You've mentioned this a couple of times.

Are you confusing this with the serial CRU I/O scheme TI computers used?
I double-checked and the 960,980 and 990 minicomputers are all 16 bit parallel machines.

The 9980/1 and 9995 had an 8 bit memory bus but internally are 16.

I double-checked, and the TMS9900 has a 16 bit ALU (page 6 in
TMS_9900_Microprocessor_Data_Manual_May76.pdf on bitsavers)
