Pred ned\u00e1vnom sme mali t\u00e9matick\u00fd SinDiKAT, venovali sme sa CP\/M. Ke\u010f\u017ee som tam mal Sama, pozrel som sa na to cel\u00e9 trochu bli\u017e\u0161ie.<\/p>\n

Implement\u00e1cia CP\/M pre Sam Coup\u00e9 je vo verzi\u00ed 2.2. Be\u017e\u00ed v grafickom m\u00f3de 3, 80 st\u013apcov a 24 riadkov, funguje aj na 256kB aj na 512kB verzi\u00ed po\u010d\u00edta\u010da. Sta\u010d\u00ed mu jedna disketov\u00e1 mechanika, zvy\u0161n\u00e1 voln\u00e1 pam\u00e4\u0165 sa pou\u017e\u00edva ako RAMDISK (124kB pri 256kB verzi\u00ed Sama, 380kB pri 512kB verzi\u00ed). Existuje aj verzia pracuj\u00faca s hardiskom, na t\u00fa sa ale mus\u00ed patchova\u0165 ROM a tak ju nepou\u017e\u00edvam.<\/p>\n

Form\u00e1t diskety je toto\u017en\u00fd s Amstrad PCW 8256. Je to 80 st\u00f4p, 9 sektorov na stopu, 512B sektor, dve strany, 720kB. Adres\u00e1r m\u00e1 d\u013a\u017eku 256 polo\u017eiek (RAMDISK len 128). Obrazy diskiet s\u00fa len \u010dist\u00e9 d\u00e1ta a tak je mo\u017en\u00e9 s nimi priamo pracova\u0165 pomocou dd pod linuxom, pr\u00edpadne SAMdisk pod Windows. Ke\u010f\u017ee nem\u00e1m pr\u00edstup k Windows, \u010falej budem popisova\u0165 len situ\u00e1ciu pod linuxom.<\/p>\n

Pre z\u00e1pis obrazu diskety je treba vytvori\u0165 nov\u00e9 zariadenie # mknod \/dev\/fd0u800 b 2 120, na z\u00e1pis potom sta\u010d\u00ed # dd if=name.dsk of=\/dev\/fd0u800 (toto je postup aj pre z\u00e1pis be\u017en\u00fdch diskiet pre Sam Coup\u00e9).<\/p>\n

Na kop\u00edrovanie s\u00faborov do a z virtu\u00e1lnych diskiet pou\u017e\u00edvam cpmtools (existuje port aj pre Windows). Po nain\u0161talovan\u00ed treba najprv upravit defin\u00edciu form\u00e1tu diskety. S\u00fabor diskdefs (u m\u0148a sa nach\u00e1dza v \/usr\/local\/share\/diskdefs) obsahuje defin\u00edcie diskov\u00fdch form\u00e1tov, tak\u017ee tam dopln\u00edme ten n\u00e1\u0161:<\/p>\n

end<\/p>\n

Ke\u010f m\u00e1me defin\u00edciu diskety, m\u00f4\u017eeme si nejak\u00fa vytvori\u0165. Pr\u00edkazom dd if=\/dev\/zero of=skusobny.dsk count=1440 si vytvor\u00edme pr\u00e1zdny s\u00fabor. \u010ealej pomocou mkfs.cpm -f pro-dos skusobny.dsk vytvor\u00edme s\u00faborov\u00fd syst\u00e9m . Nakoniec sta\u010d\u00ed cpmcp -f pro-dos skusobny.dsk GIF.COM test.gif 0: na nakop\u00edrovanie s\u00faborov (v tomto pr\u00edpade testovac\u00ed program na zobrazovanie GIFov, aj ke\u010f CP\/M 2.2 nepodporuje grafiku, tak\u017ee je tento program Sam Coup\u00e9 only). Kop\u00edrovanie s\u00faborov funguje aj v opa\u010dnom smere. CPMtools toho vedia o k\u00fasok viac, cpmls vyp\u00ed\u0161e adres\u00e1r diskety, cpmrm ma\u017ee s\u00fabory a tak \u010falej.
