Na ostatn\u00e9 stretnutie sme sa zozbierali v \u00factyhodnom po\u010dte.
<\/p>\n\n\n\n\n\n\n\n

Dostavili sa Ffg, Otis s Alanom, Morc, Martin Chabada, \u010ci\u017eo, Ub880d, Busy, Loki, Zden a ja. Chv\u00ed\u013eu sme pri k\u00e1vomate kecali aj s b\u00fdval\u00fdm Ataristom, ktor\u00fd aktu\u00e1lne rob\u00ed statika a zaujal ho plag\u00e1t SinDiKatu, vyvesen\u00fd na zasada\u010dke.<\/p>\n\n\n\n

Na on-line sa n\u00e1m na krat\u0161iu \u010di dlh\u0161iu dobu objavili Martin M1, Martin B\u00f3rik, Mirek Werner, Tornado a PedroS, no jednozna\u010dne najdlh\u0161ie vydr\u017eal Mikezt, ktor\u00fd sa popri in\u00fdch aktivit\u00e1ch venoval aj diagnostike Interface 1.<\/p>\n\n\n\n

Osobne som si dal za \u00falohu za\u010da\u0165 do v\u00e4\u010d\u0161\u00edch detailov sk\u00fama\u0165 zop\u00e1r \u201cle\u017eiakov\u201d. Konkr\u00e9tne som si priniesol Interface 1 so ZX PicoMD, ktor\u00e9 som postavil p\u00e1r rokov dozadu, ale dopodrobna zatia\u013e nepresk\u00famal. Sna\u017eil sa ohn\u00fa\u0165 zop\u00e1r tapiek z DISA na nahr\u00e1vanie z Interface 1, ako zvy\u010dajne som za\u010dal Manic Minerom. RAMTOP je tam v\u0161ak nastaven\u00fd tak n\u00edzko, \u017ee sa mi tam nezmest\u00ed Basic loader v IF1 syntaxi, v\u0161etky \u010d\u00edsla s\u00fa vo form\u00e1te VAL\u201d<da\u010do>\u201d a navy\u0161e treba prida\u0165 aj n\u00e1zvy s\u00faborov namiesto \u201c\u201d \u010do vy\u017eaduje \u010fal\u0161ie vo\u013en\u00e9 bajty v RAM. Rozhodol som sa nakoniec vyka\u0161\u013ea\u0165 sa na DISO ako zdroj vhodn\u00fd na prer\u00e1bky a rad\u0161ej sa \u010dasom pozrie\u0165 na na\u0161e star\u00e9 betadiskov\u00e9 prer\u00e1bky, ktor\u00e9 r\u00e1taj\u00fa s posunut\u00fdm za\u010diatkom Basicu o viac ako vy\u017eaduje IF1. Mohlo by to ods\u00fdpa\u0165 svi\u017enej\u0161ie. Uvid\u00edme.<\/p>\n\n\n\n

\u010eal\u0161ou aktivitou bol upgrade firmware na TheSpectrum, ktor\u00fd bol r\u00fdchly, bezprobl\u00e9mov\u00fd a v\u00fdsledok skuto\u010dne pote\u0161il. Dem\u00e1 typu Elkhaft2 alebo MDA, ktor\u00e9 intenz\u00edvne kade\u010do kreslia alebo p\u00ed\u0161u do borderu za\u010dali fungova\u0165 ako na be\u017enom ZX128, \u010do je naozaj pozit\u00edvne zlep\u0161enie oproti verzii, s ktorou bola t\u00e1to replika spektra dod\u00e1van\u00e1. V danej cenovej kateg\u00f3rii – pri cene pod 100\u20ac, za ktor\u00fa sa dal stroj zohna\u0165 koncom novembra, s ISIC z\u013eavou sa mi to podarilo stiahnu\u0165 na 90\u20ac – si dovol\u00edm poveda\u0165, \u017ee je to v s\u00fa\u010dasnosti asi najvernej\u0161ia replika \u010do sa t\u00fdka vzh\u013eadu, prevedenia a teraz u\u017e aj funkcionality, ktor\u00fa si m\u00f4\u017ee nad\u0161enec platformy zadov\u00e1\u017ei\u0165.<\/p>\n\n\n\n

Potom sme sa spolo\u010dne pustili do testovania dema Whole na dvoch in\u00fdch emul\u00e1toroch – STMZ800 a ESPectrum na TT-GO VGA. Oba sa spr\u00e1vali v podstate rovnako – po natiahnut\u00ed programu do pam\u00e4te zostala \u010dierna obrazovka a demo sa nespustilo. Na STMZ800 bolo po\u010du\u0165 zop\u00e1r t\u00f3nov z AY, ESPectrum v testovanej verzii \u017eia\u013e AY neemuluje. Ub880d dodal u\u017e rozbalen\u00fa verziu dema v snape a t\u00e1 na TT-GO VGA be\u017eala. S\u00edce sme nesk\u00fa\u0161ali ako dlho, ale zo spr\u00e1vania sme us\u00fadili, \u017ee to bude nie\u010do s inicializ\u00e1ciou \u00favodnej \u010dasti. A\u017e po stretnut\u00ed nakopli Busy aj Ub880d debugger a zistili, \u017ee demo intenz\u00edvne vy\u010d\u00edtava d\u00e1ta z AY a t\u00fato funkcionalitu ani jeden z emul\u00e1torov pravdepodobne bu\u010f vobec neemuluje, alebo to nerob\u00ed spr\u00e1vne.<\/p>\n\n\n\n

Alan s Otisom sa intenz\u00edvne pustili do testovania \u010d\u00ednskej pixel tabule s rozl\u00ed\u0161en\u00edm 32×32 bodov. Hoci v popise sa to tv\u00e1ri ako LED, v skuto\u010dnosti to sk\u00f4r vyzer\u00e1 na nejak\u00fd segmentovan\u00fd LCD. Chlapi po\u010das stretnutia hackli komunika\u010dn\u00fd protokol a za\u010dali do zariadenia posiela\u0165 u\u017e aj vlastn\u00e9 obrazce, ale najv\u00e4\u010d\u0161\u00ed \u00faspech mal animovan\u00fd Nyan Cat so spusten\u00fdm zvukov\u00fdm doprovodom z mobilu, lebo tabu\u013ea samozrejme repr\u00e1\u010dik nem\u00e1, aj ke\u010f komunikuje cez Bluetooth. P\u00f4vodne som toto zariadenie zahliadol tu\u0161\u00edm u\u017e minul\u00fd rok na Bytefeste niekde v okol\u00ed stola Michala Pol\u00e1ka, tento rok ho tam tu\u0161\u00edm mala na stole Aki. Mne tak nejako padlo do oka pri listovan\u00ed \u010dinskymi \u0161opmi, ale aj tak som ho na\u0161iel za lep\u0161iu cenu na Allegro. Neodolal som teda a k\u00fapil ho. No a po ostatnom stretnut\u00ed zapo\u017ei\u010dal mlad\u00e9mu hackerovi Alanovi, aby aj s pr\u00edpadnou podporou svojho otca doladil grafick\u00fd obrazec \u010di anim\u00e1ciu na nejak\u00fd pekn\u00fd mot\u00edv vhodn\u00fd na reprezent\u00e1ciu SinDiKatu. <\/p>\n\n\n\n

Ffg mal asi najdlh\u0161\u00ed zoznam vec\u00ed na opravu a presk\u00famanie, a\u017e sa mi zdalo, \u017ee je to nemo\u017en\u00e9 stihn\u00fa\u0165 za jedno stretnutie, ale ve\u013ea vec\u00ed sa rozl\u00fasknu\u0165 podarilo. Menujem z jeho p\u00f4vodn\u00e9ho zoznamu: PMI80Uno, STMZ800, WiFi smart kameru, sol\u00e1rne svietidlo, switch joy-cony a ne\u0161\u0165astn\u00fd kontrol\u00e9r na kolobe\u017eku, kde treba poh\u013eada\u0165 nap\u00e1janie riadiaceho ARMu.

Loki si na stretnutie nepriniesol ni\u010d na opravu, ale sk\u00f4r na archiv\u00e1ciu. Dnes boli na rade diskety 5,25″ DS DD. Pre neznal\u00fdch Double Sided, Double Density. Diskety boli pou\u017e\u00edvan\u00e9 pre po\u010d\u00edta\u010d Commodore 64. Jeho zbierka z mladistv\u00fdch \u010dias sa postupn\u00fdmi akviz\u00edciami rozr\u00e1stla o stovky \u010fal\u0161\u00edch diskiet a na tak\u00e9 mno\u017estvo si u\u017e teda treba pripravi\u0165 dobr\u00fd syst\u00e9m zhr\u00e1vania a kategorizovania. Na toto zhratie\/stiahnutie diskety je potrebn\u00fd u\u017e sofistikovanej\u0161\u00ed n\u00e1stroj ktor\u00fd to bude uklada\u0165 na nejak\u00e9 extern\u00e9 m\u00e9dium, napr. USB flash. Bol pou\u017eit\u00fd po\u010d\u00edta\u010d Ultimate 64, disketov\u00e1 mechanika Commodore 1571 a mali\u010dk\u00fd monitor Sony. Ultimate 64 je modern\u00e1 alternat\u00edva k po\u010d\u00edta\u010du Commodore 64, ale m\u00e1 u\u017e v sebe zabudovan\u00fd cartridge Ultimate 2+, ktor\u00fd m\u00e1 v sebe tieto funk\u010dnosti: Po prv\u00e9 je to utilita UltiCopy ktor\u00e1 priamo komunikuje s disketovou mechanikou, nahr\u00e1 do nej program ktor\u00fd ve\u013emi r\u00fdchlo posiela \u00fadaje. Tie s\u00fa zachyten\u00e9 a na obrazovke je zobrazen\u00e1 podrobn\u00e1 mapa pre\u010d\u00edtania sektorov diskety. Hviezdi\u010dka znamen\u00e1 dobr\u00fd sektor, poml\u010dka nepre\u010d\u00edtan\u00fd sektor. Po zhrat\u00ed diskety sa po\u010d\u00edta\u010d sp\u00fdta na meno s\u00faboru *.D64 a ulo\u017e\u00ed ho. M\u00f4\u017eeme pokra\u010dova\u0165 druhou stranou a potom \u010fal\u0161ou disketou.<\/p>\n\n\n\n

Je to ve\u013emi r\u00fdchle, av\u0161ak kombin\u00e1cia s mechanikou 1571 m\u00e1 svoje z\u00e1ludnosti. V\u017edy sa podarilo zhra\u0165 iba dve strany, potom musela by\u0165 mechanika re\u0161tartovan\u00e1 alebo resetnut\u00e1. Doma bol preveden\u00fd test s mechanikou Commodore 1541-II a t\u00e1 i\u0161la non-stop dobre. Druh\u00e1 funk\u010dnos\u0165 cartridgu je to \u017ee si vie vytvori\u0165 virtu\u00e1lnu mechaniku, kam sa namontuje pr\u00e1zdna disketa, prirad\u00ed sa mechanike in\u00e9 logick\u00e9 \u010d\u00edslo, povedzme 9. Potom be\u017en\u00fdm kop\u00edrovac\u00ed programom je mo\u017en\u00e9 kop\u00edrova\u0165 d\u00e1ta medzi fyzickou mechanikou (8) a virtu\u00e1lnou (9). Niektor\u00e9 diskety mali viac chybn\u00fdch sektorov pri zhrat\u00ed cez UltiCopy tak sme siahli aj po tomto rie\u0161en\u00ed. Mechanika bola vybaven\u00e1 roz\u0161\u00edren\u00edm RAMBoard 8KB. K nemu bol dod\u00e1van\u00fd aj kop\u00edrovac\u00ed n\u00e1stroj Dual41, ktor\u00fd by mal plne vyu\u017ei\u0165 tento buffer. S\u00edce to zhr\u00e1vanie bolo o tro\u0161ku pomal\u0161ie, odhad tak 20%, ale hl\u00e1silo to menej ch\u00fdb, niekedy dokonca aj \u017eiadne. Vyzeralo to tak \u017ee sa nepre\u010d\u00edtan\u00e9 sektory pok\u00fa\u0161a \u010d\u00edta\u0165 viackr\u00e1t. Neskor\u0161ia anal\u00fdza uk\u00e1\u017ee \u010do sa podarilo a nepodarilo zhra\u0165.<\/p>\n\n\n\n
