Minul\u00fa sobotu sa n\u00e1m to rozbiehalo pozvo\u013ena, ale nakoniec sme boli v \u0161pi\u010dke \u201ca\u017e\u201d traja.<\/p>\n\n\n\n\n\n\n\n
Zrejme to sp\u00f4sobilo vyp\u00edsanie term\u00ednu v t\u00fd\u017edni konania, ale na uplynul\u00fa sobotu sa po\u010det \u00fa\u010dastn\u00edkov stretnutia v\u00fdrazne zredukoval. Zo \u201cvzdialen\u00fdch\u201d sa dostavil iba Ub880d a\u017e z \u010falekej Bratislavy a na p\u00e1r hod\u00edn n\u00e1s pri\u0161iel pozrie\u0165 aj sused Loki. Za\u010d\u00ednali sme nie\u010do po desiatej a kon\u010dili asi o pol \u0161iestej.<\/p>\n\n\n\n
Prv\u00e1 na pretras pri\u0161la Silliconova doska Issue 6U z toastracku. Po zapnut\u00ed bol obraz roztrasen\u00fd, ak n\u00e1hodou v\u00f4bec nabehol. Zistili sme, \u017ee po stla\u010den\u00ed resetu sa situ\u00e1cia o dos\u0165 zlep\u0161\u00ed. Zmeral som nap\u00e1janie a zistil, \u017ee je v\u00fdrazne podv\u00fd\u017eiven\u00e9 – len okolo 3.3V no pri stla\u010den\u00ed a podr\u017ean\u00ed resetu tesne pod 4V. Podozrenie padlo na stabiliz\u00e1tor a obvody okolo meni\u010da, ktor\u00e9 by to mohli \u0165aha\u0165 dolu. Tie\u017e som sk\u00fasil povybera\u0165 obvody osaden\u00e9 v p\u00e4ticiach. Po \u201cod\u013eah\u010den\u00ed\u201d dosky som zistil \u017ealostn\u00fd stav spojov pod p\u00e4ticou ULY. Zrejme ju niekto menil a v\u00f4bec to nespravil citlivo. Prv\u00e9 meranie spojov pod\u013ea sch\u00e9my v\u0161ak neprinieslo \u017eiadne vidite\u013en\u00e9 nedostatky. Nap\u00e4tia boli omnoho zdrav\u0161ie a bl\u00ed\u017eili sa k nomin\u00e1lnym hodnot\u00e1m. Tak\u017ee som postupne prid\u00e1val obvody nazad do dosky a ako posledn\u00e9 v porad\u00ed pri\u0161li na rad AY a ULA. Ka\u017ed\u00fd z nich \u0165ahal nap\u00e4tie za stabiliz\u00e1torom zhruba o 1V nadol. K doske bol pribalen\u00fd aj druh\u00fd \u010dip – vraj tie\u017e ULA pre 128. Po\u010det v\u00fdvodov by sedel, ale \u010dip po osaden\u00ed do p\u00e4tice nejavil \u017eiadnu aktivitu, tak\u017ee som sa vr\u00e1til op\u00e4\u0165 k tomu, ktor\u00fd aspo\u0148 \u010diasto\u010dne i\u0161iel, teda v\u017edy najstabilnej\u0161ie vtedy, ke\u010f som vybral CPU z p\u00e4tice alebo ho dr\u017eal v resete.
<\/p>\n\n\n\n
Bl\u00ed\u017eil sa \u010das obeda, na ktor\u00fd sme sa presunuli do domu, lebo na terase by n\u00e1m jedlo asi rozf\u00fakalo. Po pe\u010denom kuriatku s ry\u017eou sme e\u0161te vytla\u010dili sch\u00e9my k dvom verzi\u00e1m toastracku – p\u00f4vodn\u00e9mu Issue 6U aj k verzii Investronica a presunuli sa nazad do dielne.
<\/p>\n\n\n\n
O mal\u00fa chv\u00ed\u013eu sa zjavil Loki a pod pazuchou dr\u017eal zn\u00e1mu bielu krabi\u010dku tvrd\u00e9ho plastu. Samozrejme to nebolo ni\u010d in\u00e9 ako p\u00f4vodn\u00fd obal Didaktiku Gama a dokonca aj s p\u00f4vodn\u00fdm obsahom. Tak\u017ee sme Issue 6U dali prest\u00e1vku a vrhli sa na nov\u00e9ho \u201cpacienta\u201d. Bolo treba trochu zabojova\u0165 pri vyberan\u00ed zdroja z onoho p\u00f4vodn\u00e9ho plastov\u00e9ho obalu, ale ke\u010f sa n\u00e1m to podarilo odhodlali sme sa to rovno zapn\u00fa\u0165. Na obrazovke sa objavili farebn\u00e9 obrazce a vyzeralo to, \u017ee CPU sa nechce rozbehn\u00fa\u0165, ale Loki trochu pokr\u00fatil krabicou a zrazu sa objavil \u201d\u00a9 1989 Didaktik Skalica\u201d. Po rozobrat\u00ed sa ni\u010d na prv\u00fd poh\u013ead nejavilo nezdravo a\u017e na podozriv\u00fd v\u00fdkonov\u00fd odpor pridan\u00fd niekde do obvodu vstupu alebo v\u00fdstupu na magnetof\u00f3n. Nakoniec sme objavili odtrhnut\u00fa no\u017ei\u010dku keramick\u00e9ho kondenz\u00e1tora 100pF v obvode \u010dasovania CAS-RAS 4164. Po jeho v\u00fdmene sme sk\u00fasili nie\u010do nahra\u0165 z divIDE, ale zostava sa javila nestabilne u\u017e pri inicializ\u00e1cii pam\u00e4\u0165ovej karty a hlavne po pridan\u00ed rozdvojky zbernice, na ktorej s\u00fa\u010dasne viselo aj SimpleAY. Chceli sme toti\u017e vysk\u00fa\u0161a\u0165 nejak\u00e9 48k demo.<\/p>\n\n\n\n
Loki na\u010drtol my\u0161lienku, \u017ee by r\u00e1d vymenil t\u00fato Gamu za nejak\u00e9 eMko, lebo pr\u00e1ve to mu e\u0161te v zbierke ch\u00fdba. G\u00e1m by u\u017e mal tri vr\u00e1tane tejto. Tak sme sa pustili do preberania z\u00e1sob mojich eMiek. Samozrejme som ich testoval pred nieko\u013ek\u00fdmi rokmi a zospodu pridal n\u00e1lepky, ktor\u00e9 maj\u00fa ak\u00e9 spr\u00e1vanie v kombin\u00e1cii s divIdE a AY. Vybral som teda ten kus, ktor\u00fd mal fungova\u0165, ale nane\u0161\u0165astie realita bola in\u00e1. Postupne sme prevetrali v\u0161etky kusy. Niektor\u00e9 v\u00f4bec nena\u0161tartovali, in\u00e9 mali probl\u00e9m s kl\u00e1vesnicou – kl\u00e1vesy bu\u010f ne\u0161li v\u00f4bec alebo sa po stla\u010den\u00ed zasek\u00e1vali – a zvy\u0161ok bu\u010f nefungoval s divIDE alebo AY pr\u00edpadne s kombin\u00e1ciou oboch.<\/p>\n\n\n\n
Murphy zafungoval a na konci testovan\u00e9ho radu sa n\u00e1m predsa len podarilo identifikova\u0165 jeden kus, ktor\u00fd okrem nepremazan\u00fdch a sem-tam sa zasek\u00e1vaj\u00facich kl\u00e1ves, vykazoval stabilitu pri plne \u201cnalo\u017eenej\u201d konfigur\u00e1cii. Bolo si na \u0148om tak mo\u017en\u00e9 pozrie\u0165 nov\u0161ie 48k dem\u00e1 v\u00e4\u010d\u0161inou z produkcie Hooy Prg ako napr\u00edklad Critical Error, Dizzzruptor, 48k.

Popri prep\u00ednan\u00ed eMiek UB predviedol Lokimu, ako vyzer\u00e1 oran\u017eov\u00e1 farba na Spektre – UDG dither 55h\/AAh pri \u010derveno-\u017eltom zobrazen\u00ed. Tie\u017e sme testovali na \u0161irokouhlom LCD, ak\u00fd je spr\u00e1vny rozmer obrazu, aby z kru\u017enice nevznikol Dizzy v\u010faka ruskej ULE.
<\/p>\n\n\n\n
Lokimu som vyhrabal zo \u0161ufl\u00edkov d\u00e1ke ch\u00fdbaj\u00face komponenty na cartridge do \u010eal\u0161ie testovanie minikombajnu – rozvdojka s vypadnut\u00fdm k\u013e\u00fa\u010dom, za ktorou bolo divIDE s SD redukciou a SimpleAY – v kombin\u00e1cii s Gamou u\u017e bola cesta ku katastrofe. Pod\u013ea v\u0161etk\u00e9ho tento pokus zobral do krem\u00edkov\u00e9ho neba moju posledn\u00fa redukciu SD->IDE 40 pin, dajak\u00e9 komponenty z divIDE (na\u0161\u0165astie nie GALy a flash – tie som prehodil do inej dosky a otestoval) a asi aj dekod\u00e9r 74*138 na SimpleAY. Pr\u00e1ve posledn\u00fd menovan\u00fd som vymenil e\u0161te po\u010das stretnutia a n\u00e1sledne otestoval na Spektre. Tu sa SimpleAY rozbehlo, ale v Game u\u017e nie. Potom som doplnil ch\u00fdbaj\u00faci k\u013e\u00fa\u010d zbernice, ale tentoraz u\u017e v podobe klinca a nie lepen\u00e9ho kusu odleptan\u00e9ho kuprextitu. UB si pomaly za\u010dal h\u013eada\u0165 spiato\u010dn\u00fd autobus a mne u\u017e bolo jasn\u00e9, \u017ee toho viac nestihneme.<\/p>\n\n\n\n Na kus cesty som ho odprevadil a odobral sa dokosi\u0165 tr\u00e1vu na z\u00e1hradku, hoci som t\u00fato atrakciu mal na pl\u00e1ne a\u017e o de\u0148 nesk\u00f4r. Hoci komorn\u00e9 a s trochou smoly v p\u00e4t\u00e1ch, napriek tomu pr\u00edjemn\u00e9 a tvoriv\u00e9 stretnutie sme ukon\u010dili pred pol \u0161iestou.
