╘HE FOLLOWING IS A LIST OF BUGS IN THE ├64 OPERATING SYSTEM. ╔T IS KINDLY PROVIDED BY ═IKE ═EYER (WHO DOESN'T EVEN OWN A 64) AND WHO GOT IT FROM ┴. ╥AY ═ILLER OF THE ╒NIVERSITY OF ╔LLINOIS, WHO PUT IT ON ┴╥╨┴╬┼╘. ╫E HAVE TRIED ALL THESE SITUATIONS, AND THEY ARE ALL REAL. ╘HE TEXT IS AS TRANSMITTED, ONLY EDITED FOR SPELLING:
1) ╔╬╨╒╘ ┴ READS A NUMBER FROM THE KEYBOARD. ╔F SOMETHING BESIDES A NUMBER IS TYPED, LIKE A LETTER, AN ERROR MESSAGE IS PRINTED. ┬╒╘ IF YOU TYPE THE LETTER ┼, THE ├64 TAKES IT AS VALID INPUT (AND ASSIGNS ┴ THE VALUE 0).
2) ╩OYSTICK PORT 1, FIRE BUTTON NOT PRESSED, IN THE WEST DIRECTION, MAPS TO THE ├╘╥╠ KEY. ╘HIS, OF COURSE, SLOWS THE MACHINE DOWN TO A CRAWL- EVEN IN MACHINE LANGUAGE.
3) ╘HE "SCRATCH AND REPLACE" COMMAND COMMAND ON THE 1541 DISK DRIVE *SOMETIMES* CAUSES THE FILE POINTER IN THE DIRECTORY TO GET MESSED UP. ╘HUS, TWO FILE ENTRIES IN THE DIRECTORY CAN POINT TO THE SAME PLACE. ╘HIS, NATURALLY, CAUSES YOU TO CPMPLETELY LOSE THE TEXT OF ONE OF THE FILES. ╘HEREFORE, ╬┼╓┼╥ USE THIS COMMAND. ╔NSTEAD, ╙├╥┴╘├╚ AND THEN ╙┴╓┼ SEPARATELY.
4) ╘HE "WEDGE" PROVIDED WITH THE THE 1541 DRIVE CAN HAVE SOME UNDESIRED SIDE EFFECTS.
-╨╥╔╬╘# TO TAPE WON'T WORK RIGHT
-┬┴╙╔├ PROGRAMS THAT STORE DATA AND/OR MACHINE LANGUAGE PROGRAMS IN ╥┴═ MAY BOMB (IF IT IS STORED ON TOP OF THE WEDGE, WHICH USES PART OF THE CASSETTE BUFFER AND PART OF THE 4╦ ╥┴═ ABOVE THE ┬┴╙╔├ ╥╧═).
-─ON'T USE THE ╥╙-232 CHANNEL WITH THE WEDGE ACTIVE. ┴T LEAST, NOT WITH A ┬┴╙╔├ PROGRAM. ╔ DON'T KNOW IF IT ALSO CROAKS MACHINE LANGUAGE, BUT IT CAN CONFUSE ┬┴╙╔├.
5) ╘HE BEST IS SAVED FOR LAST! ╔F YOU TYPE OR PRINT MORE THAN 80 CHARACTERS ON THE ┬╧╘╘╧═ OF THE SCREEN, AND THEN TRY TO DELETE BACK PAST THE 80TH COLUMN, THE MACHINE WILL HANG. ┬E CAREFUL, THIS MUST OCCUR ON THE BOTTOM. ╔F THE TOP LINE IS FULL WHEN YOU PASS COLUMN 40, IT WILL DOUBLE SCROLL AND NOT CRASH. ╔T MUST BE ON THE BOTTOM. ╠ET ME GIVE AN EXAMPLE:
╘YPE ╙╚╔╞╘-├╠╥Çú╚╧═┼ (TO CLEAR THE SCREEN TO PREVENT DOUBLE SCROLLING).
╨OSITION THE CURSOR IN THE LOWER LEFT CORNER OF THE SCREEN.
╘YPE IN 85 LETTERS (╬╧ CARRIAGE RETURNS- THIS MUST BE ONE CONTINUOUS LINE).
╘YPE SEVERAL ╔╬╙╘/─┼╠ KEYS UNTIL YOU PASS BACK ACROSS THE 80TH CHARACTER.
┴T THIS POINT YOUR MACHINE WILL DIE AN AGONIZING, BUT SURE DEATH.
╘HIS WORKS IN EDITOR MODE, UNDER ┬┴╙╔├ PROGRAM MODE (USING ╔╬╨╒╘, ╟┼╘, OR EVEN ╨╥╔╬╘╔╬╟ING IT), AND MACHINE LANGUAGE. ╘HIS, OF COURSE, IS BECAUSE THE BUG IS LOCATED IN THE KERNAL AND ALL ╔/╧ HAS TO GO THROUGH THOSE ROUTINES. ╘HESE KERNAL ROUTINES ARE NOT SIMPLE ╔/╧ ROUTINES, BUT THEY SET ALL SORTS OF SIDE EFFECT FLAGS FOR THE ┬┴╙╔├ SCREEN EDITOR. ╧BVIOUSLY, SOMETHING IS NOT GETTING RESET PROPERLY.
