Recently some changes have been made to the assembly of Deluxe NT960 hosts. Here is a list of
changes:

-The battery, the trim capacitor, and some other parts are no longer installed.
-The jumper locations on boards SN:1747 <-> 1771 are now occupied.


Here is why these changes have occurred.

-The removed items provided the deluxe hosts with some added features which are not used in
the normal operation of the NT960. To lower the cost of a deluxe host, the battery the trim
capacitor and the other parts have been removed.

-Also the trace locations for J17 & J18 were needed to be cut on deluxe hosts. This is
no longer required, but on some NT960 Deluxe hosts, the traces for J17 & J18 were cut. So
jumpers had to be installed to reconnect the traces on boards SN: 1747 <--> 1771.


Without the jumpers on the boards SN:1747 <-> 1771, the NT960 will not function properly. For
example the ntload.exe (DOS) program will not function correctly and will report erroneous
results.


Note: None of this applies to standard hosts. All other NT960 Deluxe Hosts do not require these
jumpers and will be unoccupied.
