TMS 440 SH-3 7708 Microprocessor Support

Diagrams and Circuit Board Illustrations

This section contains the troubleshooting procedures, block diagrams, circuit board
illustrations, component locator tables, waveform illustrations, and schematic diagrams.

Symbols

Graphic symbols and class designation letters are based on ANSI Standard Y32.2-1975.
Abbreviations are based on ANSI Y1.1-1972.

Logic symbology is based on ANSI/IEEE Standard 91-1984 in terms of positive logic.
Logic symbols depict the logic function performed and can differ from the manufacturer’s
data.

The tilde (~) preceding a signal name indicates that the signal performs its intended
function when in the low state.

Other standards used in the preparation of diagrams by Tektronix, Inc., include the
following:

H

Tektronix Standard 062-2476 Symbols and Practices for Schematic Drafting

H

ANSI Y14.159-1971 Interconnection Diagrams

H

ANSI Y32.16-1975 Reference Designations for Electronic Equipment

H

MIL-HDBK-63038-1A Military Standard Technical Manual Writing Handbook

Component Values

Electrical components shown on the diagrams are in the following units unless noted
otherwise:

Capacitors:

Values one or greater are in picofarads (pF).
Values less than one are in microfarads (

m

F).

Resistors:

Values are in Ohms (

W

).

Graphic Items and Special Symbols Used in This Manual

Each assembly in the instrument is assigned an assembly number (for example A5). The
assembly number appears in the title on the diagram, in the lookup table for the schematic
diagram, and corresponding component locator illustration. The Replaceable Electrical
Parts list is arranged by assembly in numerical sequence; the components are listed by
component number.

Component Locator Diagrams

The schematic diagram and circuit board component location illustrations have grids
marked on them. The component lookup tables refer to these grids to help you locate a
component. The circuit board illustration appears only once; its lookup table lists the
diagram number of all diagrams on which the circuitry appears.

Some of the circuit board component location illustrations are expanded and divided into
several parts to make it easier for you to locate small components. To determine which
part of the whole locator diagram you are looking at, refer to the small locator key shown
below.  The gray block, within the larger circuit board outline, shows where that part fits
in the whole locator diagram. Each part in the key is labeled with an identifying letter that
appears in the figure titles under component locator diagrams.
