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!
DEC also used the DEC DC005 for the data and address lines on QBUS cards.
The Signetics code is C2324N
DEC also used the DC005 (8 pcs) for address / data interface on the M8739 KLESI
(Aztec/RC25)
UNIBUS interface card. DC013's were used for the NPR/NPG and BR/BG logic.
