Some early DEC gear used it to mean 'microcode processor', but there's no microcode here; if you look in [http://www.bitsavers.org/pdf/fabritek/mp12/400-0227-01_Fabri-Tek_MP12_System_Manual_3ed_Section_2_1974.pdf Section 2], there's a description of the execution of each instruction, and it all seems to be run by a state machine - i.e. hard-wired logic. I guess it just means 'miniature processor'! [[User:Jnc|Jnc]] ([[User talk:Jnc|talk]]) 13:05, 31 July 2024 (CEST)</ins></div></td></tr>
