inconvenience caused by an inadvertent user error, power failure,
or computer failure. Keep a piece of masking tape over the write
protect notch on each diskette as much as possible to protect
against the information being accidentally destroyed. The write-
protect tape should NEVER be removed from your original HORIZON
diskette.
All diskettes should contain a label describing the diskette
contents and relevant version numbers and dates. When not
inserted in the computer, diskettes should be filed in the
protective envelopes in a dust-free location away from excessive
heat and magnetic fields where accidental physical damage can not
occur. Avoid any contact with the diskette media through the
holes in the diskette case.
MAINTENANCE
Periodically use the North Star Monitor program to test all the
RAM memory in the computer, and use the DOS disk test utility to
test each drive.
R~fer
to the Getting Started section of the
North Star System Software Manual for complete details of how to
perform these test procedures.
To keep your computer looking attractive, care for it as you
would a piece of furniture: wipe fingerprints and dirt from the
front panel, and occasionally polish the wood cover.
TROUBLESHOOTING
Should your computer system become non-operational, the first
step is to isolate the problem. If you have determined that the
problem is with the HORIZON computer (and not, for example, with
the terminal, a bad diskette, or with a change in software),
then, if possible, run your boards in another S-100 computer one
at a time to isolate the bad board. If this is not possible,
then follow the checkout procedure in the assembly manuals for
each component of your system.
OUT OF WARRANTY REPAIR
If your unit is out of warranty and you are unsuccessful at
diagnosing or repairing the problem, out-of-warranty service may
be arranged with a local dealer or other experienced local
computer technician .. Alternatively, any North Star products may
be shipped PREPAID to the North Star address with a clear written
description of the problem. Include as many details as possible
about the problem and about your system configuration. Your unit
will be returned, C.O.D., within 30 days after receipt by North
Star. Out-of-warranty repair service is billed at the rate of
$25.00 per hour. If you wish to place an upper limit on the
amount of time spent on your unit, mention this in the written
description.
