V porad\u00ed u\u017e piate stretnutie malo zauj\u00edmav\u00fd priebeh.Na \u00favod som sa za\u010dal venova\u0165 Issue 2, ktor\u00e9 m\u00e1m v pluskovej krabici.
Ma\u0161ine vypad\u00e1vali farby na TV, ke\u010f bola pripojen\u00e1 cez kompozitn\u00fd videosign\u00e1l.
V tejto verzii Speccy je star\u00e1 ULA a zrejme preto je v anal\u00f3govej \u010dasti potrebn\u00e9 nastavenie niektor\u00fdch sign\u00e1lov.
Na doske s\u00fa kv\u00f4li tomu osaden\u00e9 2 potenciometre 2K2 (VR1 a VR2) a a kapacitn\u00fd trimer (TC2).<\/p>\n

Zmenou ich hodn\u00f4t sa mi podarilo doladi\u0165 obraz ako tak do uspokojiv\u00e9ho stavu, hoci biela mala st\u00e1le n\u00e1dych do \u017elta.
Navy\u0161e po natiahnut\u00ed hry z divIDE + CF sa farby z\u00e1hadne str\u00e1cali. Povedal som si, \u017ee toto bude vy\u017eadova\u0165 vysk\u00fa\u0161anie aj na inej TV a rad\u0161ej som to zabalil.<\/p>\n

\u00a0<\/p>\n

Najviac \u010dasu z posledn\u00e9ho stretnutia som venoval mazac\u00edm a programovac\u00edm cyklom EPROM. So z00mom sme sa zlo\u017eili na lacn\u00fd maza\u010d z eBay.
Ani som ned\u00fafal, \u017ee to za tie peniaze bude spo\u013eahlivo fungova\u0165, nu\u017e ale aj \u010d\u00ednski s\u00fadruhovia vedia ob\u010das prekvapi\u0165.
Vymazali sme hafo pam\u00e4t\u00ed asi 15-20 minutov\u00fdmi cyklami. Asi 2 ks bolo treba maza\u0165 viac kr\u00e1t, lebo po prvom zmazan\u00ed mali st\u00e1le niektor\u00e9 bity v 0.
Potom sme nap\u00e1lili nejak\u00e9 27C128 so spektr\u00e1ckou ROMkou a 27C256 so 128k ROM.
Ako posledn\u00e9 som p\u00e1lil EPROMy do mojej +3, ktor\u00fa som sa na posledn\u00fa chv\u00ed\u013eu rozhodol prerobi\u0165 na +3e. Chalani boli tak\u00ed l\u00e1skav\u00ed a stiahli mi z netu spr\u00e1vny ZIP, kde boli obsahy jednotliv\u00fdch EPROM.<\/p>\n

Napodiv, po v\u00fdmene p\u00f4vodn\u00fdch \u010dipov za nap\u00e1len\u00e9 27C256tky sa ma\u0161inka rozbehla a rozsvietila na obrazovke magick\u00fd n\u00e1pis 128 +3e.
z00m sa obetoval a po\u017ei\u010dal mi na chv\u00ed\u013eu svoju CFku, aby som mal \u010do naform\u00e1tova\u0165 na +3DOS format. V\u0161etko be\u017e\u00ed ako hodinky a na t\u00fato z\u00e1bavku som si vy\u010dlenil star\u00fa 32MB MMC kartu s pr\u00edslu\u0161nou redukciou do divIDE.<\/p>\n

Vysk\u00fa\u0161ali sme aj spr\u00e1vnos\u0165 nap\u00e1lenia spektr\u00e1ckej ROMky, tak \u017ee sme ju pichli do p\u00e4tice v Du\u0161kyho Game. \u00daspe\u0161ne.<\/p>\n

Menej \u00faspe\u0161n\u00e1 bola hodinka s Gamou, po\u010das ktorej som zis\u0165oval pre\u010do ULA nezobrazuje spr\u00e1vne D0 z VRAM modulu s cache pam\u00e4\u0165ou. CPU t\u00fato \u010das\u0165 pam\u00e4ti mus\u00ed vidie\u0165 spr\u00e1vne, lebo reset prebehne pod\u013ea o\u010dak\u00e1vania a basicov\u00fd program, ktor\u00fd sa tam zap\u00ed\u0161e nevykazuje \u017eiadne vady. Len ULA farb\u00ed INK na modro a kresl\u00ed na ka\u017edom bode obrazovky zodpovedaj\u00facom najni\u017e\u0161iemu d\u00e1tov\u00e9mu bitu bod = vid\u00ed tam log 1.<\/p>\n

Telemost na JHcon sa n\u00e1m podarilo zrealizova\u0165 a\u017e po men\u0161\u00edch logistick\u00fdh \u0165a\u017ekostiach, ale nakoniec sme mali mo\u017enos\u0165 pozdravi\u0165 jeho \u00fa\u010dastn\u00edkov.<\/p>\n

z00m venoval va\u010d\u0161inu \u010dasu letovaniu kade\u010doho. Po\u010das toho mi dal dokopy AY modul na m\u00f4j kombajn – v\u010faka.<\/p>\n

<\/p>\n

Du\u0161ky poctivo v\u0155tal a osadzoval plo\u0161\u00e1k na JROKa. Potom testoval r\u00f4zne dosky (Gama + ZX) vs. divIDE, ktor\u00fdm za podivn\u00fdch okolnost\u00ed\u00a0 odch\u00e1dzali farby. M\u00e1m v\u0161ak tak\u00fd pocit, \u017ee najva\u010d\u0161iu \u00falohu pri t\u00fdchto pokusoch zohral star\u00fd TV, ktor\u00fd na SinDiKate m\u00e1me. Podobne ako moje probl\u00e9my s Issue 2 pominuli, ke\u010f som ho testoval doma na inom TV.<\/p>\n

\u00a0<\/p>\n

Nairam sa sna\u017eil vysk\u00fa\u0161a\u0165 RGB v\u00fdstup zo svojej +3, \u017eia\u013e nikto nemal poruke RGB monitor.<\/p>\n

\u00a0<\/p>\n

\u010ci\u017eo kompiloval kernel na laptope, aby vysk\u00fa\u0161al ako be\u017e\u00ed EasyCAP pod Linuxom. Mysl\u00edm, \u017ee test nakoniec dopadol \u00faspe\u0161ne.
Chv\u00ed\u013eu sme si na konkuren\u010dnej platforme zadrtili International Karate + s dvomi joystickmi.<\/p>\n

\u00a0<\/p>\n

Hoci sme toto stretnutie pre\u017eili bez n\u00e1v\u0161tevy re\u0161tarura\u010dn\u00e9ho zariadenia a bez pr\u00edjmu plnohodnotn\u00e9ho jedla (kex\u00edky a sladkosti ner\u00e1tam), odch\u00e1dzali sme spokojn\u00ed a s pocitom, \u017ee sme pre na\u0161ich 8bitov\u00fdch mil\u00e1\u010dikov spravili op\u00e4\u0165 kus dobrej roboty.<\/p>\n

Te\u0161\u00edm sa na novoro\u010dn\u00e9 pokra\u010dovanie, ktor\u00e9 by sa pod\u013ea predbe\u017en\u00fdch pl\u00e1nov malo kona\u0165 9.1.2010.<\/p>\n

 <\/p>\n

\u0160\u0165astn\u00e9 a vesel\u00e9 (pokia\u013e mo\u017eno \u010do najviac 8bitov\u00e9) Vianoce a \u00faspe\u0161n\u00fd Nov\u00fd rok priaznivcom SinDiKatu praje<\/p>\n
