Podarilo sa mi z\u00edska\u0165 Commdore 116. Asi najmen\u0161\u00ed Commodore \u010do sa vyr\u00e1bal. Bohu\u017eia\u013e Tento je chor\u00fd. A ja sa pok\u00fasim ho opravi\u0165. K\u00fapil som ho ako nefunk\u010dn\u00fd ale povodn\u00fd majite\u013e mi prezradil \u017ee p\u00e1r kr\u00e1t sa mi ho podarilo zapn\u00fa\u0165 a be\u017eal v\u010detne reakcii BASICu.<\/p>\n

To ma povzbudilo v tom \u017ee z pacientom to nebude a\u017e tak\u00e9 zl\u00e9.Najprv to zapneme a uvid\u00edme \u010do sa deje.\u00a0 A vrhneme sa na rie\u0161enie.<\/p>\n

Po zapnut\u00ed m\u00e1me pokazen\u00fd obraz.T\u00e1to chyba m\u00f4\u017ee by\u0165 skoro v \u010domko\u013evek Od TEDa cez CPU a RAM a\u017e o ROM. Ale po resete tu m\u00e1me cca spr\u00e1vny obraz ale bez Basic hl\u00e1\u0161ky. A m\u00e1m dojem \u017ee ani farby nesedia.<\/p>\n

T\u00e1to chyba je ale podla servisn\u00e9ho katal\u00f3gu prim\u00e1rne chybou BASIC ROM, ale nevylu\u010duje aj komplexn\u00fa chybu. Bohu\u017eia\u013e niekedy sa stalo \u017ee ani reset nepomohol.<\/p>\n

Tak\u017ee som skontroloval riadiace sign\u00e1ly \u010di maj\u00fa spr\u00e1vnu ve\u013ekos\u0165 a \u010di v\u00f4bec s\u00fa. PHI0, AEC,RAS,RAC,MUX vyzerali sp\u0155avne. Dokonca aj CS0,CS1 a ich odvodeniny KERNAL_CS a BASIC_CS. Ale BASIC_CS som o\u010dak\u00e1val volan\u00e9 \u010dastej\u0161ie. Origin\u00e1l postup navrhuje vymenenie BASIC ROM. Preto som sk\u00fasil ako sa to bude spr\u00e1va\u0165 bez BASIC_ROM<\/p>\n

 <\/p>\n

V\u00fdsledok je rovnak\u00fd ale z t\u00fdm \u017ee na pr\u00e1zdnu obrazovku sa nedostanem ani resetom.<\/p>\n

<\/a>Tak\u017ee sa pok\u00fasime nahradi\u0165 BASIC RAM.<\/p>\n

Servisn\u00fd manu\u00e1l pri komplexnej chybe navrhuje vymeni\u0165\/otestova\u0165\u00a0 TED. \u010co ale zatia\u013e nem\u00e1m ako tak sa budeme tv\u00e1ri\u0165 ze TED je v poriadku.<\/p>\n

\u010eal\u0161\u00ed na rade je CPU. Bohu\u017eia\u013e moja C64 m\u00e1 CPU pri sp\u00e1jkovan\u00ed tak nem\u00e1m ako sk\u00fasi\u0165. Ale podla kontroly sign\u00e1lov z\/do CPU nie\u010do po\u010d\u00edta tak ho vyhl\u00e1sime zatia\u013e za\u00a0 nevinn\u00e9ho.<\/p>\n

\u010eal\u0161ie na rade s\u00fa pam\u00e4te. Zo zauj\u00edmavos\u0165 sk\u00fasime ako sa to bude spr\u00e1va\u0165 bez nich. A v\u00fdsledkom je \u010dierna obrazovka. Podobne dopadne aj odobratie Kernal ROM p.s. Ak by ste mi vedeli pomoc\u0165 z overen\u00edm funk\u010dnosti TEDa alebo CPU pros\u00edm ozvite sa.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
