TI Model Number - test-drb@ccmp.vtda.org

...
  The "TI-99/4A" was derived from the
following:

              TI:  Texas Instruments, of Course.
              99:  A cute little number based on the "9900"
microprocessor,
...
  which the computer had as the CPU. 
This CPU was thought to be very powerfull for its time.  Was it 16bit,
while most of the others were 8bit?

...
               4:  TI's first model computer - #4 -
sounds cool, heh? 
If it was their first, why #4?  What happened to 1-3?

...
               A:  The enhanced model of the
"TI-99/4", which came out in 1981,
...
  the 99/4 came out around 1978. 
Oh, I never knew there was a 99/4, I only heard of the 99/4A.  Reminds me
of when Atari enhanced 
their ST and came out with the STe.
