Tentokr\u00e1t malo stretnutie pomerne pomal\u00fd n\u00e1beh.<\/span><\/p>\n

<\/p>\n

Do upratovania dielne som sa pustil a\u017e v nede\u013eu r\u00e1no tesne pred pl\u00e1novan\u00fdm pr\u00edchodom \u00fa\u010dastn\u00edkov. Mal som obavy \u010di to stihnem, k\u00fdm sa objavia. Ofici\u00e1lny za\u010diatok bol o deviatej, no e\u0161te o pol desiatej som behal s vys\u00e1va\u010dom a odstra\u0148oval z podlahy v\u0161etky di\u00f3dy, ktor\u00e9 si b\u00f4\u017eik nestihol zobra\u0165.<\/span><\/p>\n

Pred desiatou kone\u010dne zabrumkal mobil. \u00c1, hovor\u00edm si – prv\u00fd n\u00e1v\u0161tevn\u00edk. Ale kde\u017ee, to len z00m hl\u00e1si pr\u00edchod do pol hodiny. <\/span><\/p>\n

Zasadol som za st\u00f4l a rozbalil rozobrat\u00fa klubov\u00fa +2A. Asi 20 min\u00fat pred jeden\u00e1stou vol\u00e1 Busy, vraj bl\u00fadi po okol\u00ed u\u017e 50 min\u00fat. R\u00fdchlo ho donavigujem a kone\u010dne nie som v klubovni s\u00e1m. \u010eal\u0161\u00ed prich\u00e1dza z00m. Ke\u010f sa rozbal\u00ed a usad\u00ed, Busy m\u00f4\u017ee za\u010da\u0165 pl\u00e1novan\u00fa predn\u00e1\u0161ku. Vytiahne vytla\u010den\u00fd zdroj\u00e1k a vysvet\u013euje n\u00e1m ako funguje jeho hudobn\u00e9 hradlo v 1k intr\u00e1ch. Niet nad poctiv\u00fd papierov\u00fd listing.<\/span><\/p>\n

Z00m objednal \u010fal\u0161\u00ed zauj\u00edmav\u00fd k\u00fasok, ktor\u00fd so sebou priniesol. Hne\u010f ako som sa dozvedel o novom pr\u00edrastku v ZX dzindz\u00edkoch s n\u00e1zvom \u201c<\/span>Speccy Breadboard<\/span><\/a>\u201d napadlo mi zapojenie, ktor\u00e9 som chcel d\u00e1vnej\u0161ie odprototypova\u0165: zobrazova\u010d farby BORDERu na RGB LED. Stru\u010dne si zrekapitulujme te\u00f3riu. Z\u00e1pis na spodn\u00e9 3 bity portu 254 (ako aj ka\u017ed\u00e9ho in\u00e9ho p\u00e1rneho portu, \u010di\u017ee pri A0=0, \/IORQ=0 a \/WR=0) nastav\u00ed farbu BORDERu na jednu zo siedmych mo\u017en\u00fdch, pri\u010dom bit D0 ovl\u00e1da modr\u00fa zlo\u017eku, D1 \u010derven\u00fa a D2 zelen\u00fa. Navrhli sme preto nasledovn\u00fa sch\u00e9mu: v \u00falohe dekod\u00e9ru stavov riadiacich sign\u00e1lov 74xx138, ako z\u00e1chytn\u00fd register vyhovie 74xx175. K di\u00f3de e\u0161te 3 odpory a \u0161ou sa m\u00f4\u017ee za\u010da\u0165.<\/span><\/p>\n

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

Popri os\u00e1dzan\u00ed s\u00fa\u010diastok a prepojov, Busy spom\u00ednal ako chcel zamladi vyrobi\u0165 zobrazova\u010d z 10×10 \u017eiaroviek a potom mu dakto povedal, \u017ee existuj\u00fa 7 segmentovky.<\/span><\/p>\n

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

N\u00e1sledne pri\u0161li \u010fal\u0161\u00ed \u00fa\u010dastn\u00edci stretnutia – Billy, ub880d a ellvis. <\/span><\/p>\n

Billy po pr\u00edchode rozbalil Didaktik M + SAA a p\u00fa\u0161\u0165al muziku na mal\u00fdch Genius repr\u00e1\u010dikoch, ktor\u00e9 napodiv vcelku dobre hrali.<\/span><\/p>\n

Ub rozbalil laptop a pustil emul\u00e1tor. Ako s\u00e1m nesk\u00f4r zhodnotil – po\u010das stretnutia pre\u0161iel opicu, najedol sa a zapil to kaktusom.<\/span><\/p>\n

Ja som sa p\u00f4vodne chcel pusti\u0165 do dokon\u010denia klubovej +2A (ktor\u00e1 sa mimochodom po pridan\u00ed floppy radi\u010da od ellvisa tv\u00e1ri ako +3) alebo doos\u00e1dzania Z-Berry, ale nakoniec sme na jedinom letovacom pracovisku rozbalili z00move 8\u201d zobrazovadlo \u010d\u00ednskej v\u00fdroby. Pre chyby v zobrazovan\u00ed v dolnej \u010dasti obrazovky sme podozrievali hlavn\u00fd \u0161v\u00e1b MST705 no po jeho v\u00fdmene zobrazovadlo u\u017e ne\u0161lo zapn\u00fa\u0165 v\u00f4bec. <\/span><\/p>\n

Us\u00fadili sme, \u017ee je \u010das na prest\u00e1vku a za\u010dali prem\u00fd\u0161\u013ea\u0165 \u010do s obedom. Vo\u013eba padla na \u010d\u00ed\u0148ana, ktor\u00fd minule sklamal, lebo mal zatvoren\u00e9. Sk\u00fasili sme to teda znovu a tentokr\u00e1t to vy\u0161lo. Bohat\u00e9 porcie a polievka v cene hlavn\u00e9ho jedla si vy\u017eiadali svoju da\u0148. Aspo\u0148 u m\u0148a t\u00e1to kombin\u00e1cia vyvolala neskuto\u010dn\u00fd \u00fatlm, tak\u017ee som poobede len tak odfukoval a debatil.<\/span><\/p>\n

E\u0161te som raz obehol c\u00ednom 100 pinov MST705 a telku sa podarilo zapn\u00fa\u0165. \u017dia\u013e vykazovala tie ist\u00e9 defekty ako pred v\u00fdmenou IO. Pohrali sme sa e\u0161te trochu so vstupn\u00fdmi odde\u013eovac\u00edmi kondenz\u00e1tormi. Sk\u00fasili ich zv\u00e4\u010d\u0161i\u0165 na dvojn\u00e1sobok, pr\u00edpadne \u00faplne vynecha\u0165, ale \u017eiadna z t\u00fdchto \u00faprav nemala blah\u00fd vplyv na kvalitu obrazu. N\u00e1sledne sme vr\u00e1tili dosku do p\u00f4vodn\u00e9ho stavu.<\/span><\/p>\n

Po\u010das poobedn\u00e9ho debatenia ellvis spomenul, \u017ee bude meni\u0165 robotu a v\u010faka tomu m\u00e1 vo\u013en\u00fd september, tak\u017ee by sa znova mohol zastavi\u0165 na SinDiKate. Tie\u017e porozpr\u00e1val o svojich pl\u00e1noch rozbehn\u00fa\u0165 tla\u010diare\u0148. Ako\u017ee nie BT100, ale profesion\u00e1lnu prev\u00e1dzku na v\u00fdrobu \u010dasopisov a in\u00fdch tla\u010dov\u00edn. Ja som sa mu sna\u017eil nan\u00fati\u0165 Centronics konektory, ktor\u00e9 som medzi\u010dasom pozh\u00e1\u0148al pre CPC\u010dk\u00e1rov, ale povedal, \u017ee mikezt to u\u017e m\u00e1 vyrie\u0161en\u00e9 a \u010fal\u0161ie konektory nepotrebuje. Ni\u010d to, odlo\u017e\u00edm ich na hor\u0161ie \u010dasy.<\/span><\/p>\n

\u010ealej to zbehlo podozrivo r\u00fdchlo. Chlapi odk\u00e1zan\u00ed na hromadn\u00e9 spoje (Busy a ub) sa za\u010dali vytr\u00e1ca\u0165 okolo \u0161tvrtej. Nasledoval ich ellvis, ktor\u00e9ho \u010dakala dlh\u00e1 cesta. <\/span><\/p>\n

P\u00e1r min\u00fat po piatej som \u0161iel odprevadi\u0165 pred br\u00e1nu poslen\u00fdch \u00fa\u010dasnt\u00edkov (Billy a z00m).<\/span><\/p>\n

Z\u00e1vere\u010dn\u00e9 t\u00e9my, ktor\u00e9 sme tam prebrali boli \u00faplne nepo\u010d\u00edta\u010dov\u00e9. Z00m predviedol ter\u00e9nne aut\u00ed\u010dko na dia\u013ekov\u00e9 ovl\u00e1danie a uk\u00e1zal ak\u00e9 k\u00fasky zvl\u00e1da. Vyjazdil dve bat\u00e9rie a po\u010das jedn\u00e9ho nebezpe\u010dn\u00e9ho man\u00e9vru sa rozhasilo servo na riaden\u00ed, tak\u017ee aut\u00ed\u010dko odkladal s t\u00fdm, \u017ee bude ma\u0165 doma \u010do opravova\u0165. N\u00e1sledne sa debata strhla na fenom\u00e9n doby pre na\u0161e deck\u00e1 – fidget spinnery. Pos\u0165a\u017eovali sme si, ako je \u0165a\u017ek\u00e9 zohna\u0165 spr\u00e1vne lo\u017eisk\u00e1 a ko\u013eko r\u00f4znych modelov sme u\u017e museli deck\u00e1m vytla\u010di\u0165.<\/span><\/p>\n

A\u017e na nekres\u0165ansky vysok\u00fa teplotu vonku a nesk\u00f4r aj vn\u00fatri sa stretnutie skuto\u010dne vydarilo.\u00a0<\/span>Bolo pr\u00edjemn\u00e9 op\u00e4\u0165 vidie\u0165 chalanov pri plnom zdrav\u00ed a sile. Viem o \u010dom hovor\u00edm, lebo som si musel minul\u00fd mesiac pobudn\u00fa\u0165 doma po ne\u0161\u0165astnom p\u00e1de z bicykla a t\u00fdm p\u00e1dom odoprie\u0165 napr. aj DRCon.<\/span><\/p>\n

Te\u0161\u00edm sa \u010fal\u0161ie stretnutie.<\/span><\/p>\n
