V ostatnom \u010dase som zaregistroval, \u017ee zrejme s prib\u00fadaj\u00facim vekom, mno\u017estvom vec\u00ed v dielni alebo len nedostatkom cviku kv\u00f4li nepravidelnosti stretnut\u00ed mi vypratanie a po\u013eud\u0161tenie priestoru, v ktorom sa odohr\u00e1vaj\u00fa, jednoducho trv\u00e1 dlh\u0161ie.<\/p>\n\n\n\n\n\n\n\n

Vypratanie 35 \u00falo\u017en\u00fdch boxov – preva\u017ene prepraviek a ban\u00e1nov\u00fdch krab\u00edc – som za\u010dal dva dni pred stretnut\u00edm. \u010eal\u0161\u00ed de\u0148 som vypratal veci zo stolov a vys\u00e1vanie som ledva stihol pred pl\u00e1novan\u00fdm \u010dasom za\u010diatku. <\/p>\n\n\n\n

To sa u\u017e prv\u00fd virtu\u00e1lny \u00fa\u010dastn\u00edk Pavel (aka pvym) do\u017eadoval zverejnenia URL na on-line pripojenie. Po\u010d\u00edta\u010d som zap\u00ednal p\u00e1r min\u00fat po 9:30 a lovil v kalend\u00e1ri star\u00e9 pripojenie na Jitsi, ktor\u00e9 sme \u201czrecyklovali\u201d. Podarilo sa a s Pavlom sme sa po drobn\u00fdch peripeti\u00e1ch s technikou (kamera, repro, mikrof\u00f3n) dok\u00e1zali spoji\u0165. Nesk\u00f4r sa na online pripojil e\u0161te mBorik a t\u00fdm v\u00fdpo\u010det onlajnistov pre toto stretnutie kon\u010d\u00ed.<\/p>\n\n\n\n

Pavel sa zab\u00e1val v podstate po\u010das cel\u00e9ho d\u0148a projektom ovl\u00e1da\u010dov na vysokozdvi\u017en\u00e9 voz\u00edky. Nebolo sa \u010domu \u010dudova\u0165, \u0161t\u00e1tny sviatok a pocit, \u017ee si m\u00f4\u017eeme robi\u0165 aj nepracovn\u00e9 veci sme mali len tu na Slovensku. V \u010cech\u00e1ch sa makalo \ud83d\ude42<\/p>\n\n\n\n

Po \u00favodnej chv\u00edli kl\u00e1bosenia s Pavlom sa ozvali prv\u00ed fyzick\u00ed n\u00e1v\u0161tevn\u00edci. To zvonili nov\u00e1\u010dikovia J\u00e1n so synom Pavlom. Rozlo\u017eili sa na centr\u00e1lny st\u00f4l so zauj\u00edmav\u00fdmi expon\u00e1tmi. Priniesli na stretnutie zbrusu nov\u00e9 Didaktiky – jedno M-ko a jeden Kompakt. J\u00e1n dal toti\u017e vyrobi\u0165 nieko\u013eko-kusov\u00e9 v\u00e1rky dosiek pod\u013ea n\u00e1vrhov pracne ru\u010dne prekreslen\u00fdch z p\u00f4vodn\u00fdch . Obe ma\u0161inky boli predveden\u00e9 ako – bez pripojen\u00fdch perif\u00e9ri\u00ed – funguju k plnej spokojnosti svojho kon\u0161trukt\u00e9ra. Pri teste Kompakta s pripojen\u00edm viac ako jednej perif\u00e9rie, konkr\u00e9tne kombin\u00e1cia Melodik a divIDE syst\u00e9m spadne pri snahe o spustenie \u201cRUN\u201d.<\/p>\n\n\n\n

Vysk\u00fa\u0161ali sme r\u00f4zne kusy interfejsov, ale v\u00fdsledok bol pri v\u0161etk\u00fdch testovan\u00fdch konfigur\u00e1ci\u00e1ch rovnak\u00fd. Pri pred\u013a\u017een\u00ed zbernice je zjavne syst\u00e9m n\u00e1chyln\u00fd na jej z\u00e1\u0165a\u017e.<\/p>\n\n\n\n

Nemal som poruke vo\u013en\u00fd overen\u00fd CPU od NECu, tak\u017ee som rozobral m\u00f4jho Harlequina, a vybral z neho D780-1, ktor\u00fd sme n\u00e1sledne osadili to Kompakta. Test v\u0161ak dopadol rovnako, hoc\u00ed mnoh\u00fdm z n\u00e1s sa zd\u00e1, \u017ee pr\u00e1ve tieto japonsk\u00e9 proc\u00e1ky maj\u00fa najlep\u0161ie v\u00fdsledky pri testoch stability po pripojen\u00ed r\u00f4znych \u201ckombajnov\u201d – \u010di\u017ee nekone\u010dn\u00fdch predl\u017eova\u010dov zbern\u00edc. V tejto konkr\u00e9tnej situ\u00e1cii v\u0161ak nepomohol. Dospeli sme k z\u00e1veru, \u017ee to zrejme bez posilova\u010da zbernice nebude ma\u0165 \u010falej testova\u0165. J\u00e1n sa hne\u010f po stretnut\u00ed pustil do n\u00e1vrhu. V princ\u00edpe sme uznali, \u017ee netreba vym\u00fd\u0161\u013ea\u0165 koleso, ale bude jednoduch\u0161ie \u201czrecyklova\u0165\u201d \u010do u\u017e d\u00e1vno mala vyrie\u0161en\u00e9 mechanika D40.<\/p>\n\n\n\n

\u010co \u010dert nechcel, pri laborovan\u00ed s Kompaktom a vyberan\u00ed NECu z p\u00e4tice v Harlequine sa mi na nej vytiahla a zlomila jedna no\u017ei\u010dka. Ne\u010dudo, ve\u010f to bola najlacnej\u0161ia oby\u010dajn\u00e1 p\u00e4tica z TME, ktorej kontakty vydr\u017eia tak 2-3 zasunutia a vybratia \u0161v\u00e1bu, tak\u017ee som sa mal chv\u00ed\u013eu \u010d\u00edm zab\u00e1va\u0165, k\u00fdm som ju vymenil za prec\u00edznu.<\/p>\n\n\n\n

\u010eal\u0161\u00ed fyzick\u00ed n\u00e1v\u0161ten\u00edci, ktor\u00ed dorazili na stretnuie boli – bez n\u00e1roku na poradie – Otis, Ub880d, Martin aka mATARIn a \u010ci\u017eo.<\/p>\n\n\n\n

S mATARINom sme okrem zdol\u00e1vania piviek – ke\u010f\u017ee kone\u010dne raz ne\u0161of\u00e9roval a to aj napriek tomu, \u017ee dorazil autom v r\u00e1mci zach\u00e1dzky z dovolenky v ne\u010falekom Senci – rie\u0161ili brainstorming o \u010fal\u0161om v\u00fdvoji PMI-80 Uno. Do hry prich\u00e1dza extern\u00e1 kl\u00e1vesnica so \u0161tandardn\u00fdm \u201ckalkula\u010dkov\u00fdm\u201d rozlo\u017een\u00edm kl\u00e1ves pre numerick\u00fa \u010das\u0165 a dostatok kl\u00e1ves na \u010fal\u0161ie povely, n\u00e1sledne aj 14 alebo 16 segmentov\u00fd displej. V\u00fdmena Arduina za Martinove ob\u013e\u00faben\u00e9 ESP-8266, ktor\u00e9 by hravo zvl\u00e1dlo emulova\u0165 aj Z80.<\/p>\n\n\n\n

Ub880d drtil nejak\u00fa nov\u00fa gamesku na TT-GO VGA ZX Emul\u00e1tore s podporou emul\u00e1cie divIDE. Ak ma pam\u00e4\u0165 neklame, toto u\u017e bola nov\u0161ia verzia emul\u00e1tora ako sme videli na DR Cone a dostali sme ju nakoniec aj na USB k\u013e\u00fa\u010diku, aby sme si ju vysk\u00fa\u0161ali sami na na\u0161ich TT-GO. Prizn\u00e1vam, \u017ee som sa k tomu zatia\u013e nedostal<\/p>\n\n\n\n

S Otisom sme sa kone\u010dne dostali k testovaniu zvukov\u00e9ho interface pre QL s n\u00e1padit\u00fdm n\u00e1zvom QSound QPrint. Probl\u00e9my, ktor\u00e9 pri o\u017eivovan\u00ed zaznamenal boli sp\u00f4soben\u00e9 t\u00fdm, \u017ee poctivo n\u00e1sledoval zoznam s\u00fa\u010diastok a osadil tak 32k EPROM pod\u013ea neho, \u010do sa v\u0161ak uk\u00e1zalo ako nespr\u00e1vne rie\u0161enie. Tr\u00e1penie n\u00e1m ukon\u010dila 28C64, ktor\u00fa sme vymenili namiesto p\u00f4vodnej 27256. Jeho kus n\u00e1m u\u017e robil rados\u0165. To sa v\u0161ak nedalo poveda\u0165 o tom mojom. Postupn\u00fdm prehadzovan\u00edm \u010dipov sme sa dopracovali k zdroju probl\u00e9mu – MH74ALS03, ke\u010f sme ju vymenili za SN74LS03 alebo len za oby\u010dajn\u00fa MH7403 tak sa aj moja doska rozbehla.<\/p>\n\n\n\n

Merali sme aj zdroj k Didaktiku Gama, kde sme chceli spusti\u0165 diagnostiku. Aj ke\u010f boli na v\u00fdstupe zdroja napr\u00e1zdno spr\u00e1vne nap\u00e4tia, Gama nenabehla. Nezasvietila sa ani LED, tak\u017ee padlo podozrenie na zhoren\u00fd tranzistor alebo Zenerku v obvode stabiliz\u00e1tora. Stretol som u\u017e aj s t\u00fdm, \u017ee ne\u00famerne st\u00fapol prechodov\u00fd odpor tienen\u00fdch k\u00e1blov od zdroja, zrejme kv\u00f4li oxid\u00e1cii vodi\u010dov a napriek spr\u00e1vnym nap\u00e4tiam napr\u00e1zdno sa pri z\u00e1\u0165a\u017ei zn\u00ed\u017eili na desatiny voltu.<\/p>\n\n\n\n

Ak ma pam\u00e4\u0165 neklame, k rozobratiu Gamy sme sa nedostali, tak\u017ee sme t\u00fato te\u00f3riu nemohli overi\u0165 a nechali sme to na \u010fal\u0161iu pr\u00edle\u017eitos\u0165.<\/p>\n\n\n\n

Otis tie\u017e priniesol zop\u00e1r ISA kariet na otestovanie a pr\u00edpadn\u00e9 zabudovanie do novopostaven\u00fdch 386\/486, ktor\u00e9 za\u010d\u00ednaj\u00fa by\u0165 aktu\u00e1lnou retro platformou. \u010ci u\u017e s\u00fa to Penti\u00e1 I alebo II v Slote 1? Kto sa v tom m\u00e1 vyzna\u0165? Ako by to bolo v\u010dera \u010do som tak\u00e9to ma\u0161iny skladal ako aktu\u00e1lne kompy v \u201890-tkach. A u\u017e je to tu zas \ud83d\ude42<\/p>\n\n\n\n

Na obed sme mali \u0161pek\u00e1\u010dky so slaninkou a cibu\u013ekou pe\u010den\u00e9 v r\u00fare a podlievan\u00e9 pivkom. Trochu in\u00fd recept na ak\u00fd sme zvyknut\u00ed z DRconu, ale bolo \u00fa\u010dastn\u00edkmi potvrden\u00e9, \u017ee ani toto nemalo chybu. Niektor\u00ed si pridali aj dvakr\u00e1t. D\u00fafam, \u017ee padlo na \u00fa\u017eitok.<\/p>\n\n\n\n

\u010ci\u017eo sa zastavil iba na kr\u00e1tko aj preto sme mu s Martinom zabudli spomen\u00fa\u0165 nasleduj\u00face pivo napl\u00e1novan\u00e9 na \u0161tvrtok, ktor\u00e9 sa dohodlo predt\u00fdm ako pri\u0161iel.<\/p>\n\n\n\n

Schy\u013eovalo sa k ve\u010deru a postupne sme balili a mnoho \u00fa\u010dastn\u00edkov sa vytratilo. No zdrav\u00e9 jadro sa po ukon\u010den\u00ed dielenskej \u010dinnosti presunulo na ve\u010deru do ne\u010falekej re\u0161taur\u00e1cie \u201cPod hru\u0161kou\u201d. Tam sme si vychutnali miestne hamb\u00e1\u010de a in\u00e9 \u0161peciality pri ve\u013ekom stole spolu s Martinov\u00fdmi spolu-dovolenk\u00e1rm<\/p>\n\n\n\n

Po\u010das cel\u00e9ho stretnutia sme si u\u017eili ve\u013ea kecania, z\u00e1bavy, smiechu a pohody.<\/p>\n\n\n\n
