2003993-061, COMPUTER ASSEMBLY







The sub-assembly hierarchy of AGC p/n 2003993-061 is listed below.  Minor sub-assemblies and individual components that appear in the drawings but are not listed below may appear in our master engineering-drawing index.

2003026-031, CURRENT SWITCH MODULE B11

2003982-021 or -031, SENSE AMPLIFIER MODULE, ERASABLE MEMORY B13

2003027-031, STRAND SELECT MODULE B16-17

2003070-031, INTERFACE MODULE A25-26

2003067-041, INTERFACE MODULE A27-29

2003981-021 OR -031, SENSE AMPLIFIER MODULE, FIXED MEMORY B14

2003892-011, POWER SUPPLY MODULE A30-31

2003121-xxx, LOGIC MODULE A1-A24

Note:  For logic modules A1-A24, AGC assembly 2003993-041 allows the use of either assembly 2003121 (this section) or assembly 2003888 (next section).  Unfortunately, with the present state of the drawing collection, we do not have a complete set of drawings for either alternative.  Each of the two alternatives is presented in as complete a state as possible.

Note:  The numbering of the configurations in drawing 2003121 is not consistent between drawings 2003121 and its child drawing 2003086.  The former indicates a gap between configurations -171 and -251, while the latter indicates no gap (i.e., configuration -181 follows -171).  This discrepancy persists in all available revisions of both drawings.  However, one of them is in error.  Here, we follow the convention in 2003121, and preserve the gap.

2003888-xxx, LOGIC MODULE A1-A24

Note:  For logic modules A1-A24, AGC assembly 2003200 allows the use of either assembly 2003121 (preceding section) or assembly 2003888 (this section).  We do not presently have a copy of any revision of drawing 2003888.  However, it is thought from indirect evidence that at some point in the 2003888 drawing tree, drawing 1006395 is called out.  The purpose of 1006395, in turn, is to call out the schematic diagrams for the logic modules.  Our only available revision of 1006395 is rev "-", which indicates that each schematic diagram, in turn, is also rev "-".  Since this seems unlikely, below we use the latest revisions of the schematics currently available to us.
