V sobotu 19.2. sme sa stretli po druh\u00fd kr\u00e1t vo febru\u00e1ri, tentoraz v komornom zlo\u017een\u00ed.<\/p>\n

<\/p>\n

Po dvoch t\u00fd\u017ed\u0148och od stretnutia mi \u010do-to povypad\u00e1valo z hlavy, ale z\u00e1pisky som aspo\u0148 v hrub\u00fdch rysoch dokon\u010dil.<\/p>\n

Portf\u00f3lio ma\u0161in, ktor\u00e9 sa v on\u00fa sobotu vystriedali pod rukami bolo pestr\u00e9, ale preva\u017ene pozost\u00e1valo z produkcie CZ\/SK a neboli to klony Sinclaira. Ten sa stal tak trochu okrajovou z\u00e1le\u017eitos\u0165ou.<\/p>\n

<\/p>\n

Hoci na \u00favod to vyzeralo n\u00e1dejne, lebo sme sa pustili do testovanie SIFu so ZX Issue6 (\u00faprava 128k). V\u00fdsledky boli op\u00e4\u0165 rozporupln\u00e9. Jeden z 2 SIFov funguje absol\u00fatne spo\u013eahlivo, druh\u00fd m\u00e1 st\u00e1le probl\u00e9m – z 1000 prenesen\u00ed obsahu ZX ROM mu nevyjde krok tak v 2-3 pr\u00edpadoch. D\u013a\u017eka s\u00faboru sed\u00ed, ale obsah s\u00faboru sa v nieko\u013ek\u00fdch bajtoch l\u00ed\u0161i.
\n\u010cierny prevodn\u00edk USB-serial<\/a> (SKU 24799) z DealExtreme je absol\u00fatne nepou\u017eite\u013en\u00fd a mal by letie\u0165 okam\u017eite do ko\u0161a. Pri pou\u017eit\u00ed so SIFom je d\u013a\u017eka ka\u017ed\u00e9ho prenesen\u00e9ho obrazu ROM \u00faplne in\u00e1, ale v\u017edy krat\u0161ia ako ve\u013ekos\u0165 16384 bajtov. Prehl\u00e1sili sme to za uzavret\u00e9 a vrhli sa na \u010fal\u0161ie z\u00e1le\u017eitosti.<\/p>\n

<\/p>\n

Asi najdlh\u0161iu \u010das\u0165 d\u0148a zabrali experimenty s PMD85. Jednak sme rozmontovali 3ks PMD, ktor\u00e9 priniesol Ffg. Dva kusy boli verzie 2A, hoci jeden z nich mal kl\u00e1vesnicu z jednotky. Nesk\u00f4r pri\u0161la na rad aj verzia 3.<\/p>\n

<\/p>\n

<\/p>\n

Pomerne dlh\u00fd \u010das sme sa venovali pokusom o nahr\u00e1vanie programov z MP3 prehr\u00e1va\u010da resp. zvukovky laptopu do PMD.
\nFfg op\u00e4\u0165 vyu\u017eil svoju nesporn\u00fa v\u00fdhodu, \u017ee b\u00fdva \u010do by kame\u0148om dohodil od klubu a na nieko\u013eko iter\u00e1ci\u00ed priniesol tu\u0161\u00edm 3 r\u00f4zne MP3 prehr\u00e1va\u010de na testovanie. Nakoniec sa mu podarilo n\u00e1js\u0165 jeden, z ktor\u00e9ho vyp\u00edskal do PMD \u017eaby. Ub880d sk\u00fa\u0161al vyp\u00edskava\u0165 WAVy zo svojho EEE\u010dka, Ffg podobne. Pokia\u013e ma pam\u00e4\u0165 neklame, z jedn\u00e9ho to \u0161lo a zdruh\u00e9ho ve\u013emi nie.<\/p>\n

<\/p>\n

<\/p>\n

Trochu sme sa r\u00fdpali aj v LCD monitore, ktor\u00fd sa ani nesna\u017eil nabehn\u00fa\u0165. Pravdupovediac v tejto technike sa a\u017e tak neorientujem, preto som odporu\u010dil zobra\u0165 ho na najbli\u017e\u0161iu burzu, kde by sa dal zohna\u0165 niekto, kto sa sa v tom vyzn\u00e1.<\/p>\n

Ja som sa nesmelo sp\u00fdtal, \u010di Ffg n\u00e1hodou nem\u00e1 doma v zbierke aj PP-01. Samozrejme priniesol ho v r\u00e1mci jedn\u00e9ho zo svojich v\u00fdletov domov. Klubov\u00fd TV nem\u00e1 RGB vstup, preto sme mohli ma\u0165 iba \u010diernobiely z\u00e1\u017eitok z tohto hned\u00e9ho mon\u0161tra s mierne za\u017eltnutou kl\u00e1vesnicou. Po\u010d\u00edta\u010d sa nepodarilo zapn\u00fa\u0165 na prv\u00fd pokus, ale po p\u00e1r min\u00fatach to „rozchodil“ a u\u017e sme mohli experimentova\u0165 ako sa prejav\u00ed pr\u00edkaz INK a PAPER na \u010c\/B v\u00fdstupe.<\/p>\n

<\/p>\n

Niekde k z\u00e1veru sme sa vrhli na o\u017eivovanie sl\u00e1vnej Gamy’88, ktor\u00e1 je v Ub880d-ho zbierke. Nevymysleli sme ni\u010d nov\u00e9. Jej sympt\u00f3my s\u00fa st\u00e1le rovnak\u00e9. S PROM z Amstradu (+3) funguje spo\u013eahlivo. S EPROM sa rozbehne, ale iba bez pripojen\u00fdch perif\u00e9ri\u00ed – konkr\u00e9tne divIDE. Tie\u017e sme zistili, \u017ee v osadenej EPROM nebolo na adrese 0000h DI, ale NOP. To by tie\u017e mnoh\u00e9 vysvet\u013eovalo – hlavne t\u00fa nestabilitu po zapnut\u00ed. M\u00f4j predpoklad je, \u017ee s mierne nestabiln\u00fdm origin\u00e1lnym zdrojom, ktor\u00fd pod\u013ea m\u0148a zakmit\u00e1va, sa na v\u00fdvod 1 – Vpp dostane impulz, ktor\u00fd EPROM preklop\u00ed do programovacieho re\u017eimu. Je jasn\u00e9, \u017ee jednotliv\u00e9 bity sa daj\u00fa programova\u0165 iba na nuly (preto maj\u00fa v\u0161etky bunky po zmazan\u00ed hodnotu FFh) a nie\u010do v po\u010d\u00edta\u010di jednoducho na zbernicu t\u00fato hodnotu pretla\u010d\u00ed v momente ke\u010f je Vpp EPROM akt\u00edvne.<\/p>\n

<\/p>\n

Hladom sme ani tentokr\u00e1t netrpeli. Ffg sponzorsky prispel plechom franc\u00fazskych zemiakov. Vraj mal nachystan\u00e9 2, ale to by u\u017e pre troch bolo viac ako by sme dok\u00e1zali zjes\u0165.<\/p>\n

<\/p>\n

\u010cas letel ako bl\u00e1zniv\u00fd. Ke\u010f sme sa zrazu spam\u00e4tali bolo \u010dosi po \u0161iestej ve\u010der. Zbalili sme to neskuto\u010dn\u00e9 mno\u017estvo techniky a s dobr\u00fdm pocitom sa odobrali domov.<\/p>\n
