My XT clone has a DTK motherboard.  Unlike the Super K that "you" has,
it is socketed for two banks of 41256 and two of 4164, so it will take
a full 640K on the mainboard.  A note in the User's Manual says:

   Do not use RAM memory on the interface card because its original design
   may not be compatible with the 10 Mhz CPU at access time.  Use memory
   on the mainboard and use 4164 and 41256 access time within 120 ns.

The question may be: is the Zuckerboard certified for 10 Mhz?

>>.....  I had to experiment with the jumpers....

Get the User's Manual and RTFM (Read The Field Manual?).  It might help.
