Loki ma za\u010diatkom t\u00fd\u017ed\u0148a prepadol ot\u00e1zkou kedy m\u00f4\u017eeme kone\u010dne da\u0165 stretnutie, tak hovor\u00edm, \u017ee najsk\u00f4r ke\u010f sa vycestovanci vr\u00e1tia z j\u00falov\u00fdch v\u00fdjazdov\u00fdch akci\u00ed, ak ho chceme ma\u0165 v plnej sile. Nakoniec som mu ale minul\u00fd utorok 16.7. spravil rados\u0165 a privolil na susedsk\u00fd mini sindikat kde sme sa pozreli na dva z jeho Commodorov – DKP #9 a #10. Obe ma\u0161iny s\u00fa z verzie \u201cbreadbin\u201d v tmavo\u0161ed\u00fdch plastoch – ak som dobre v tom pr\u00edtm\u00ed videl.
<\/p>\n\n\n\n
Prv\u00fd z nich m\u00e1 v starej \u201cbreadbin\u201d doske osaden\u00e9 nov\u00e9 rev\u00edzie \u010dipov VIC (8565) aj SID (8580R5). Ako sa uk\u00e1zalo po meran\u00ed, pod\u013ea v\u0161etk\u00e9ho ten kto \u010dipy prehadzoval sa neun\u00faval upravi\u0165 nap\u00e1jacie vetvy a do oboch \u010dipov na\u010falej \u017ehav\u00ed VDD +12V. Je mal\u00fd z\u00e1zrak, \u017ee sa tie \u0161v\u00e1by e\u0161te neodk\u00farili, lebo tieto rev\u00edzie maj\u00fa by\u0165 nap\u00e1jan\u00e9 +5V (VIC-II) resp. +9V (SID-II). Ma\u0161ina sa ale st\u00e1le tv\u00e1ri \u017eivotaschopne a najhor\u0161ie \u010do sa m\u00f4\u017ee sta\u0165, \u017ee bude treba zhoren\u00e9 obvody nahradi\u0165 star\u0161\u00edmi verziami, alebo sk\u00fasi\u0165 upravi\u0165 nap\u00e1jacie vetvy
<\/p>\n\n\n\n
Druh\u00fd bol tvrd\u0161\u00ed orie\u0161ok. Doska nejavila \u017eiadne zn\u00e1mky \u017eivota. Po zmeran\u00ed sme zistili ch\u00fdbaj\u00face nap\u00e4tia za stabiliz\u00e1tormi 7812 a 7805. Pr\u00ed\u010dinou samozrejme bola vyp\u00e1len\u00e1 poistka na 9VAC vetve. Po jej v\u00fdmene sa za\u010dal stato\u010dne hria\u0165 elektrolyt 1000u\/25V. Ten sme tie\u017e vymenili a pokra\u010dovali \u010falej. Loki spomenul, \u017ee dosku z druhej strany e\u0161te ani nevidel, tak sme si ju spolo\u010dne pozreli. Ve\u013ek\u00e9 prekvapenie \u010dakalo okolo modul\u00e1tora, kde boli piny na jednej strane kompletne zbaven\u00e9 c\u00ednu, pri\u010dom druh\u00e1 strana bola st\u00e1le veselo priletovan\u00e1. Loki trval na tom, \u017ee cel\u00fd modul\u00e1tor, chce vymeni\u0165 za mal\u00fa do\u0161ti\u010dku, ktor\u00fa z\u00edskal od Martyho. Do\u0161ti\u010dka generuje iba jasov\u00fa a farebn\u00fa zlo\u017eku, tak\u017ee je pou\u017eite\u013en\u00e1 iba pre monitory s S-Video vstupom. Vhodn\u00fd k\u00e1bel sme nemali, tak\u017ee sme vo v\u00fdsledku videli iba jasov\u00fa zlo\u017eku, ale u\u017e aj to pote\u0161ilo. Videli sme aspo\u0148 kr\u00e1snu \u010diernu tmu :). Na rad pri\u0161la dianostick\u00e1 ROM v kartrid\u017ei, ktor\u00e1 n\u00e1m zahl\u00e1sila vadn\u00fa RAM \u010dislo (tu\u0161\u00edm) 7 a po jej v\u00fdmene postupne tri \u010fal\u0161ie. V\u0161etky vadn\u00e9 RAM boli od jedn\u00e9ho v\u00fdrobcu, ostatn\u00e9 boli kadejak\u00e9 pomie\u0161an\u00e9. Ke\u010f\u017ee tento kus C=64 u\u017e evidentne pre\u0161iel rukami servis\u00e1ka, boli takmer v\u0161etky IO v p\u00e4ticiach. V\u00fdmena pam\u00e4t\u00ed sa preto zdala by\u0165 hra\u010dkou v trvan\u00ed r\u00e1dovo sek\u00fand. Opak bol pravdou. Nap\u00e1jacie v\u00fdvody pam\u00e4t\u00ed boli zaletovan\u00e9 zvrchu na piny prec\u00edznych p\u00e4t\u00edc. Po pr\u00e1cnom vypreparovan\u00ed prvej RAM bolo jasn\u00e9, \u017ee toto mala by\u0165 poistka proti vyskakovaniu \u010dipov z p\u00e4t\u00edc, lebo mali skr\u00e1ten\u00e9 v\u00fdvody – zrejme boli z nie\u010doho povyberan\u00e9. Na prv\u00fd poh\u013ead trivi\u00e1lna v\u00fdmena pam\u00e4t\u00ed dala zabra\u0165 asi hodinu. \u0160\u0165ast\u00edm bolo, \u017ee p\u00e4tice boli prec\u00edzne a sta\u010dilo tak nahradi\u0165 iba 2 piny z ka\u017edej. Keby boli oby\u010dajn\u00e9, bolo by ich treba vybra\u0165 komplet a hne\u010f by sa nazbieralo 64 v\u00fdvodov na ods\u00e1vanie alebo vyf\u00fakanie.<\/p>\n\n\n\n
Po oper\u00e1cii RAM sme zostavu zapli, ale op\u00e4\u0165 bolo na obrazovke \u010dierno. Jemne som \u0165ukol do VICu a ten sa nejako prebral, na obrazovke sa zjavilo \u0161tandardn\u00e9 hl\u00e1senie Commodore Basicu. Op\u00e4\u0165 sme pripojili diag ROM a zbehli testy. Tentokr\u00e1t sa javilo v\u0161etko funk\u010dn\u00e9, vr\u00e1tane testu SIDu. Ma\u0161inu sta\u010dilo len zakapotova\u0165, no predt\u00fdm sme e\u0161te prepastovali chladi\u010d nad VICom.<\/p>\n\n\n\n
Stretnutie sme zakon\u010dili poh\u013eadom na \u010diasto\u010dn\u00e9 zatmenie mesiaca, ktor\u00e9 bolo na \u010distej oblohe kr\u00e1sne vidite\u013en\u00e9. Po\u010dasie naozaj prialo.<\/p>\n\n\n\n
Lokiho dodatok po stretnut\u00ed: AV k\u00e1bel s tromi cinchami, na ktor\u00fdch je Y, C a zvuk sa na plnohodnotn\u00e9 otestovanie na be\u017enom TV naozaj pou\u017ei\u0165 ned\u00e1. N\u00e1sledn\u00fd test na monitore uk\u00e1zal, \u017ee ch\u00fdba farebn\u00e1 zlo\u017eka. Zrejme to bude chcie\u0165 poriadnu diagnostiku malej \u010diernej do\u0161ti\u010dky, ktor\u00e1 nahradila modul\u00e1tor pr\u00edpadne v\u00fdmenu VICu.<\/p>\n\n\n\n
