Predminul\u00fa sobotu sme sa stretli piati, ale iba \u0161tyria sme tr\u00e1vili v\u00e4\u010d\u0161inu \u010dasu v klubovni.<\/p>\n

 <\/p>\n

Sobotn\u00e9 r\u00e1no za\u010dalo dos\u0165 ak\u010dne. Mal som dohodnut\u00fd odvoz reziva, z ktor\u00e9ho pl\u00e1nujem vybudova\u0165 pri dome p\u00edstre\u0161ok na terasu a tie\u017e diel\u0148u, tak\u017ee namiesto rannej rozcvi\u010dky sme nakladali 3 kub\u00edky dreva v ne\u010falekom drevoobchode<\/a>. Po prevoze k domu sa objavil \u010ci\u017eo, ktor\u00fd n\u00e1m pomohol s vykladan\u00edm a tak sa \u010das tejto \u010dinnosti v\u00fdrazne skr\u00e1til oproti nakladaniu. Po takomto v\u00fdkone sme sa museli posilni\u0165, tak\u017ee pri\u0161li na rad neskor\u0161ie ra\u0148ajky a vyrazili sme vo dvojke do Smolen\u00edc. Billy n\u00e1s musel \u010daka\u0165, lebo ak\u010dn\u00e9 \u201cdreven\u00e9\u201d r\u00e1no, vyzdvihnutie k\u013e\u00fa\u010dov od klubovne u Z00ma a\u00a0 \u010ci\u017eova n\u00e1v\u0161teva smolenick\u00fdch potrav\u00edn n\u00e1m kumulat\u00edvne sp\u00f4sobila asi 40 min\u00fatov\u00e9 zdr\u017eanie.<\/p>\n

Ke\u010f sme kone\u010dne dorazili, zaregistrovali sme, \u017ee Billy u\u017e spratal zo stolov obrusy a sedel osamotene v rohu s dvomi Didaktikmi. Jedno bolo \u0161peficiky upraven\u00e9 Mko s RGB v\u00fdstupom, ktor\u00fd vyzeral by\u0165 montovan\u00fd priamo vo v\u00fdrobnom z\u00e1vode. Druh\u00e1 bola Gama s prapodivn\u00fdm doroben\u00fdm hardv\u00e9rom, \u0161tyrmi DIP switchmi na hornom kryte a p\u00e4\u0165kol\u00edkom na boku. Pod vrstvami izola\u010dky sa skr\u00fdval vraj D\/A prevodn\u00edk MDAC08C a tie\u017e boli d\u00e1ke \u0161v\u00e1by doletovan\u00e9 na p\u00f4vodn\u00e9 LS-TTL okolo 8255 s vyhnut\u00fdmi no\u017ei\u010dkami o 90 stup\u0148ov okrem nap\u00e1jac\u00edch pinov. Na vyhnut\u00e9 piny boli na\u0165ahan\u00e9 smaltovan\u00e9 dr\u00f4tiky. Pod\u013ea m\u0148a typick\u00fd \u0161t\u00fdl \u00faprav z 90-tych rokov. \"dm_rgb1\"<\/a> \"dm_rgb2\"<\/a> \"dm_rgb3\"<\/a> \"dg1\"<\/a><\/p>\n

Po pr\u00edchode a zbe\u017enom prezret\u00ed t\u00fdchto k\u00faskov som\u00a0 za\u010dal pomaly nosi\u0165 veci z klubov\u00e9ho \u201cskladu\u201d – internetov\u00e9 AP, telku, pred\u013a\u017eova\u010dku, HxC floppy emul\u00e1tor, \u010diasto\u010dne kanibalizovan\u00fa dosku Commodore PC-I na uk\u00e1\u017eku Billymu at\u010f.
\nZa nejak\u00fa chv\u00ed\u013eu sme mali mo\u017enos\u0165 op\u00e4\u0165 sa stretn\u00fa\u0165 so Z00mom, ktor\u00fd priviezol do are\u00e1lu Ub880d-ho.<\/p>\n

Ako prim\u00e1rny stroj som si rozlo\u017eil repasovan\u00fd gum\u00e1k, ktor\u00fd som zak\u00fapil od ma\u010farsk\u00fdch spektristov na tohtoro\u010dnom Foreveri. Gum\u00e1k m\u00e1 ve\u013emi zachoval\u00fd exteri\u00e9r, ale vo vn\u00fatornostiach pre\u0161iel kompletnou rekon\u0161trukciou. Namiesto p\u00f4vodnej, nefunk\u010dnej a prerobenej Issue 3B je tam teraz doska Harelquina a nov\u00e1 \u201cstaro-skladov\u00e1\u201d membr\u00e1na, ktor\u00fa som tie\u017e k\u00fapil v S\u00fa\u010di od LCD-ho. Striedavo som zap\u00e1jal k spektru dve rozdvojky, pri\u010dom som mal v ka\u017edej zapichnut\u00e9 r\u00f4zne perif\u00e9rie. Jedna dvojica bola divIDE a Simple AY. Pri tejto konfigur\u00e1cii sme si pozreli zop\u00e1r 48k dem. Potom som rozdvojku prehodil. Na tej druhej bolo nave\u0161an\u00e9 divIDE a ZX UPI, aby sme mohli otestova\u0165 tla\u010diare\u0148 HP DeskJet 340, ktor\u00fa SinDiKat dostal do daru na Foreveri od Solarisa. Ako to u\u017e pri atramentov\u00fdch tla\u010diar\u0148ach b\u00fdva, najv\u00e4\u010d\u0161ou slabinou s\u00fa n\u00e1hradn\u00e9 n\u00e1plne. Hoci boli k tla\u010dke pribalen\u00e9 v tomto pr\u00edpade a\u017e 2, boli u\u017e vyminut\u00e9 alebo zaschnut\u00e9 a pou\u017ei\u0165 sa nedali. To sme otestovali u\u017e na Foreveri. Ja som na zh\u00e1\u0148anie novej n\u00e1plne akosi pozabudol a term\u00edn stretnutia sa bl\u00ed\u017eil, tak\u017ee som ju vo \u0161tvrtok na z\u00e1klade \u010ci\u017eovho tipu nakoniec objednal za rozumn\u00fa cenu a s nulovou cenou za dopravu. Firma<\/a>, ktor\u00e1 ju pred\u00e1vala mala na str\u00e1nke uveden\u00e9, \u017ee pokia\u013e stihnem odosla\u0165 objedn\u00e1vku do 16.00, z\u00e1sielka bude doru\u010den\u00e1 na \u010fal\u0161\u00ed de\u0148. A naozaj sa tak stalo. V piatok poobede zazvonil kuri\u00e9r a n\u00e1pl\u0148 doniesol. Pri\u0161la teda tak povediac cez noc.\u00a0 Vyd\u00fdchol som si, \u017ee v sobotu budeme m\u00f4c\u0165 testova\u0165.<\/p>\n

Na za\u010diatok sme zalo\u017eili n\u00e1pl\u0148, papier a tla\u010diare\u0148 pripojili k laptopu HP nc6000, ktor\u00fd m\u00e1 aj klasick\u00fd paraleln\u00fd port. Nain\u0161talovan\u00fd Windows mal v\u0161ak nastaven\u00fa farebn\u00fa tla\u010dov\u00fa n\u00e1pl\u0148 ako v\u00fdchodziu, tak\u017ee prv\u00e1 strana vyliezla pomerne nevydaren\u00e1. Vyzeralo to, ako by atrament robil \u010dmuhy po papieri. Potom som prehodil v ovl\u00e1da\u010di typ nain\u0161talovanej n\u00e1plne a vysk\u00fa\u0161al vytla\u010di\u0165 text namiesto grafiky (\u201ccopy con lpt1:\u201d v pr\u00edkazovom riadku). Tento v\u00fdstup u\u017e vyzeral omnoho pou\u017eite\u013enej\u0161ie.
\nPotom sa LPT k\u00e1bel prehodil do ZX UPI a mohlo za\u010da\u0165 testovanie tla\u010de zo spektr\u00e1\u010da.
\nTu sa v\u00fdrazne realizovali Ub880d s Billym. Spolo\u010dne pripravovali najprv basicov\u00fd test, n\u00e1sledne pracovali na pridan\u00ed spr\u00e1vneho ovl\u00e1da\u010da do Desktopu a konverzii loga SinDiKatu ako s\u00e9rie obr\u00e1zkov do s\u00faboru pre Desktop.<\/p>\n

\"zx_desktop3\"<\/a> \"zx_desktop4\"<\/a>\"zx_desktop2\"<\/a> \"zx_desktop1\"<\/a>\u010ci\u017eo priniesol na stretnutie dva m\u0155tve laptopy HP nc6000 a Compaq Presario M2000. Ve\u013emi sa pozab\u00e1val pri rozborke a zborke oboch k\u00faskov. Ke\u010f sa mu poradilo z ka\u017ed\u00e9ho vytiahnu\u0165 mainboard pri\u0161la na rad moja \u010das\u0165 \u00falohy – obtiahnu\u0165 nap\u00e1jacie \u010dipy olovnatou sp\u00e1jkou, lebo za dlh\u00e9 roky pou\u017e\u00edvania sa tepeln\u00fdm nam\u00e1han\u00edm v bezolovnatej vytvorili mikrotrhliny. V oboch pr\u00edpadoch oper\u00e1cia dopadla \u00faspe\u0161ne a po op\u00e4tovnom zlo\u017een\u00ed – daktor\u00fdch aj opakovane z d\u00f4vodu \u201czabudnut\u00e9ho k\u00e1bliku\u201d – ma\u0161inky nabehli.<\/p>\n

\"laptopy1\"<\/a> \"laptopy2\"<\/a>Na z\u00e1ver mi pod ruky op\u00e4\u0165 pri\u0161la doska Issue 3B, ktor\u00e1 bola p\u00f4vodn\u00fdmi vn\u00fatornos\u0165ami gum\u00e1ka. Doletov\u00e1val som blokovacie kondenz\u00e1tory na VRAM \u010dipy a testoval impulzn\u00fd zdroj s alternat\u00edvnym \u010dipom MP1584<\/a>, ktor\u00fd je ud\u00e1van\u00fd ako n\u00e1hrada LM2596. Pri pr\u00fade, ktor\u00fd pap\u00e1 ZX a po\u017ei\u010danom 9V zdroji od Billyho bol \u00fabytok nap\u00e4tia pr\u00edli\u0161 ve\u013ek\u00fd – na VRAM iba 4V – a IO stabiliz\u00e1tora v p\u00fazdre SOIC8 bez dodato\u010dn\u00e9ho chladenia sa v\u00fdrazne prehrieval. Po\u010dk\u00e1m si teda na objednan\u00e9 moduly s v\u00fdkonnej\u0161\u00edm LM2596 a prehod\u00edm to.<\/p>\n

Obed sme objedn\u00e1vali \u0161tandardne od Halen\u00e1ra. Dovoz robila celkom sympatick\u00e1 sle\u010dna, ktor\u00e1 v\u0161ak s\u010dasti stratila na\u0161e sympatie, ke\u010f polo\u017eila nevhodn\u00fa ot\u00e1zku – nie\u010do v zmysle \u201cA to si neviete navari\u0165 sami?\u201d. My s\u00edce vieme, \u017ee sme \u0161ikovn\u00ed a preto st\u00e1le zanepr\u00e1zdnen\u00ed bastlen\u00edm namiesto varenia, ale m\u00f4\u017eeme za to? Navy\u0161e takto n\u00e1s podceni\u0165 \ud83d\ude42<\/p>\n

\u010casu na v\u0161etky aktivity bolo op\u00e4\u0165 menej ako by sme vedeli vyu\u017ei\u0165, ale stretnutie pova\u017eujem za mimoriadne vydaren\u00e9 z poh\u013eadu toho, \u010do sme v\u0161etko dok\u00e1zali stihn\u00fa\u0165 rozbeha\u0165 a opravi\u0165.<\/p>\n

Te\u0161\u00edm sa na bud\u00face.<\/p>\n
