Do you or someone have a list of all the Unibus bus
chips ?
I have seen the following bus interface chips used on DEC UNIBUS boards:
Drivers:
8881 - Sprague, Signetics - Quad NAND
Receivers:
380 - Signetics - Quad NOR
314 - Signetics - 7-input NOR
8815 - Signetics - 4-input NOR
8837 - National Semi - Hex receiver (aka Signetics N8T37)
8640 - National Semi - Quad NOR
Transceivers:
8641 - National Semi - Quad transceiver
The actal complete part number can vary depending on the manufacturer; e.g.
the 8641's are usually DS8641N, from NatSemi, and the 380's are usually
SP380A's or SP380N's. Where the basic number is not included (as with the
8T37 for the 8837) I have given it.
The following chips have been used by DEC to interface to the QBUS, and
I have seen many of the above chips (e.g. 8641's) used there too, so I
think chips seen on one bus could be used on the other:
Drivers:
7439 - Various - Quad NAND
Transceivers:
2908 - AMD - Quad latching transceiver with tri-state output
I _believe_ the following chips are also usable as UNIBUS/QBUS interface
chips, but I'm not sure if I've seen one used there:
Transceivers:
8836 - National Semi - Quad NOR
8838 - National Semi - Quad transceiver (aka Signetics N8T38)
Quite a zoo!
