I think that the Field Guide is a bit confusing regarding the Unibus
situation. Despite what the OPTION column reads there, the UDA50-A is only
the controller and not the Interface (which is listed on the next row/entry
as "UDA52"), so the M7485 +M7486 always are paired -- just as are the M7161
+ M7162.
The Option/Module list actually describes the UDA50-A like this:
UNIBUS DISK ADAPTOR,32KB BUFFER (M7485-YA,M7486)
The UDA50 apparently only has an 8KB buffer.

OK,
I believe these are the options:
For UNIBUS: UDA50 (M7161 + M7162)
UDA50-A (M7485)
UDA52 (M7486)
For QBUS: KDA50-Q (M7164 + M7165)
For VAXBI: KDB50 (T1002 + T1003)
For XMI: KDM70 (T2022 + T2023)

I've never heard of a KDB50-Q. The Q-Bus SDI
controller is the
KDA50-Q, consisting of two boards (M7164 and M7165).
My mistake, yes I meant KDB50-Q.
