Molex housings and pins for the System 80 CPU connectors
Single-sided connectors use 2574-series housings: A1-J1 09-01-7051 (5 pin), A1-J2 09-01-7241 (24), A1-J3 09-01-7171 (17), A1-J5 09-01-7101 (10), A1-J6 09-01-7191 (19), with 2478-series pins 08-52-0072 for 18-20 gauge wire or 2578-series 08-50-0134 for 22-26 gauge (the thinner-wire pin is struck out for the A1-J1 power plug, so use 08-52-0072 there). A1-J4/A3-J1 uses a 4338-series 48-pin flanged housing 09-50-6245 with 4366-series pins 08-03-0304; the 4573-series 08-03-0306 option is struck out in the table, and Gottlieb used 4366 pins on every wire.
