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. iv 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
