Description
You are bidding on 1 of a Super Rare IBM 9121 Super Computer mainframe TCM module from a IBM ES/9000 series computer. Module is 6.5 x 5.75 x 1.0 inch tall, gold pins and silver solder aluminum heat sink, with 2772 pins, Date 9420, inside are 121 chips on a substrate, each chip about 8 mm suare, pulled from good systems. """ UNIT HAS NOT BEEN OPENED UP, Photo is for Referance""" .MORE INFO:This paper discusses the problems associated with obtaining adequate test coverage from random self-test for thermal conduction modules (TCMs) in the air-cooled IBM Enterprise System/9000™ Type 9121 processors. Each 9121 TCM contains approximately a quarter of a million circuits. The present complexity of the TCMs made previous testing methods such as chip-in-place (CIP) testing inviable. The solution was to apply self-test techniques to the 9121 TCMs during the manufacturing process. Analytical and simulation techniques were used to predict the random-pattern testability of the TCMs. The results of the self-test process for the five distinct 9121 processor TCMs are presented. Methods of identifying and modifying random-pattern-resistant logic structures are discussed. It is also proposed that a hybrid approach combining random self-test with deterministic test generation can be used to enhance testability.The IBM Enterprise System/9000™ Type 9121 air-cooled processor achieves, with the same or reduced physical floor space and power levels, a performance level equal to or greater than those of previous IBM processors. This performance level was attained by a combination of design innovations: a new air-cooled thermal conduction module (TCM), integration of bipolar and CMOS technology in this TCM, the design and implementation of a differential current switch bipolar circuit family, integrated programmable memory subsystem design, and extensive use of VLSI technology. The result of these innovations was a 15-ns-cycle air-cooled machine. The salient features and an overview of the machine design are presented.
