Zop\u00e1r postrehov zo sveta \u201ckonkurencie\u201d. Len \u017eiadny strach, v\u0161etko \u010falej popisovan\u00e9 m\u00e1 bu\u010f osembitov\u00fa zbernicu alebo aspo\u0148 nesie logo Sinclair.<\/p>\n\n\n\n\n\n\n\n

PC200, \u010do je vlastne posledn\u00fd po\u010d\u00edta\u010d ozna\u010den\u00fd p\u00f4vodn\u00fdm ofici\u00e1lnym logom Sinclair za akt\u00edvnej \u00e9ry tejto zna\u010dky v 80-tych rokoch, bol spomenut\u00fd u\u017e v minul\u00fdch z\u00e1piskoch<\/a>. Roz\u0161iroval som mu vtedy RAMku a repasoval membr\u00e1nov\u00e9 pr\u00edvody kl\u00e1vesnice.<\/p>\n\n\n\n

Nasledovala v\u00fdmena p\u00f4vodnej nefunk\u010dnej disketovky za Gotek, aby som sa nadobro vyhol diskot\u00e9ke, lebo ma\u0161ina iba s jedn\u00fdm flop\u00e1kokm naozaj nie je dnes \u017eiadna sl\u00e1va.<\/p>\n\n\n\n

Povedzme si otvorene, to nebola ani v dobe uvedenia tohto modelu na trh. U\u017e vtedy zo\u017eal vlnu kritiky nielen za parametre, ktor\u00e9 boli na \u00farovni o sedem rokov star\u0161ieho IBM PC XT – mo\u017eno s v\u00fdnimkou r\u00fdchlej\u0161ieho CPU, ale aj za sp\u00f4sob ak\u00fdm sa d\u00e1 roz\u0161irova\u0165. <\/p>\n\n\n\n

Dva osembitov\u00e9 sloty skr\u00fdvaj\u00face sa pod krytom, ktor\u00fd sa mus\u00ed natrvalo odmontova\u0165, aby sa dali osadi\u0165 dodato\u010dn\u00e9 karty. M\u00f4j kus pre istotu tento kryt nemal v\u00f4bec, zrejme sa stratil vo v\u00edre dej\u00edn. Roz\u0161irovaniu po\u010d\u00edta\u010da sa v\u0161ak nevyhneme, aby  sa ma\u0161ina stala ako-tak pou\u017eite\u013enou.<\/p>\n\n\n\n

Pre m\u0148a sa tak DOScember<\/a> presunul a\u017e na janu\u00e1r, kedy mi z \u010ciny do\u0161li DPS na XTIDE, konkr\u00e9tne na verziu XT CF Lite V4<\/a>. Dosku som osadil za jedno poobedie a popri tom som narazil iba na jeden probl\u00e9m – konkr\u00e9tne s CF slotom, lebo Sergej pou\u017eil in\u00fd typ ako sa os\u00e1dza do MSX Carnivore, ktor\u00fd som mal e\u0161te v dom\u00e1cich z\u00e1sob\u00e1ch. Tak\u017ee som musel zreza\u0165 vymedzovacie plastov\u00e9 cupl\u00edky, aby cel\u00fd slot nevy\u010dnieval nad dosku. Po optickej kontrole a otestovan\u00ed v sk\u00fa\u0161obnej PC doske som sa odv\u00e1\u017eil kartu zasun\u00fa\u0165 do PC200. Nasledovalo jumprovanie a flashovanie XT Universal BIOSu a so spr\u00e1vnymi nastaveniami – IO port 0x300h a adresou za\u010diatku na D800h sa BIOS prihl\u00e1sil, len sa nepodarilo z CF karty nabootova\u0165.\u00a0<\/p>\n\n\n\n

Jej pr\u00edpravu som robil samozrejme v \u010d\u00edta\u010dke pod Windows a myslel som si, \u017ee FAT16 je FAT16 za ka\u017en\u00fdch okolnost\u00ed,  ale MS-DOS 5 to nehodlal akceptova\u0165, k\u00fdm som form\u00e1tovanie, ale hlavne povestn\u00fd `fdisk \/mbr<\/code>` neurobil pr\u00e1ve z neho. Potom som si u\u017e mohol naplno u\u017e\u00edvat radosti pou\u017e\u00edvania syst\u00e9mu vybaven\u00e9ho jednotkou \u201cC:\u201d. Znenazdajky sa v druhej polovici janu\u00e1ra objavila aj verzia Wolfensteina 3D, ktor\u00e1 be\u017e\u00ed na CGA a XT, a tak som si nenechal ujs\u0165 pr\u00edle\u017eitos\u0165 5MB demo na PC200 zahra\u0165. R\u00fdchlos\u0165ou teda naozaj neopl\u00fdva, ale v\u010faka existencii disku ho bolo mo\u017en\u00e9 aspo\u0148 spusi\u0165.<\/p>\n\n\n\n

Origin\u00e1lnu my\u0161 k PC200, ktor\u00e1 sa prip\u00e1ja na dedikovan\u00fd port, nem\u00e1m, ale s redukciou DB9 na DB25 mi bezprobl\u00e9movo funguje \u0161\u0165andardn\u00e1 Genius my\u0161 na s\u00e9riov\u00fd port. Ako ovl\u00e1da\u010d pou\u017e\u00edvam CuteMouse z FreeDOSu. Otestoval som si tie\u017e pripojenie anal\u00f3gov\u00e9ho joysticku na game port a v CheckIte som overil jeho funk\u010dnos\u0165.<\/p>\n\n\n\n

Pre zlep\u0161enie umeleck\u00e9ho dojmu \u010dak\u00e1m e\u0161te na dod\u00e1vku dosiek a komponentov na AdLib<\/a> kartu a t\u00fdm zrejme skompletizovanie zostavi\u010dky funk\u010dn\u00e9ho XT s logom na\u0161ej ob\u013e\u00fabenej zna\u010dky zav\u0155\u0161im.<\/p>\n\n\n\n

Predchodcom PC200 v kateg\u00f3rii XT v mojej zbierke bolo Sanyo MBC-16LT<\/a>, ktor\u00e9 m\u00e1 osaden\u00e9 dve mechaniky a jeho s\u00fa\u010das\u0165ou je aj zabudovan\u00fd monochromatick\u00fd nepodsvieten\u00fd LCD displej s CGA rozl\u00ed\u0161en\u00edm.<\/p>\n\n\n\n

V\u00fdrobca toti\u017e zabudol na dosku osadi\u0165 konektor na roz\u0161iruj\u00faci slot.<\/p>\n\n\n\n

Zostal som tak mierne zasko\u010den\u00fd \u00falohou ako si spust\u00edm Wolfensteina 3D na tejto konfigur\u00e1cii. K dispoz\u00edcii je v\u0161ak be\u017en\u00fd paraleln\u00fd port, tak\u017ee rie\u0161enie, ktor\u00e9 sa pon\u00faka by mohla by\u0165 ZIP alebo JAZ mechanika, pr\u00edpadne ak by sa niekde dal zohna\u0165 vyn\u00e1lez s n\u00e1zvom ParaDisk<\/a>. Ni\u010d tak\u00e9 som ale poruke  nemal, preto som trochu zaimprovizoval a vyrobil si za poobedie \u010d\u00edta\u010dku kariet na LPT port s n\u00e1zvom SDLPT<\/a> (n\u00e1stupca SDPPD<\/a>).<\/p>\n\n\n\n

V\u00fdpo\u010det XT\u010diek, na ktor\u00fdch si viem spusti\u0165 Wolfensteina 3D v CGA verzii by nebol kompletn\u00fd, keby som nespomenul palmtopy HP 200LX a OmniGo 700LX.
