Duplication Interface B Common Shadow Circuit and from control carrier A to test
the Duplication Interface A Common Shadow Circuit.
Common Shadow Circuit Address Decoder Test
(#284)
This test verifies the operation of the shadow address decoder portion of the
common shadow circuit. Software writes data into memory locations that should
not be shadowed. The maintenance register of the common shadow circuit is
examined to determine if the shadow address decoder permitted the write to be
shadowed. The test fails if the writes were shadowed. This test is run only when

NO
BOARD
The Duplication Interface circuit pack has failed to handshake with
either the active Maintenance/Tape Processor (in the case of
Duplication Interface circuit pack A) or from Duplication Interface circuit
pack A (in the case of Duplication Interface circuit pack B).
1. Refer to NO BOARD description for the Duplication Interface Circuit
Pack Status Query Test (#315) in DUPINT.
PASS Part of the Common Shadow Circuit is operating properly; however,
Tests #284 and #285 must pass before the Common Shadow Circuit on
this Duplication Interface circuit pack is considered sane.
