"├ARE AND ╞EEDING OF ├OMPUTERS"
-----------------------------------------------------------------------------
╤─╠ ╠AURA: ╫ELCOME TO THE ╟ENERAL/┬EGINNER'S ├ONFERENCE! ╘ONIGHT'S TOPIC IS
"├ARE AND ╞EEDING OF ┘OUR ├OMMODORE". ╘HE ├OMMODORE ACTUALLY
REQUIRES LITTLE CARE AND WILL PROBABLY TAKE ANY PUNISHMENT YOU
DISH OUT SHORT OF A DIRECT HAMMER STROKE. ┬UT IF YOU HAVE A
GENEROUS HEART AND WANT TO DO MORE, YOU CAN KEEP IT HAPPY AND
HEALTHY AND LOOKING LIKE NEW FOR A LONG TIME!
╟IVING A COMPUTER SPECIALIZED CARE WILL PROLONG ITS LIFE, BUT
THE KEYWORD HERE IS "PREVENTIVE MAINTENANCE". ╘HE MINIMUM YOU
CAN DO IS ABSOLUTELY NOTHING. ╞ACTORY RECOMMENDATIONS ARE
MINIMAL BECAUSE THERE IS LITTLE MECHANICAL CARE YOU CAN PROVIDE
FOR THE MICROELECTRONICS. ╥ATHER THAN SLOWLY GRINDING DOWN,
SOLID-STATE ELECTRONICS TEND TO FAIL IN ONE SWOOP. ╧NE MOMENT
THEY WORK, THE NEXT MOMENT NOTHING IS LEFT BUT YOUR FRUSTRATION.
┘OU SHOULDN'T EXPECT A DISASTER, THOUGH, MORE OFTEN THAN ONCE IN
TENS OF THOUSANDS OF HOURS OF OPERATION. ╘HE FIRST PREVENTIVE
THING TO DO IS TRY TO KEEP YOUR 64 FROM FAILING AFTER THE
WARRANTY. ╥ATHER THAN TENDING TOWARD MINIMAL USE TO KEEP IT
ALIVE, INSTEAD PUSH YOUR ├OMMODORE TO ITS LIMITS. ╘HE LOGICAL
THING TO DO WHEN YOU FIRST BECOME A COMPUTER OWNER IS TO HOOK
IT ALL UP, TURN IT ON, AND ╠┼┴╓┼ ╔╘ ╧╬. ╘HIS IS CALLED THE
"BURN IN" TIME. ╔F SOMETHING IS GOING TO DRASTICALLY FAIL,
CHANCES ARE IT WILL FAIL DURING BURN IN. ╧NCE IT'S PROVED ITSELF,
YOU CAN TAKE ADDED PRECAUTIONS.
╘HE KEYBOARD'S BIGGEST ENEMIES ARE AIRBORNE. ─UST AND EXTREME
HUMIDITY ARE TERRIBLE THINGS FOR YOUR COMPUTER. ┬UT THE KEYS
CAN ALSO BE TAINTED AND TRAPPED BY MORE WORLDLY THINGS, SUCH AS
PEANUT BUTTER AND RUNAWAY COFFEE. ├LIMATE IS IMPORTANT. ╔F IT'S
TOO HOT OR TOO COLD OR TOO DRY OR TOO WET, THE MACHINE CAN
SUFFER. ╘HE BEST ADVICE IS TO USE REASONABLE JUDGEMENT. ─ON'T
PUT THE COMPUTER IN A FILLED BATH TUB. ╘HAT SOUNDS FUNNY, BUT
THINK - YOU MAY BE CONSIDERING PUTTING YOUR COMPUTER IN A DANK
BASEMENT. ╧R EVEN IF THE ROOM YOU'RE IN DOESN'T SEEM HOT TO YOU,
REMEMBER THAT THE CIRCUITS GENERATE HEAT, TOO. ┴ND THE
TEMPERATURES CAN ADD UP.
╘HE TABLE ON WHICH YOU PLACE THE COMPUTER IS IMPORTANT. ┘OU WANT
AIR FLOW UNDER AND AROUND THE COMPUTER KEYBOARD. ╙O DON'T PLACE
IT ON A HEAVILY CUSHIONED SURFACE. ╔N FACT, AT ONE TIME ╔
PLACED FOUR COKE CAPS UNDER MY COMPUTER TO MAKE CERTAIN IT WAS
GETTING PROPER AIR FLOW, DURING A HOT SUMMER AFTER THE AIR
CONDITIONER HAD BLOWN UP.
┴LTHOUGH NONE OF US DO THIS, TRY TO KEEP LIQUIDS AWAY FROM THE
COMPUTER. ╘HE KEYBOARD IS RELATIVELY UNSOPHISTICATED AND HAS
CONTACTS THAT CAN EASILY BE GUMMED UP BY SUGAR POLLUTION. ╔ CAN
ATTEST TO THIS AFTER TRIPPING OVER THE DOG AND SPILLING SUGAR-
LADEN COFFEE INTO THE KEYS. ╔T TOOK DAYS TO CORRECT THAT ONE.
╤UESTION: ═ANY PLACES BAN CIGARETTES AROUND COMPUTERS. ╫HAT IS THE TRUTH
ABOUT THIS HAZARD?
╤─╠ ╠AURA: ╘O BE HONEST, ╔ DON'T SEE MUCH IN IT. ╨ERSONALLY, ╔'VE NEVER HAD
COMPUTERS OR DISKS FAIL DUE TO CIGARETTE SMOKE.
├OMMENT: ╘HOSE PLACES SAVE THEIR EQUIPMENT BUT LOSE SOME GOOD
PROGRAMMERS.
╤─╠ ╠AURA: ╔ TOOK A POLL LONG AGO, AND FOUND THAT 86% OF COMPUTERISTS
SMOKE. ┴T THE STORE ╔ MANAGED, WE KEPT ASHTRAYS OUT AT ALL
TIMES. ╫E ALSO WORE JEANS, SINCE MOST COMPUTER PEOPLE ARE
INTIMIDATED BY SUITS (BROAD GENERALIZATION).
╘HE ├OMMODORE KEYBOARD ITSELF IS MORE DELICATE THAN ITS INTERNAL
CIRCUITRY. ╔T IS HELD TOGETHER BY A "PHENOLIC" CIRCUIT BOARD,
WHICH IS EASILY FRACTURED. ╘OO MUCH ANGER OR A HEAVY HAND
MASSAGE CAN BE FATAL. ═Y LEFT HAND TENDS TO HIT HARDER THAN THE
RIGHT, SO THE LEFT ╙╚╔╞╘ KEY IS SUFFERING BADLY.
╤UESTION: ─OES THIS ALSO APPLY TO THE 128'S KEYBOARD?
╤─╠ ╠AURA: ╞ROM WHAT ╔'VE SEEN, ╔'M PRETTY SURE IT IS. ╟LITCHES AND SPIKES
ARE REAL TROUBLE FOR MOST COMPUTERS. ┬OTH TERMS DESCRIBE
ESSENTIALLY THE SAME PHENOMENON: A TEMPORARY PULSE OF
ABNORMALLY HIGH VOLTAGE ON THE POWER LINE. ┬ECAUSE OF THE BRIEF
DURATION OF SPIKES AND GLITCHES, THEY ARE INVISIBLE. ╘HEY MAY
NOT CAUSE YOUR LIGHTS TO DIM, BUT THEY CAN BE ENOUGH TO DAMAGE
THE MICROCIRCUITS IN YOUR COMPUTER. ╙OME STUDIES HAVE SHOWN THAT
THE RESULTS OF GLITCHES CAN BE ACCUMULATIVE. ┼ACH SPIKE CAN
SLIGHTLY DAMAGE THE TINY INTERNAL STRUCTURE OF THE CIRCUITS.
╫HEN ENOUGH DAMAGE IS DONE, THE COMPUTER CAN MYSTERIOUSLY STOP.
╧R PERHAPS IT MAY WORK ERRATICALLY, REFUSING TO EXECUTE SIMPLE
FUNCTIONS OR GIVING STRANGE ANSWERS TO OBVIOUS QUESTIONS.
╘HE BEST WAY TO PROTECT YOUR COMPUTER FROM POWERLINE SPIKES IS
WITH A SURGE SUPPRESSOR. ═ANY BRANDS AND STYLES ARE AVAILABLE.
╨OWER PROBLEMS IN THE OTHER DIRECTION - LOW VOLTAGE - CAN BE
GUARDED AGAINST BY USING A REGULATOR, BUT THESE CAN BE
EXPENSIVE. ╘HE BEST SOLUTION IS TO JUST ╙┴╓┼ YOUR PROGRAMS
OFTEN SO THAT WHEN/IF THIS HAPPENS, YOU DON'T GO THROUGH
HEARTACHE.
╙TATIC IS ANOTHER ENEMY. ─ON'T SHUFFLE ACROSS THE CARPET THEN
AFFECTIONATELY PAT YOUR COMPUTER. ╨REVENTION IS THE BEST
SOLUTION. ╘HE ├OMMODORE DOES A PRETTY GOOD JOB OF WARDING OFF
STATIC SPARKS. ╘OUCHING THE ├OMMODORE'S INSULATING PLASTIC
DOESN'T DRAIN THE STATIC CHARGE FAST ENOUGH TO GENERATE A
DAMAGING ELECTRICAL SPARK. ╚OWEVER, WATCH OUT WHEN TOUCHING THE
PORTS. ╧NE STATIC DISCHARGE CAN BLOW YOUR WHOLE JOYSTICK PORT,
FOR INSTANCE.
├OMMENT: ╫ATCH OUT FOR THE 128─ CASE, ALSO.
╤─╠ ╠AURA: ╟OOD POINT! ╘HE 128─ DRIVE CASE ╔╙ METAL, SO BEWARE OF THIS. ┘OU
MIGHT CONSIDER BUYING A SMALL "STATIC PAD". ╘HEY'RE VERY CHEAP,
AND THEY ATTACH TO THE DESKTOP OR COMPUTER BY VELCRO. ╩UST TOUCH
THE PAD AND THE STATIC IS DISCHARGED. ╧R YOU COULD RAISE THE
HUMIDITY OF YOUR HOME TO 30% OR HIGHER (MUCH HARDER TO DO).
┴S WITH THE COMPUTER, THE WORST ENEMY OF DISKS IS INVISIBLE.
═AGNETIC MEDIA REQUIRE EXTRA THOUGHT AND CARE. ╦EEP DISKS AWAY
FROM YOUR STEREO SPEAKERS, POWER TRANSFORMERS, ELECTRIC MOTORS,
AND DON'T ABSENT-MINDEDLY LIE ONE ON YOUR TELEPHONE. ╘HE BELL IN
THE PHONE WILL WIPE OUT THE DISK IF THE PHONE RINGS. ╟UARD
AGAINST TOUCHING THE DISK SURFACE. ╘INY DROPS OF OIL ON A
FINGERTIP CAN BE ENOUGH TO MESS UP A DISK AND GUM UP THE WORKS
OF A DRIVE. ─ISK DRIVES REQUIRE CERTAIN CARE, TOO. ┴LTHOUGH
VARIOUS SOURCES DISAGREE ON HOW OFTEN TO CLEAN THE DRIVE HEADS,
ONCE EVERY 20-50 HOURS OF USAGE SHOULD BE ENOUGH FOR THE 1541.
╬OTE THAT THE 1571 AND 1581 DRIVES REALLY SHOULDN'T BE CLEANED
WITH THE KITS THAT YOU PURCHASE. ╘HEY DON'T REQUIRE THE SAME
MAINTENANCE AS THE 1541, AND CLEANING SHOULD BE DONE - WHEN IT'S
NEEDED - BY A SERVICE CENTER. ╧NE WORD OF CAUTION - DO ╬╧╘ USE
COTTON SWABS WHEN CLEANING DRIVE HEADS. ╙TRANDS OF FIBER CAN
COME OFF AND CAUSE BAD PROBLEMS.
├OMMENT: ┼XTREME CAUTI
