╚ERE ARE THE ANSWERS TO ├OMMODORE ╘RIVIA ┼DITION #3 FOR ╞EBRUARY, 1994.


╤ $020)  ╫HAT DOES THE LETTERS ╔┼┼┼ IN ╔┼┼┼-488 STAND FOR?

┴ $020) ╔NSTITUTE OF ┼LECTRICAL AND ┼LECTRONICS ┼NGINEERS.

╤ $021) ╫HAT WAS THE LOGO OF ┬ATTERIES ╔NCLUDED?

┴ $021) ╔T WAS A THE FACE AND HANDS OF A MAN WITH GLASSES INSIDE A CIRCLE.
        ┼ARLY RENDITIONS OF HIM WERE IN BLACK AND WHITE, WHILE LATER ONES HAD
        HIM WITH BLOND HAIR A A RED SHIRT.  ╙OME VIEWS HAD HIM ACTUALLY
        TYPING ON THE 64/╓╔├ WITH ONE FINGER, BUT MOST JUST SHOWED HIM,
        NOT THE KEYBOARD.

╤ $022) ╘HE ├OMMODORE ╓╔├-20, 64, AND 128 COMPUTERS EMULATE IN SOFTWARE A VERY
        IMPORTANT INTEGRATED CIRCUIT. ╫HAT IS ITS NUMBER, AND WHY IS IT
        IMPORTANT?

┴ $022) ╘HE 6551 ╒┴╥╘ ╔├.  ╔T IS USED FOR ╥╙-232 COMMUNICATIONS.

╤ $023)  ├OMMODORE WATCHES PLAY A BEAUTIFUL SONG FOR THE ALARM.  ╫HAT IS THE
         SONG'S TITLE?

┴ $023) ╞LEUR-DE-LIS.  ╘HE "╟ODFATHER" THEME.

╤ $024) ╘HE ├2╬ STYLE ├OMMODORE TAPE DECKS ARE IMPRESSIVE IN HANDLING ERRORS.
        ╚OW MANY TIMES IS A SINGLE PROGRAM STORED ONTO TAPE?

┴ $024) ╘WICE, SECOND COPY IS PLACED RIGHT AFTER THE FIRST.  ╘HAT MEANS, EVEN
        IF YOU GET A LOAD ERROR ON LOAD, YOU MIGHT BE ABLE TO JUST RUN THE
        PROGRAM ANYWAY, AS A LOAD PUTS THE FIRST COPY IN MEMORY, AND VERIFIES
        IT AGAINST THE SECOND COPY.

╤ $025)  ╫HAT IS A JIFFY?

┴ $025) ┴ JIFFY IS 1/60TH OF A SECOND.  ╔T IS THE SAME ON ╨┴╠ AND ╬╘╙├
        ├OMMODORE COMPUTERS.

╤ $026) ╫HAT IS THE SCREEN RESOLUTION OF THE ├OMMODORE ╓╔├-20?

┴ $026) ╧N THE ╓╔├-╔ ╔├, THE TEXT AND GRAPHICS SCREENS ARE DEFINABLE WITHIN
        LIMITS.  ╘HEREFORE, THERE ARE A NUMBER OF ANSWERS THAT ARE CORRECT:
        ╘HE DEFAULT SCREEN HAS (AND THE ANSWERS ╔ WAS LOOKING FOR):
        ╘EXT:     22╚ X 23╓ = 506 CHARACTERS
        ╟RAPHICS: 176╚ X 184╓ = 32384 PIXELS


        ╚OWEVER, ON EXPERIMENTATION WITH A ╬╘╙├ ╓╔├-╔ (6560), ╔ FOUND THAT
        IT COULD SUPPORT A RESOLUTION OF:
        ╘EXT:     24╚ X 29╓ = 696 CHARACTERS
        ╟RAPHICS: 192╚ X 232╓ = 44544 PIXELS
        ┘OUR MILEAGE MAY VARY, BUT THESE NUMBERS REMOVE ALL BORDER AREA.
        (╔ AM NOT SURE IF YOU CAN USE ALL THE PIXELS, SINCE THE ╓╔├-╔ ONLY
        ALLOWS 32768 TO BE USED.  ┘OU MIGHT BE ABLE TO FLIP THE GRAPHICS
        PAGE IN THE MIDDLE OF THE SCREEN, BUT ╔ LEAVE THAT AS AN EXERCISE.)


        ╘HE ╓╔├-╔ ALSO SUPPORTS A VIRTUAL SCREEN, WHICH CAN BE "PANNED" SO
        THAT THE PHYSICAL SCREEN BECOMES A "WINDOW" INTO THE VIRTUAL SCREEN.
        ╘HE MAXIMUM "SCROLLABLE" VIRTUAL SCREEN ON ╬╘╙├ IS:
        ╘EXT:     28╚ X 32╓? = 896 CHARACTERS
        ╟RAPHICS: 224╚ X 256╓? = 57344 PIXELS
        ╘HE ╓╔├ SUPPORTS MORE RESOLUTION THAN 32╓, BUT YOU CAN NEVER SEE
        IT SINCE YOU CAN'T SCROLL IT INTO VIEW, SO THE POINT IS MOOT.
        ╙O, IF ╔ DIDN'T THOROUGHLY CONFUSE YOU, EMAIL ME AND ╔ WILL MAKE
        SURE ╔ DO!


╤ $027) ╫HY IS THE ╓╔├-20 NAMED THE ╓├-20 IN ╟ERMANY?

┴ $027) ┬ECAUSE '╓" IS PRONOUNCED '╞" IN ╟ERMANY, AND THE RESULTING
        PRONUNCIATION WAS A NAUGHTY WORD.

        ├OMMODORE PUT ONE OVER ON MANY PEOPLE.  ╘HE ╓╔├-20 WAS DESIGNED IN
        THE STATES AND GIVEN THAT NAME DUE TO THE ╔├ THAT DID THE GRAPHICS.
        ╫HEN THE MARKETING STARTED, ├┬═ FOUND OUT THE NAME WAS NO GOOD IN
        ╟ERMANY, SO THEY QUICKLY RENAMED IT ╓├-20.  ╘HE AFTER-THE-FACT
        ╓OLKS-├OMPUTER CONJURED UP IMAGES OF THE ╓OLKSWAGON CAR (╓╫), WHICH
        WAS POPULAR AT THE TIME FOR ITS DEPENDABILITY AND PRICE.  ╘HE REST IS
        HISTORY...



╤ $028)  ╫HY WAS EARLY ├OMMODORE EQUIPMENT BUILT INTO SUCH HEAVY ENCLOSURES?

┴ $028) ╙IMPLE.  ├OMMODORE MADE OFFICE FURNITURE, WHICH INCLUDES DESKS AND
        FILING CABINETS.  ╘HEY SIMPLY USED THE FACILITIES AND PARTS ON HAND.
        ╘HE FACT THAT, AT THE TIME THE ╨┼╘ CAME OUT, PEOPLE EQUATED PHYSICAL
        STABILITY OF A MACHINE AS AN INDICATION OF ITS WORTH, SERVED ONLY TO
        REINFORCE THE DECISION.  ┴LSO, THE SYSTEM HAD TO HOLD UP THE BUILT-IN
        MONITOR.

        ═OST PEOPLE THINK IT IS DUE TO ╞├├ REGULATIONS.  ╞├├ REGULATIONS HAD
        NOT BEEN DETERMINED AT THE TIME THE ╨┼╘ CAME OUT, ALTHOUGH THE
        ENGINEERS DID KNOW THAT THE ├╥╘ PRODUCED MANY ELECTRICAL HAZARDS WHICH
        COULD BE ALLEVIATED WITH A SHIELDED METAL CASE.  ├OMMODORE HAS ALWAYS
        BEEN A "CHEAP" COMPANY, SO THE FACT THAT THEY COULD GET GOOD
        SHIELDING IN-HOUSE AT ALMOST NO COST PROEVD TO BE THE OVERRIDING
        FACTOR. ╔T MIGHT INTEREST SOME TO NOTE THAT, EVEN WITH THE METAL
        CASE, EARLY ╨┼╘S HAD FOIL INSIDE AS A SECONDARY SHIELD.  ╘HE REASON
        HAS TO DO WITH THE KEYBOARD BEING MOSTLY PLASTIC, AS THE SHIELD FIT
        DIRECTLY UNDERNEATH, BUT THE REASON FOR IT REMAINS A MYSTERY TO ME.



╤ $029) ╫HAT TWO ┬┴╙╔├ 2.0 COMMANDS MIGHT STILL WORK IF MISPELLED?



┴ $029) ╘HE ANSWERS ╔ WAS LOOKING FOR ARE ┼╬─ AND ╙╘╧╨, ALTHOUGH SOMEONE
        CORRECTLY POINTED OUT THAT ╟╧ ╘╧ CAN BE CONSTRUED AS A MISPELLING.
        ┴LSO, PRINT#, GET#, AND INPUT# MIGHT WORK IF THE '#' WAS OMITTED AND
        THE PROGRAM WAS GETTING DATA TO SCREEN OR KEYBOARD.
        ┴LTHOUGH THE FOLLOWING AREN'T REALLY THE RESULT OF MISPELLED COMMANDS,
        ╔ PUT THEM IN, SINCE YOU COULD STRETCH THE DEFINITION OF MISPELLED TO
        INCLUDE THEM.
        ╠┼╘ WOULD WORK IF IT WAS LEFT OUT, SINCE ╠┼╘ WAS AN OPTIONAL
        KEYWORD.  ├OMMANDS OF THE FORM <KEYWORD> <NUMBER OR VARIABLE> WOULD
        WORK IF LETTERS WERE TACKED ONTO THE END. (EXAMPLE: ╥╒╬─┘., PRG HAS
        A VALID LINE 0, AND ─┘ = 0).  ╞INALLY, ╠╧┴─"JIM",8,1GARBAGE WOULD
        WORK DUE TO THE WAY ╠╧┴─ ABSOLUTE WORKED, BUT THAT IS A STRETCH!


╤ $02┴) ╫HAT DOES ├╔┴ STAND FOR? (NOT THE ╒.╙. ├╔┴!)

┴ $02┴) ├╔┴ = ├OMPLEX ╔NTERFACE ┴DAPTER.  ╘HE GERMAN ═AGAZINE 64'ER CALLS
        IT A ├ONTROL ╔NTERFACE ┴DAPTER, BUT THAT IS NOT ITS OFFICIAL
        NAME.

╤ $02┬) (HARD ONE) ╫HAT IS THE KEY ╓╔├ CAPABILITY THAT MAKES FULL-SCREEN
        HIRES GRAPHICS POSSIBLE ON THE _╓╔├-20_?

┴ $02┬) ┴ LOT OF PEOPLE ANSWERED REDEFINABLE CHARACTERS, BUT THAT ALONE DOES
        NOT PROVIDE ╞╒╠╠-╙├╥┼┼╬ GRAPHICS. 256 8*8 CELLS GIVES YOU A LITTLE
        OVER 1/2 OF THE SCREEN IN GRAPHICS, BUT THE ╓╔├ HAS THE ABILITY TO
        MAKE EACH CHARACTER CELL BE 8*16, WHICH GIVES ENOUGH PIXELS TO MAP
        THE ENTIRE DEFAULT SCREEN.

╤ $02├) ╚OW MANY CASSETTE PORTS DOES THE ├┬═ 8032 COMPUTER HAVE?

┴ $02├) ╘WO.  ╧NE ON BACK, ONE ON SIDE NEAR THE BACK.


╤ $02─) ╫HAT 5 BYTES MUST APPEAR IN EVERY ├OMMODORE 64 AUTOSTART CARTRDGE AND
   WHAT LOCATION IN MEMORY MUST THEY BE PLACED AT?

┴ $02─) ├┬═80 AT $8004.  ╘HE LETTERS MUST HAVE BIT 7 SET. ╙O, THE ACTUAL
        ╨┼╘╙├╔╔ CODES ARE 195, 194, 205, 056, 048.
                     $C3, $C2, $CD, $30, $30 IN ╚┼╪

╤ $02┼) ╫HAT IS THE CORRECT ├OMMODORE TECHNICAL TERM FOR "╙PRITES"?

┴ $02┼) ═╧┬S, OR ═OVABLE ╧BJECT ┬LOCKS.


╤ $02╞) (╘HREE PARTER, ALL PARTS MUST BE CORRECT)  "╨USH-WRAP-CRASH" IS A
        NICKNAME FOR A CONDITION THAT CAN LOCK UP AN OLD-STYLE ├=64.
        ╫HAT CAUSES IT?
        ╚OW CAN IT BE AVOIDED (BESIDES NOT DOING IT)?
        ╫HAT IS THE ONLY WAY OUT ONCE IT HAS OCCURED (BESIDES REBOOTING)?

┴ $02╞) ╫OW, ╔ GOT SO MANY RESPONSES TO THIS!  ╘HIS QUESTION ACTUALLY
        DEALT WITH A TYPICAL USER, BUT PEOPLE SENT IN DESCRIPTIONS OF
        WHAT THE CODE DOES AND HOW TO PATCH IT. ╙O, THERE ARE TWO SETS
        OF ANSWERS TO THIS:

    ╒SER ┴NSWER:

    1) ╔F YOU PUT THE CURSOR AT THE BOTTOM OF THE SCREEN AND TYPE 82 CHARACTERS
       (NOT 81) AND THEN TRYING TO DELETE BACK TO THE 78TH ONE.

    2) ┴NY OF THE FOLLOWING WILL WORK:
          ─O NOT USE THE FOLLOWING COLORS FOR THE CURSOR: RED, BLUE, YELLOW,
          LIGHT RED, DARK GREY, LIGHT BLUE, LIGHT GRAY.

          ╙OME PEOPLE DEVISED A ╔╥╤ WEDGE THAT WILL RECOVER FROM THE LOCKUP.

          ╚AVE THE FOLLOWING LINES AS THE FIRST LINES OF A PROGRAM:
          10 OPEN 15,8,15 20 INPUT#15,A$.

    3) ╘HERE ARE ACTUALLY TWO WAYS TO RECOVER.  ╘HEY ARE:

          ╔F YOU HAVE A RESET BUTTON INSTALLED ON THE 64, RESET THE MACHINE,
          THEN LOAD AND RUN AN UNNEW PROGRAM.  (╔ ACCEPTED THIS, BUT ╔ FIGURED
          MOST PEOPLE WOULD ASSUME THIS MUCH)


          ╔F YOU HAVE A TAPE DRIVE INSTALLED, PRESS EITHER ╙HIFT-3 OR MOVE A
          JOYSTICK INSTALLED IN ╨ORT 1 IN THE ╒╨ DIRECTION.  ╘HEN, RESPOND TO
          THE DIRECTIONS ON THE SCREEN "╨╥┼╙╙ ╨╠┴┘ ╧╬ ╘┴╨┼". ╬EXT, PRESS
          ╥╒╬-╙╘╧╨ TO STOP THE TAPE LOAD.

    ╫HAT REALLY HAPPENS: (╔ CAN'T PROVE THIS)


    1) ╘HE USER TYPES THE LINE OF TEXT AND THE SCROLL CODE IS INVOKED.
       ╘HE FIRST TWO LINES BECOME LINKED AS ONE LOGICAL LINE, AND THE
       THIRD LINE IS TREATED AS A NEW LINE.

       ╘HE USER DELETES THE 82ND AND THE 81ST CHARACTER AND THEN HITS DELETE
       WHILE IN THE FIRST COLUMN OF THE THIRD LINE.  ╙INCE THE DELETE WILL PUT
       THE CURSOR BACK UP INTO THE SECOND LINE, WHICH IS LINKED WITH THE FIRST,
       THE ╦┼╥╬┴╠ GETS CONFUSED AND THINKS THE SECOND LINE IS AT THE BOTTOM OF
       THE SCREEN. ╥EMEMBER, THE "CURSOR" IS ACTUALLY CONSTRUCTED BY A
       COMBINATIONS OF USING REVERSE CHARACTERS AND CHANGING THE COLOR ╥┴═
       NYBBLE FOR THAT SCREEN LOCATION.  ╘HUS, WHEN THE CURSOR GETS "ERASED"
       FROM THE FIRST COLUMN OF THE LAST LINE, THE ╦┼╥╬┴╠ THINKS THE COLOR
       NYBLE FOR IT IS AT $─├00, WHICH IS 40 BYTES OFF FROM THE ACTUAL
       POSITION.  $─├00 IS ACTUALLY ╨ORT ┴ FOR ├╔┴ #1, WHICH IS WHERE THE
       KERNAL WRITES THE COLUMN OF THE KEYBOARD IT WISHES TO SCAN. ┬ECAUSE THE
       ╦┼╥╬┴L IS MESSED UP, IT PUTS THE COLOR NYBBLE FOR WHERE IT THINKS THE
       CURSOR WAS INTO THIS LOCATION. (╘HAT IS WHY THERE IS A CONNECTION
       BETWEEN CURSOR COLOR AND THIS BUG.

       ╬OW, THE SYSTEM INTEGRITY HAS BEEN COMPROMISED, BUT IT DOES NOT SHOW
       YET.  ╘HE USER PROCEEDS TO DELETE THE 80TH CHARACTER.  ┴S THE USER
       DELETES THE 79TH CHARACTER, THE BAD VALUE IN $─├00 GOES TO WORK AND
       FOOLS THE ╦┼╥╬┴L INTO THINKING ╙╚╔╞╘/╥╒╬-╙╘╧╨ HAS BEEN PRESSED.  ╔T ALSO
       PRETTY MUCH DISABLES THE KEYBOARD.

    2) ╙INCE THE ├OLOR ╥┴═ IS WHAT THE ╦┼╥╬┴L GETS CONFUSED ABOUT, THE SOLUTION
       WAS TO NOT USE CERTAIN BIT PATTERNS OF COLORS:

          ╥┼─         0010
          ├┘┴╬        0011
          ┬╠╒┼        0110
          ┘┼╠╠╧╫      0111
          ╠╔╟╚╘ ╥┼─   1010
          ─┴╥╦ ╟╥┴┘   1011
          ╠╔╟╚╘ ┬╠╒┼  1110
          ╠╔╟╘ ╟╥┴┘   1111

          ╧╦ ├OLORS:

          ┬╠┴├╦       0000
          ╫╚╔╘┼       0001
          ╨╒╥╨╠┼      0100
          ╟╥┼┼╬       0101
          ╧╥┴╬╟┼      1000
          ┬╥╧╫╬       1001
          ═┼─╔╒═ ╟╥┴┘ 1100
          ╠╔╟╚╘ ╟╥┼┼╬ 1101
          ┴LL OF THE ┬┴─ COLORS HAVE BIT 1 SET.  ╔ HAVE NO IDEA WHAT THE
          SIGNIFICANCE OF THAT IS.

    3) ┘OU NEEDED TO GET OUT OF THE TAPE LOAD CODE, BUT YOU ONLY HAD SO MANY
       KEYS THAT WERE STILL ACTIVE.  ╙O, IF YOU FOLLOWED THE DIRECTIONS ON
       THE SCREEN, YOU COULD BREAK OUT.  ╙INCE THE TAPE LOAD CODE USES ├╔┴ #1
       FOR ITS OPERATIONS, IT WOULD TAKE OVER THE ╔├ AND THEN RESTORE IT
       TO A CORRECT STATE WHEN EITHER THE LOAD WAS STOPPED OR THE LOAD
       COMPLETED.  ╬OW, THAT IS AMAZING!
       (╙OMEONE IS FREE TO CHECK UP ON ME CONCERNING THIS, SINCE ╔ DO NOT
        HAVE A ╥EV 1 ╥╧═ TO TRY OUT.  ╔F SOMEONE HAS ONE, ╔ WOULD LIKE TO
        HAVE A COPY OF IT ON DISK OR IN EMAIL.  ┴ND IF SOMEONE HAS THE
        INFORMATION ON THIS BUG FROM EITHER THE ═AY 1984 ╟AZETTE P108, OR
        FROM THE ├╧═╨╒╘┼! ╘OOLKIT ╦ERNAL ╓╔├20/64, ╔ WOULD LIKE A COPY.)

╬EW QUESTIONS COMING!
