LIST OF EFFECTIVE PAGES I
The List of Effective Paees IIives the date of the current edition and of any pages changed in updates to that edition.
Within the manual, any page changed since the iast edition Is indicated by printing the date the changes were made
on the bottom of the page. Changes are marked with a vertical bar In the margin. If an update is incorporated when an
edition II reprinted, these bars are removed but the dates remain.

IPRINTING HISTORY
New editions are complete revisions of the DWlual. Update packqes, which are Issued between editions, contain
additional and replacement pages to be merged Into the DWlual by the customer. The dlte of the title page of the
DWlual changes only when a new edition II pUblished. When an edition II reprinted, all the prior updates to the edition
are Incorporated.

The HP 3034lA Interface Hodule Hardware Self-Test is a CPU ROf.1-
resident, microcode diagnostic that verifies correct operation of
the Interface Module's hardware. The self-test can be initiated
either by issuing the the Initiate Self test (SLFT) instruction
from software to the Interface Module's Intermodule Bus Adapter
(IMBA) PCA or by manually actuating the Bus Interface Controller
(BIC) PCA's CPU TEST Switch Sl. Switch Sl is located at center
left on the front edge of the SIC PCA.
The results of the self-test are stored in the computer system's
SLFT "mailbox" memory location MB2 and displayed by 10 LED's (A
thru I and "*") located on the left-front edge of the BIC PCA.
Termination of the self-test is indicated by the BIC PCA's "*"
LED being cleared (off) and the busy/wait flag (bit 0) in "mail-
box" memory location MB4 being set. The octal value (error code)
contained in MB2 or indicated by A thru I LED's indentify which
portion of the self-test that failed as listed in the following
tables. It should be noted that the error codes contained in the
second table pertain to specific Control Store ROM chips located
on the Processor PCA.
If the self-test is initiated with no peripheral devices attached
to the HP-IB, successful test completion is indicated by %74 in
memory location MB2 and %740 indicated by the A thru I LED's. If
the self-test is initiated with no cold-load device attached to
the HP-IB (e.g., HP 2680A only), successful test completion is
indicated by %75 in MB2 and %750 indicated by the LED's. If the
self-test is initiated with a cold-load device attached to the
HP-IB (e.g., HP7976A), successful test completion is indicated by
%00 in MB2 and %000 indicated by the LED's.
Note
The BIC LED's will momentarily flash error codes %740
and %750 before remaining lit to indicate that a hard
error does not exist and to serve as a warning that a
particular device i~ not attached to the HP-IB.
