\u00daprava ZX +3 na +3e pre dva r\u00f4zne diskov\u00e9 interace = ZX Plus3e2<\/sup><\/p>\n

Na niektorom z minul\u00fdch stretnut\u00ed som na z00mov podnet prerobil moju +3 na +3e s podporou divIDE. V\u0161etko funguje spo\u013eahlivo a k absol\u00fatnej spokojnosti, ale nev\u00fdhodou je „blokovanie“ divIDE v plus trojke. Ke\u010f nie\u010do potrebujem otestova\u0165 napr. preroben\u00fa Issue 6A, mus\u00edm neust\u00e1le prehadzova\u0165 divIDE medzi dvomi spektrami.<\/p>\n

 <\/p>\n

Navy\u0161e PLUS3DOS m\u00e1 in\u00fd form\u00e1t disku ako \u0161tandardn\u00e1 FAT – ktor\u00fa podporuje FATware v mojom divIDE – tak\u017ee okrem pres\u00favania interface z jedn\u00e9ho kompu do druh\u00e9ho som musel zaka\u017ed\u00fdm vymiena\u0165 aj karty.<\/p>\n

 <\/p>\n

Pon\u00fakalo sa jednoduch\u00e9 rie\u0161enie – dok\u00fapi\u0165 \u010fal\u0161ie divIDE, ale to mi pri\u0161lo ako luxus, ke\u010f som objavil zapojenie od Peru Putnika s jedn\u00fdm obvodom \u0161tandardnej rady 74HCxx a priamym pripojen\u00edm p\u00e4tice CompactFlash karty (CF) na zbernicu ZX Spectra.<\/p>\n

 <\/p>\n

Babra\u0165 sa s titern\u00fdmi 50 v\u00fdvodmi CF p\u00e4tice je pomerne n\u00e1ro\u010dn\u00e9, napriek tomu, \u017ee nie s\u00fa vyu\u017eit\u00e9 v\u0161etky piny, ale iba 31.
\nPreto mi napadlo pou\u017ei\u0165 pomerne \u0161tandardn\u00fa vec – redukciu CF na IDE, ktor\u00e1 by vyrie\u0161ila tieto probl\u00e9my a zaletova\u0165 vodi\u010de id\u00face zo \u0161tandardn\u00e9ho IDE k\u00e1bla by mal zvl\u00e1dnu\u0165 ka\u017ed\u00fd zru\u010dnej\u0161\u00ed dom\u00e1ci kutil aj trafop\u00e1jkou.<\/p>\n

 <\/p>\n

Nebudem chodi\u0165 okolo hor\u00facej ka\u0161e a vybal\u00edm ak\u00fd je v tom h\u00e1\u010dik. \u0160tandardn\u00e9 redukcie maj\u00fa v\u00fdvod 36 (WE) pripojen\u00fd na Vcc a v\u00fdvod 9 (ATA SEL) na GND. Toto nie je vhodn\u00e1 kombin\u00e1cia na Putnikove zapojenie, preto\u017ee oba v\u00fdvody sa pou\u017e\u00edvaj\u00fa.
\nAby to spolu fungovalo, je potrebn\u00e9 p\u00f4vodn\u00e9 prepojenie preru\u0161i\u0165 a vytiahnu\u0165 tieto sign\u00e1ly na in\u00e9 piny IDE konektora. Ja som preru\u0161il ATD8 (pin 4 IDE) a ATD9 (pin 6 IDE) a priviedol som tam ATA SEL (9 CF) a WE (36 CF).<\/p>\n

 <\/p>\n

Po t\u00fdchto zmen\u00e1ch je u\u017e redukcia pou\u017eite\u013en\u00e1 v\u00fdhradne na ZX, ale to nie je na z\u00e1vadu pri dne\u0161nej cene 2$ za kus napr. na DealExtreme (sku.711).<\/p>\n

 <\/p>\n

Gary Lancaster m\u00e1 vo svojom arch\u00edve +3e ROMiek zahrnut\u00fa podporu pre pripojenie CF kariet pod\u013ea Putnika.<\/p>\n

 <\/p>\n

Nasledovn\u00fd krok sa zdal by\u0165 logick\u00fdm – nahrad\u00edm +3e divIDE EPROMky za PCF alternat\u00edvy (CompactFlash Pera Putnik), konkr\u00e9tne diven3eA+B.rom za pcfen3eA+B.rom. Ale na divIDE som si predt\u00fdm naform\u00e1toval aj nejak\u00e9 MMC a SD karty a ner\u00e1d by som sa obral o mo\u017enos\u0165 pre\u010d\u00edta\u0165 si ich obsah, preto\u017ee nov\u00fd interface tak\u00e9to nie\u010do ne\u010d\u00edta a je zameran\u00fd v\u00fdlu\u010dne na CompactFlash.
\nRozhodol som sa, \u017ee pou\u017eijem EPROMky s dvojn\u00e1sobnou kapacitou – 27C512 namiesto 27C256 – a prirob\u00edm si prep\u00edna\u010d na v\u00fdvod A15 (pin 1). Ten je na doske +3 pripojen\u00fd priamo na Vcc, preto je treba vyhn\u00fa\u0165 no\u017ei\u010dku \u010d.1 tak, aby tr\u010dala mimo p\u00e4tice a na tak\u00fato no\u017ei\u010dku „vo vzduchu“ pripoji\u0165 log.1 cez odpor 1k2 na Vcc a vyp\u00edna\u010d proti zemi.<\/p>\n

 <\/p>\n

Pripojil som k +3e naraz divIDE aj Putnik ZX CF s t\u00fdm, \u017ee som dal do ka\u017ed\u00e9ho in\u00fa pam\u00e4\u0165ov\u00fa kartu, aby som mal istotu, \u017ee sa to spr\u00e1va pod\u013ea o\u010dak\u00e1vania. A bolo to tak. Pri A15 na log.1 sa po resete zinicializovala CF karta v redukcii, pri log.0 (sp\u00edna\u010d spojen\u00fd) sa zinicializovalo divIDE s t\u00fdm \u010do bolo na neho pripojen\u00e9. Na tak\u00e9to usporiadanie sa netreba pozera\u0165 ako s\u00fa\u010dasn\u00fd beh oboch interface, sk\u00f4r mi \u0161lo o to, \u010di budem m\u00f4c\u0165 pr\u00edle\u017eitostne prev\u00e1dzkova\u0165 divIDE aj ke\u010f budem ma\u0165 natrvalo pripojen\u00e9 ZX CF.
\nNem\u00e1m presne na\u0161tudovan\u00e9, ak\u00e9 porty divIDE pou\u017e\u00edva a \u010di je mo\u017en\u00e9, \u017ee by sa tieto dva interface bili, pokia\u013e s\u00fa pripojen\u00e9 spolo\u010dne. Zatia\u013e to vyzer\u00e1, \u017ee nie.<\/p>\n

 <\/p>\n

Krokom, ktor\u00fd bude nasledova\u0165 je zabudovanie ZX CF priamo do +3. 3″ floppy je u\u017e d\u00e1vno vymenen\u00fd, za 3,5″, tak\u017ee je pod n\u00edm dostatok miesta na CF IDE redukciu. U\u017e len zohna\u0165 vhodn\u00fd plast ako predn\u00fd panel a vymyslie\u0165 mechanick\u00e9 uchytenie redukcie pod floppy.<\/p>\n

 <\/p>\n

Sn\u00e1\u010f to stihnem do najbli\u017e\u0161ieho stretnutia.<\/p>\n

 <\/p>\n

UPDATE (31.3.2010):<\/p>\n

Podarilo sa mi \u00fasp\u0161ene zabudova\u0165 CF \u010d\u00edta\u010dku pod floppy mechaniku ako som pl\u00e1noval. Ako nosn\u00e1 kon\u0161trukcia posl\u00fa\u017eila p\u00f4vodne z\u00e1slepka CD-ROM zo starej notebookovej docking stanice. Trochu pilovania, br\u00fasenia a v\u0155tania a 2 skrutky to \u00faspe\u0161ne vyrie\u0161ili o \u010dom sved\u010dia aj obr\u00e1zky. Tak som to nakoniec do stretka sithol \ud83d\ude42<\/p>\n
