1.3 Test Diskettes
V1
Be sure to use a known good Vector Graphics Extended CP/M System Diskette
for booting and running any software tests indicated in the manual. Although
users are instructed to include the System Diskette originally supplied with
their Vector 4, it is advisable to load any unverified diskettes into a working
drive and boot from them or verify the directory, prior to using them for
troubleshooting or testing.
General Instructions
If the Vector 4 has been set up as described here, the following
troubleshooting procedures should provide a valid and accurate picture of
potential system malfunctions. At this point, the system should be turned off,
with the cover removed and all connectors (power cord, keyboard cable,
printer or peripheral strips, et cetera) checked for correct positioning and
tight fit.
Next, proceed to Section II, the Troubleshooting Flowchart. Follow the checks
outlined there, while trying to make the reported symptom repeat under the
controlled environment. When the symptom does repeat, refer to the indicated
symptom (isolated by number), against the Symptom Charts which make up
Section III. Section IV gives an exhaustive list of test points used for
checking voltage, wave form, and timing patterns. Refer to Exhibit VI-12,
Vector 4 SBC Component Diagram, for location information on the Vector 4
SBC.
