Minul\u00fa sobotu sme sa stretli po prv\u00fd kr\u00e1t od za\u010diatku na\u0161ej p\u00f4sobnosti.<\/p>\n
Hne\u010f na \u00favodnom stretnut\u00ed sme boli v silnej zostave: Nairam, \u010ci\u017eo, z00m, ub, ja (ikon) a dve moje ratolesti – Katka a Soni\u010dka – \u013eudovo naz\u00fdvan\u00e9 ikonky.<\/p>\n
<\/p>\n
Po \u00favodnom obozn\u00e1men\u00ed sa s priestormi a vybalen\u00ed techniky sme sa vrhli na "na\u0161e" veci. Prv\u00fdm bodom bolo zabavi\u0165 deti, aby sa nenudili. Tak\u017ee na ZX +3 si zahrali svoje ob\u013e\u00faben\u00e9 Rainbow Island, Pacmaniu, Paperboy, RoboXonix. Na emul\u00e1tore fi\u010dali podobne diskov\u00e9 image z +3 a navy\u0161e Arkanoid, ktor\u00e9mu som nijako nevedel upravi\u0165 ovl\u00e1danie aby, v ZX Spine fungoval s kl\u00e1vesnicou.<\/p>\n
<\/p>\n
N\u00e1sledne z00m rozbalil svoj poklad V6Z80P. Po zbe\u017enom pribl\u00ed\u017een\u00ed architekt\u00fary a popise rozlo\u017eenia jednotliv\u00fdch s\u00fa\u010diastok na doske sme sa dostali k tomu \u010do to dok\u00e1\u017ee. Ke\u010f m\u00f4\u017eem hovori\u0165 za seba, t\u00e1to platforma ma uchv\u00e1tila. Demo s kr\u00e1snym plynul\u00fdm skrolom v 256 farb\u00e1ch, slu\u0161n\u00fd hudobn\u00fd podmaz k tomu a vraj Z80 nem\u00e1 \u010do robi\u0165, lebo o v\u0161etko sa postar\u00e1 FPGA. Pravdou je, \u017ee tento pr\u00edstup je vrcholne komodor\u00e1cky – od\u013eah\u010di\u0165 CPU kde sa d\u00e1 a narva\u0165 v\u0161ade nejak\u00fd koprocesor. Na druhej strane, ke\u010f to viem pekne oprogramova\u0165 cez zn\u00e1me in\u0161trukcie, tak ma to veru l\u00e1ka. <\/p>\n
<\/p>\n
ZX Emul\u00e1tor na V6Z80P, ktor\u00fd sme si pozreli ma ve\u013emi nepresved\u010dil. z00m spom\u00ednal, \u017ee nesed\u00ed \u010dasovanie a tie\u017e bol probl\u00e9m na\u010d\u00edta\u0165 nejak\u00e9 snapy. Ostatn\u00e9 veci, ktor\u00e9 sme si pozreli, boli zameran\u00e9 na fi\u010d\u00farie tejto architekt\u00fary – modplay, AY player, font selektor apod. Samotn\u00fd OS na V6Z80P nem\u00e1 e\u0161te \u00faplne v\u0161etky funkcie na 100% vyladen\u00e9, ale je to slu\u0161n\u00e1 a stabiln\u00e1 platforma. Jednozna\u010dne najlep\u0161\u00ed stroj so Z80, ktor\u00fd som v tre\u0165om tis\u00edcro\u010d\u00ed doteraz videl. <\/p>\n
<\/p>\n
Na mnou prinesenom C64, ktor\u00fd po skon\u010den\u00ed akcie pripadol \u010ci\u017eovi (kone\u010dne) sme testovali SD2IEC – podobne ako na Foreveri. Samotn\u00fd div\u00e1js funguje v poriadku, len C64 m\u00e1 nejak\u00e9 probl\u00e9my s farebn\u00fdmi atrib\u00fatmi. Sn\u00e1\u010f \u010doskoro n\u00e1jdeme sp\u00f4sob ako z\u00e1vadu odstr\u00e1ni\u0165. <\/p>\n
<\/p>\n
Nairam skenoval \u00e9ter a popri tom zistil, \u017ee moje vysiela\u010dky z DealExtreme vysielaj\u00fa na FRS-GMRS frekvenci\u00e1ch, kde je a\u017e 22 kan\u00e1lov. Zatia\u013e neviem, \u010di je to dobr\u00e9 alebo zl\u00e9, lebo netu\u0161\u00edm, \u010di je toto p\u00e1smo u n\u00e1s povolen\u00e9. <\/p>\n
<\/p>\n
Ke\u010f man\u017eelka pri\u0161la po deti, mohol som rozbali\u0165 HW a venova\u0165 sa \u00faprav\u00e1m dosky Issue 6A. Tento veter\u00e1n z m\u00f4jho \u00faplne prv\u00e9ho po\u010d\u00edta\u010da – Delty z Prioru – u\u017e pre\u0161iel mnoh\u00fdmi \u00fapravami. Ke\u010f sa jedn\u00e9ho d\u0148a pobrala do ve\u010dn\u00fdch lov\u00ed\u0161\u0165 ULA kvoli vypadnut\u00e9mu k\u013e\u00fa\u010du na Betadisku, za\u010dal som dosku vykuch\u00e1va\u0165 na s\u00fa\u010diastky. Postupne sa vytratili 4116, 4532, Z80, LM1889, 74LS00, cievka z meni\u010da… nakoniec zostala iba ROMka, ULA2 (Mullard), odpory a kond\u00edky. <\/p>\n
<\/p>\n
Ke\u010f som po dlhom \u010dase dosku opr\u00e1\u0161il, u\u013e\u00fatostilo sa mi jej z\u00fabo\u017een\u00e9ho stavu. Zvl\u00e1\u0161\u0165 dnes, ke\u010f je ka\u017ed\u00e9 Speccy vz\u00e1cnos\u0165ou som sa rozhodol, \u017ee ju oprav\u00edm. Funk\u010dn\u00fa ULU sa mi podarilo zohna\u0165 na ByteFeste 2009. Z80CPU som vyhrabal so \u0161ufl\u00edka. Teraz pri\u0161la na radu VRAM. Po\u010diato\u010dn\u00e1 snaha nahradi\u0165 8x VRAM za 1x SRAM sa nezdarlia. Pr\u00ed\u010dinu som zistil a\u017e doma, po skon\u010den\u00ed akcie. V mojom module som mal DIL HC574 a SMD 62256 vybrat\u00fa z dajak\u00e9ho m\u0155tveho HDD. Po zapnut\u00ed sa objavili na obrazovke \u0161tvor\u010deky a reset neprebehol korektne. \u010cudn\u00e9 bolo, \u017ee v \u013eavej polovici obrazu prevl\u00e1dala biela, v pravej zase \u010dierna. Premeral som v\u0161etky adresn\u00e9 aj datov\u00e9 vodi\u010de. Boli OK. Doma mi to nedalo, modul s SMD RAM som odpojil a osadil prec\u00edznu p\u00e4ticu na poz\u00edciu IC13 – 4116 \u00faplne na\u013eavo. Na nep\u00e1jiv\u00e9 po\u013ea som zapojil ke\u0161 RAM zo 486 a HC574 vyletovan\u00fa z p\u00f4vodn\u00e9ho ‚pr\u00eddavn\u00e9ho‘ modulu. V\u00fdsledok rovnak\u00fd – atrib\u00faty \u010diernobiele (v\u0161ak in\u00e9 som ani neo\u010dak\u00e1val, lebo namiesto LMka bola iba pr\u00e1zdna p\u00e4tica), ale reset nezbehol. Kone\u010dne som premeral aj RAS\/CAS a zistil som, \u017ee ULA PIN35 nie je spojen\u00e1 s ULA2 (Mullard) PIN1. Zrejme bol niekde od\u0161krabnut\u00fd kus spoja pri vyberan\u00ed obvodov z p\u00e4t\u00edc. Tie 2 piny som prepojil dr\u00f4tikom a v\u00fdsledok sa dostavil (c) 1982 Sinclair Research Ltd. <\/p>\n
Hniezdo som rozobral a pozap\u00e1jal pekn\u00fd nov\u00fd modul s rozmerom p\u00f4vodn\u00fdch VideoRAM. Fotku prid\u00e1m. <\/p>\n
<\/p>\n
Ub sa venoval zap\u00e1janiu memory mapy pod\u013ea n\u00e1vodu z konfery na nep\u00e1jiv\u00e9 pole a pod chv\u00ed\u013eou som ho vyru\u0161oval t\u00fdm, \u017ee som mu podstrkoval r\u00f4zne dosky popod nos – SMD PMD, Arduino, program\u00e1tor STK200. <\/p>\n
<\/p>\n
V\u010faka \u010ci\u017eovi sme po men\u0161\u00edch \u00fatrap\u00e1ch zohnali aj nie\u010do pod zub, aby sme od hladu nepomreli. Poobede sme to u\u017e v redukovanom po\u010dte 3 uzavreli, lebo s pln\u00fdm bruchom pizze sa robi\u0165 poriadne ned\u00e1. <\/p>\n
<\/p>\n
Pod\u013ea m\u0148a prv\u00e1 akcia dopadla nad mieru \u00faspe\u0161ne a u\u017e sa te\u0161\u00edm na pokra\u010dovanie. <\/p>\n
