Jump to navigationJump to search
The M930 UNIBUS terminator is a terminator for the UNIBUS; it provides the first two functions of a UNIBUS terminator (termination and pullups). The M930 is a dual format card, intended for use in the two top (AB) sections of a MUD slot, or in a UNIBUS in/out slot.
The originals used individual resistors (as shown to the right); later ones used resistor networks in DIP packages.
