 |
|
The TMS9980 was a 40 pin version of the 9900 CPU (itself based on the TI 990 mainframe) released in 1978.
These are some pretty rare and early examples
The 9980 was a 40 pin DIP version of the 9900 with an 8-bit data bus and 14 bit address bus operating at 2.5MHz. The 9980 continued to use 3 power supplies, (-5V, 5V and 12V). The main advantage of the 9980 was the reduced pin count and thus reduced cost. In 1978 a 9980 cost $30 while a TMS9900 cost $70.
