Engineering Drawings; Drawing Terminology - Digital Equipment PDP-10 Manual

CHAPTER 7
ENGINEERING DRAWINGS
This chapter contains a list of the engineering drawings supplied with the BA10 system. The
engineering drawings are located in Volume IV of the Peripheral Device Engineering Drawing Set.
Should any discrepancy exist between the drawings in this manual and those supplied with the equipment,
assume the latter drawings to be correct. Module, power supply, and power control panel schematics
are contained in Volume III of the PDP-lO Maintenance Manual.
Refer to Tables 7-1,7-2, 7-3 and 7-4 for the associated drawing numbers and titles.
7.1 DRAWING TERMINOLOGY
The engineering drawing numbers for the BA10 system contain six fields of information,
separated by hyphens. A typical example of a drawing number is shown below:
D
BS
CR10
Drawing Size
I
Drawing Code
Option Number
o
IOCB
B
Revision
Indicator
Drawing Title Abbreviation
Manufacturing Variation
The drawing size, option number, and the drawing title abbreviation are self-explanatory. The
manufacturing variation letter identifies the variation that the drawings reflect. For example: 0 reflects
drawings applicable to all variations; A reflects the 60 Hz equipment; etc. The drawing code identifies
the type of drawing. A list of the common drawing codes follows.
BS - Block Schematic or Logic Diagram
CL - Cable List
CS - Circuit Schematic
FD - Flow Diagram
IC - Interconnection Drawing
KS - Key Sheet
MU - Module Utilization
RS - Replacement Schematic
SD - System Diagram
PL - Parts List
