You are not wrong. From the KDJ11-E module user's guide (on BitSavers)
the solder-side of the CD fingers is left unpopulated, but for the +5
and ground pins.

The only PMI compatible option then would be the KTJ11-B UNIBUS
adapter. (You could probably use an MSV11-Q non-PMI memory to fill out
the last 2MB though.)

Best regards,
