SECTION 8
PROBLEM ISOLATION
8.1 Introduction
In the unlikely event an apparent maltunction should occur with
the SUPER STAR, it will be necessary to isolate the problem to a
specitic piece ot hardware or sottware. Otten, determining
whether a problem is hardware or sottware-oriented is an easy
task. In tact, ,once a sottware package is established and has
been working in a system, it can't "tail". It can be accidently
erased, or moditied, but the chances that a tailure in the
sottware has sUddenly occured is too remote to even consider as a
possible symptom.
8.2 The First Step
When isolating a problem with the SUPER STAR, your tirst task
should be to absolutely remove any possibility ot a "pilot
error", (i.e., you did not accidently erase a tile or mOdity some
sottware, etc.). To prove that this did not happen, reset or
"Shut-down" the system and execute a new boot ot the operating
system (CP/M 2.2, 3.0 or TurboDOS). Reutrn to where you were
when the problem occured, while caretully checking each step to
make sure you have not introauced an error. Chances are, you
will discover that there really isn't a system problem. However,
there may be a situation where there really has been a tailure in
the system; in which case you will have to isolate the problem so
that the.SUPER STAR can be put back into an operating condition
as soon as possible.
8.3 AidS To Troubleshooting
To aid in isolating a problem with the SUPER STAR, several
sources ot intormation are provided in this manual.
1. This section ot the manual which presents certain
procedures that can help in isolating a problem with
hardware.
2. Appendix E which provides intorrnation on internal
cables, pin assignments tor connectors, as well as
intormation on the power Supply.
