EKBEE1: 11/70 MEMORY MANAGEMENT DIAGNOSTIC
------------------------------------------
From the [PDP-11 Diagnostic Handbook (1988)](http://archive.pcjs.org/pubs/dec/pdp11/diags/PDP11_DiagnosticHandbook_1988.pdf),
p. 1-10:
11/70 MEMORY MANAGEMENT TEST
ABSTRACT:
This program was designed using a "BOTTOM UP" approach starting with the smallest segment of MEMORY MANAGEMMENT
logic and building up to cover all the logic. The program begins by testing some of the internal CPU data and
address path and address detection logic, then works outward through the MEM. MANAGEMENT registers. It is assumed
that both the CPU and the CACHE have been tested, or are known to be good.
OPERATING PROCEDURES:
Set the switch register by <CONTROL P>
CON = xxxxxxWZ
(W = deposit xxxxxx into console switch register)
(R = read and type console switch settings / CON = R)
(Z = switch console terminal back to program)
.R EKBEEI
SWITCH SETTINGS
SW15 = 1 halt on error
SW14 = 1 loop on current test
SW13 = 1 inhibit all error typeouts
SW12 = 1 inhibit trace trapping
SW11 = 1 inhibit iterations
SW10 = 1 ring bell on error
SW09 = 1 loop on error
SW08 = 1 loop on test in SWR < 06:00>
SW07 = 1 inhibit multiple error typeouts
SW06 = 1 selects subtest

The closest we have to a source code listing of the EKBEE1 diagnostic comes from some
[scanned microfiche](http://archive.pcjs.org/pubs/dec/pdp11/diags/AC-7975E-MC_CEKBEE0_1170_MEM_MGMT_May80.pdf)

One of the last tests within the diagnostic to pass in PDPjs was "TEST 122: KT BEND", which appears on p. 208 of
the PDF (p. 199 of the source code listing):
;;***************************************************************
;*TEST 122 KT BEND
;*
;* THIS TEST ENSURES THAT TMCE KT BEND GOES LOW ON AN ODD
;* ADDRESS ERROR, SL RED, AND NEXM. THIS IS DONE BY EXECUTING
;* AN INSTRUCTION FOR EACH Of THESE THESE CASES THAT ALSO
;* CAUSES A KT ABORT. THE ABORT SHOULD NOT BE HONORED.
;*
;* NOTE: ON A KB11-E OR KB11-EM THE KT ABORT SHOULD BE HONORED OVER A
;* NEXM TRAP. IF THIS IS A KB11-E/EM THEN THIS FEATURE IS TESTED.
