Po dlhej rannej odmlke sme sa v predobednom \u010dase zi\u0161li vo \u0161tvorici.<\/span><\/p>\n

<\/p>\n

Zr\u00e1na som stihol sprata\u0165 a o\u010disti\u0165 v\u0161etky stoly a\u017e tak \u00fa\u010dinne, \u017ee som potom cel\u00fd de\u0148 h\u013eadal kdejak\u00e9 kusy vybavenia. K\u00fdm sa dostavili \u00fa\u010dastn\u00edci za\u010dal som sa venova\u0165 mechanike: ako upevni\u0165 SCART konektor osaden\u00fd na samostatnom k\u00fasku plo\u0161n\u00e9ho spoja k doske spolu s CGA\/VGA prevodn\u00edkom HD 9800. Za zhruba hodinku som mal skompletovan\u00fa zostavu – dve dosky upevnen\u00e9 na tretej. E\u0161te k tomu nama\u013eova\u0165 nejak\u00fa pekn\u00fa krabi\u010dku v OpenSCADe a \u010fal\u0161\u00ed vydaren\u00fd projekt bude zav\u0155\u0161en\u00fd.\"\"<\/a><\/span><\/p>\n

\u010ci\u017eo pri\u0161iel na\u013eahko bez osembitov\u00e9ho vybavenia, ale zato priniesol zauj\u00edmav\u00e9 veci\u010dky. Jednak priniesol na opravu fotor\u00e1mik zna\u010dky Sony a jednak nabastlen\u00e9 Wemos veci napichan\u00e9 v breadboarde. Fotor\u00e1mik rozobral a za\u010dali sme zis\u0165ova\u0165 pr\u00ed\u010dinu jeho tot\u00e1lnej hluchoty. Zjavne bol probl\u00e9m v nap\u00e1jan\u00ed. Mne sa najprv zdral by\u0165 zaoxidovan\u00fd nap\u00e1jac\u00ed jack na doske r\u00e1mika, ale n\u00e1sledne sa mi zdali slabo napru\u017een\u00e9 kontakty na jacku na konci \u0161n\u00fary. Tieto dva elementy bolo treba \u010do najr\u00fdchlej\u0161ie a naj\u00fa\u010dinnej\u0161ie ob\u00eds\u0165, tak\u017ee pri\u0161li na rad poctiv\u00e9 meden\u00e9 lankov\u00e9 vodi\u010de naletovan\u00e9 rovno do dosky plo\u0161n\u00e9ho spoja paralelne k nap\u00e1jaciemu jacku. N\u00e1sledne sme druh\u00fd koniec dr\u00f4tov pripojili na laborat\u00f3rny zdroj, nastavili spr\u00e1vne nap\u00e4tie – obvykl\u00fdch 5V – a pr\u00fadov\u00fa poistku na minimum a r\u00e1m\u010dek vskutku za\u010dal poblik\u00e1va\u0165. Sta\u010dilo len upravi\u0165 pr\u00fad na spr\u00e1vnu \u00farove\u0148 a na displeji sa zjavil obraz. Ned\u00e1 sa poveda\u0165, \u017ee by r\u00e1mik bol pr\u00edkonovo skromn\u00fd. Aj bez pripojen\u00e9ho displeja cucol nie\u010do cez pol am\u00e9ra. Ne\u010dudo, \u017ee p\u00f4vodn\u00fd adapt\u00e9r bol dimenzovan\u00fd na medzn\u00fd pr\u00fad 2A. Ke\u010f si predstav\u00edm \u010do v\u0161etko dok\u00e1\u017ee obsl\u00fa\u017ei\u0165 napr. tak\u00e9 Raspberry Pi pri podobnom pr\u00edkone nejako sa mi my\u0161lienka prezerania fotiek tak\u00fdmto nena\u017erancom prestala pozd\u00e1va\u0165.
\n<\/span>Nu\u017e po v\u00fdmene adapt\u00e9ra za in\u00fd generick\u00fd ne-Sony model sa aj konektory uk\u00e1zali ako dosta\u010duj\u00face a r\u00e1mik m\u00f4\u017ee na\u010falej sl\u00fa\u017ei\u0165 svojmu p\u00f4vodn\u00e9mu \u00fa\u010delu. Akur\u00e1t ten n\u00e1hradn\u00fd adapt\u00e9r m\u00e1 jednu \u0161pecialitu: \u010dierny v\u00fdstupn\u00fd dvoj\u017eilov\u00fd k\u00e1bel m\u00e1 podlhovastou sivou preru\u0161ovanou \u010diarou po celej d\u013a\u017eke jednej \u017eily ozna\u010den\u00fd kladn\u00fd p\u00f3l. \u010clovek by tipoval opak a ke\u010f\u017ee som len tipoval a nemeral, musel som letova\u0165 v\u00fdstupn\u00fd konektor dvakr\u00e1t, aby bol nakoniec spr\u00e1vne. Pou\u010denie pre m\u0148a: d\u00f4veruj, ale premeraj!<\/span><\/p>\n

Kr\u00e1tko po \u010ci\u017eovom pr\u00edchode sa ozvali Ub a Otis, \u017ee sa e\u0161te zastavili doplni\u0165 z\u00e1soby a u\u017e-u\u017e pokra\u010duj\u00fa v jazde smerom do dielne, len \u010di sme si e\u0161te n\u00e1hodou nie\u010do nezmysleli. Vymenovali, \u017ee sladkosti, slanosti a pitn\u00fd re\u017eim u\u017e zabezpe\u010dili tak sme ich s \u010ci\u017eom viac nezdr\u017eovali. Do pol hodinky dorazili a t\u00fdm sa po\u010det \u00fa\u010dastn\u00edkov stretnutia dostal na svoje maximum.<\/span><\/p>\n

Otis rozbalil zostavi\u010dku – Harlequina 128k s displejom a divIDE. K tomu pridal pomocn\u00e9 po\u010d\u00edtadlo s logom nakusnut\u00e9o jablka (ach t\u00ed zelovoc\u00e1ri). Ub rozbalil laptop a na \u00favod po\u0161tudoval maily a zreferoval o Leo\u0161ov\u00fdch probl\u00e9moch v IF1Bis, ktor\u00e9 sa preberali na Pandure.<\/span><\/p>\n

So Z00mom sme sa d\u00e1vnej\u0161ie zam\u00fd\u0161\u013eali nad t\u00fdm, \u010d\u00edm by bolo vhodn\u00e9 nahradi\u0165 nedostupn\u00fd 8\u201d LCD TV s ozna\u010den\u00edm PL8006, nesk\u00f4r premenovan\u00fd na L8009 a postaven\u00fd na inom \u010dipsete, ktor\u00fd u\u017e nefunguje poriadne s osembitmi. Stanoven\u00e9 parametre – pomer str\u00e1n 4:3 a bezstratov\u00e9 zobrazovanie \u010di\u017ee minim\u00e1lne 575 PAL riadkov – z\u00fa\u017eili v\u00fdber na 2-3 displeje v prijate\u013enej cenovej rel\u00e1cii pod 30\u20ac. Zak\u00fapil som 2 vzorky a <\/span>jednu z nich<\/span><\/a> sme otestovali po\u010das stretnutia aj ako HDMI zobrazova\u010d ku Raspberry Pi. Uspokojivo vyhovie aj s CGA\/VGA prevodn\u00edkom ku PP01 \u010di Spektru – podrobnosti \u010falej, ale kompozitn\u00fd vstup osaden\u00fd na doske riadiacej elektroniky som zatia\u013e nesk\u00fa\u0161al. E\u0161te to nie je pou\u017eite\u013en\u00e9 ako hotov\u00fd v\u00fdrobok. Bude to chcie\u0165 nakresli\u0165 krabi\u010dku, vytla\u010di\u0165 a zakrytova\u0165, ale povedzme, \u017ee prvotn\u00fdmi testami sme ho nechali prejs\u0165.<\/span><\/p>\n

N\u00e1sledne som nejak\u00fd \u010das som str\u00e1vil testovan\u00edm CGA\/VGA konvertora v kombin\u00e1ci\u00e1ch s r\u00f4znymi ma\u0161inami. Poruke som mal \u010diernu +2A, +3, siv\u00fa +2 a \u010dierny „takmer“ toastrack. Na posledn\u00e9 dva menovan\u00e9 som v\u0161ak nevedel n\u00e1js\u0165 zdroj. Tak dobre som ho toti\u017e pri rannom upratovan\u00ed schoval. +2A a +3 maj\u00fa rovnak\u00fa ULU resp. GA, ale mal som dva SCART k\u00e1ble: jeden <\/span>toastrackov\u00fd<\/span><\/a> (6 odporov, 3 di\u00f3dy) a druh\u00fd <\/span>plustrojkov\u00fd<\/span><\/a> (3 odpory). Pr\u00e1ve ten druh\u00fd vykazoval podozriv\u00e9 spr\u00e1vanie – obraz pod chv\u00ed\u013eou poskakoval a nechcel sa ust\u00e1li\u0165. Probl\u00e9m bol v d\u013a\u017eke k\u00e1bla. Po skr\u00e1ten\u00ed na polovicu u\u017e obraz z oboch po\u010d\u00edta\u010dov vykazoval zhruba rovnak\u00fa stabilitu.<\/span><\/p>\n

Moja snaha presk\u00fama\u0165 v akom stave je Sam Coup\u00e9, ktor\u00e9 mi pred p\u00e1r rokmi daroval Ellvis, stroskotala na prepojovac\u00edch k\u00e1bloch. Ke\u010f som ho d\u00e1vnej\u0161ie testoval vyrobil som si redukciu na nap\u00e1janie z +3 zdroja, ale dakde som ju medzi\u010dasom zapatro\u0161il. Obrazov\u00fd v\u00fdstup som chcel rie\u0161i\u0165 SCARTom, ale spomenul som si, \u017ee posledn\u00fd \u00fapln\u00fd k\u00e1bel tohto typu som rozstrihol na polovicu a vyrobil dva k\u00e1ble pre PP01 a u\u017e spom\u00ednan\u00fd toastrack.<\/span><\/p>\n

\u010eal\u0161ou amb\u00edciou bolo repopulova\u0165 (kr\u00e1sne slovo v\u0161ak – po slovensky zrejme spr\u00e1vne znovu os\u00eddli\u0165) dosku PMD zdroja EA1605, ktor\u00fd sa mi podarilo z\u00edska\u0165. P\u00f4vodn\u00fd majite\u013e toti\u017e za\u010dal zdroj prer\u00e1ba\u0165 na nie\u010do in\u00e9 a vyhodil z dosky v\u0161etky s\u00fa\u010diastky okrem zop\u00e1r vyhladzovac\u00edch kondenz\u00e1torov a usmer\u0148ovac\u00edch di\u00f3d. \u017dia\u013e dod\u00e1vka od Bu\u010deka s krabicou Tesla s\u00fa\u010diastok nestihla dorazi\u0165 v\u010das, preto som moje sna\u017eenie musel odsun\u00fa\u0165.<\/span><\/p>\n

\"\"<\/a><\/p>\n

Hlavne v\u010faka privezen\u00e9mu proviantu sme obed objedn\u00e1vali a\u017e \u010dosi pred jednou a rozvoz z pizz\u00e9rie ho doviezol o nie\u010do sk\u00f4r ako s\u013eubovan\u00fa hodinu. Po \u00faspe\u0161nom skonzumovan\u00ed a polhodinke postgastr\u00e1lnej demencie sme si pozreli \u010ci\u017eove hra\u010dky. Najviac zaujal maticov\u00fd displej s 8×8 LED riaden\u00fd z Raspberry Pi a zobrazuj\u00faci kadejak\u00e9 obrazce.<\/span><\/p>\n

\u010co si spom\u00ednam tak Otis priebe\u017ene rie\u0161il AY hradlo od Fuku. Nebolo mi \u00faplne jasn\u00e9 \u010di nie\u010do upravuje, alebo len sk\u00fama ako to Franta myslel, ale vyzeral pri tom ve\u013emi s\u00fastredene.<\/span><\/p>\n

Na z\u00e1ver sa v dielni uk\u00e1zal aj m\u00f4j najmlad\u0161\u00ed potomok a do\u017eadoval sa nejakej hry na spektrum. Nenapadlo ma ni\u010d lep\u0161ie ako Bomb Jack, ktor\u00fd s vyhegan\u00fdm Sinclair joystickom zrejme nebol \u00faplne vhodnou vo\u013ebou. Dalo n\u00e1m zabra\u0165 sna\u017eenie aplikova\u0165 POKE do hry <\/span>upravenej pre +3<\/span><\/a> a spakovanej Turbo Imploderom. Nakoniec sme zobrali \u00a0<\/span>\u010dist\u00fa TAP verziu<\/span><\/a> od Pavera, ale t\u00e1 pre zmenu na +3 v\u00f4bec ne\u0161la (\u017eeby <\/span>IN #FF probl\u00e9m<\/span><\/a> ?). Nakoniec sme spustili namiesto Bomb Jacka El Stompo a bolo po probl\u00e9me \ud83d\ude42<\/span><\/p>\n

Na\u0161e v\u00fd\u017eivn\u00e9 stretnutie sme uzavreli kr\u00e1tko po siedmej.<\/span><\/p>\n
