CZKDKB0

This is an APT compatible version of the KDJ11 memory management diagnostic. It focuses on testing the functionality of the memory management features. The test requires 4 megabytes of QBUS memory to fully test the MMU adder. A subset of the adder is tested if less than 4 megabytes of memory is available (minimum of 28 kbytes). In addition: for testing in QBUS systems with only 18 address bits, a means is provided to skip tests which require 22 bit addresses. This feature is implemented by setting bit 08 in the software switch register (location 176) to a one. Default is to test 22 bit addresses.
