I don't know--for its time (1976), a 16-bit CPU with hardware 
multiply and divide isn't too shabby.  A bit slow because its 16-word 
register file (relocatable) was kept in main memory (operations 
referencing a register were directed to the appropriate location by a 
pointer registrer called the Workspace Pointer).

Not exciting, true, but there were certainly more boring MPUs out 
there at the time.

TI did make an I2L version of the TMS9900, but the most I was able to 
get from the local TI sales rep was a bunch of datasheets--and no 
samples.  I gathered that the I2L version was reserved for the 
defense industry.

Cheers,
Chuck
