Performance. The TI99 was based on the TMS9900 microprocessor, a 16bit design that was originally built to provide a singlechip central processing unit CPU in lowend models of their TI990 minicomputer lineup. The TMS9900 was also suitable for use in a microcomputer, but at that time the rest of the support chips required to build a complete computer were invariably 8bit, and this ...
