"Finally, there's a 32-bit microprocessor that gives you any UNIX version you want, and all the development tools you need."

Advert from National Semiconductor ("We're doing it") for the Series 32000. ("The SuperMini on a Chip.")

"the only 32-bit family complete with memory management, floating point, timing, interrupt and DMA"
