 | | The LSI-11 (1975-ish) was a popular microprocessor implementation of the PDP-11 using the Western Digital MCP1600 microprogrammable CPU, and the architecture influenced the Motorola 68000, NS 320xx, and Zilog Z-8000 microprocessors in particular. |
 | | Like the 68000, the 320xx family consisted of a CPU which was 32-bit internally, and either 32 or 16 (and later 8) bits externally, as indicated by the last two digits. |
 | | Unlike the 68000, the 320xx had eight instead of sixteen 32-bit registers, and they were all general purpose, not split into data and address registers. |
