Diagnostic Test 50 (Onboard Dual-Port Direct-Access Storage [DPR] Test)
Parameter A = 0, 3, or 4.
This test permits the dual-port direct-access storage (DPR) t o be checked out from
the other side. The test performs a walking ones and zeros test in a way that does
not destroy data. All of the storage may be checked with the exception of the main
interrupt location.
Diagnostic Test 51 (Offboard Dual-Port Direct-Access Storage [DPR] Test)
Parameter A = 0, 4,or 6.
This test permits the dual-port direct-access storage (DPR) t o be checked out from
the main side. The test performs a walking ones and zeros test in a way that does
not destroy data. All of the storage may be checked with the exception of the subor-
dinate interrupt location.
Diagnostic Test 52 (Dual-Port Direct-Access Storage [DPR] Test)
Parameter
A = 0, 3, or 4.
This test checks how the dual-port direct-access storage (DPR) operates when read
and write commands are received at the same time.
Diagnostic Test 53 (Subordinate Dual-Port Direct-Access Storage [DPR] Interrupt
Test)
Parameter A
=
0, 4, or 6.
This test verifies the ability of the dual-port direct-access storage (DPR) to operate
with interruptions.
