8–1 INTRODUCTION
The following paragraphs describe the two software diagnostics programs used to localize fault areas on pc boards in
card slots A3 through A6. These cards are the A3 MST board, A4 Scan Converter Controller, A5 Frame Memory, and
A6 VDO board.
8–2 SERVICE SOFTWARE
There are two service software operating modes: SS (Service Software Program) and SDP (Service Diagnostics
Program). The SDP program tests MST CPU memory ICs on the MST Board. The SS Program tests memory ICs on
the other digital pc boards.

response, SERVICE will appear on the second line of the USER NAME area. Now the Service Software routines can
be accessed by means of keyboard entries.
Note

that function, do not type it out. For example, <CONTROL> and <ENTER> are keys named
