 16-bit peripheral and support chips.
