The TMS9900 architecture lives on in TI's MSP430 line of MCUs, and they're everywhere. You probably won't get through today without interacting with a bunch of things that have MSP430s inside.

"Like many processor designs, the 9900 didn’t die, it provided the basis of TI’s current 16-bit MCU line, the MSP430 series. The MSP430s instruction set is heavily influenced by the 9900 and largely retains its memory architecture and orthogonal instructions."
