581 Series


581 Series chips have been used for Soviet "Electronica 60"computer.
These chips are combined in a processors named "M1" and"M2" - analogue of DEC/WD CP-1600.

M1 is a set of following ICs:

581IK1 (581ИК1) - RALU (register ALU) - analogue of CP1611 Data chip

581IK2 (581ИК2) - Control IC - analogue of CP1621 Control chip

581RU1 (581РУ1), 581RU2 (581РУ2) - Microcode ROM - analogue of CP1631 Microcode ROM (MICROM)


M2 is a same set as M1 + 581RU3 (581РУ3) - Microcode ROM w/ additional commands
