Ahoj,<\/p>\n
jmenuji se Libor Lasota a s p\u0159est\u00e1vkami v\u00edce \u010di m\u00e9n\u011b dlouh\u00fdmi se st\u00e1le vrac\u00edm k mikropo\u010d\u00edta\u010di, na\u00a0kter\u00e9m jsem kdysi za\u010d\u00ednal. K PMD-85, p\u0159esn\u011bji k jeho verzi 2A, kterou pova\u017euji za nejlep\u0161\u00ed. Pro\u010d? Asi proto, \u017ee tuto verzi m\u00e1m doma. J\u00e1 je m\u00e1m tedy doma v\u0161echny, jedni\u010dku, dvojku, dv\u011b \u00e1\u010dko i trojku. Ale verzi 2A m\u00e1m podv\u011bdom\u011b nejrad\u011bji. Pr\u00fd je\u0161t\u011b existovaly verze 2B a 3B, ale ty jsem v \u017eivot\u011b nevid\u011bl a z\u0159ejm\u011b se jednalo jen o m\u00edrn\u00e9 modifikace.<\/p>\n
P\u0159ed dv\u011bmi lety jsem si postavil klon PMD-85. M\u011bl p\u0159ipojen\u00ed na VGA monitor, PS\/2 kl\u00e1vesnici, 128k RAM, z toho ca 56kB dostupn\u00e9 v kuse od adresy 0 a podporu pro pam\u011b\u0165ovou SD kartu. Nazval jsem jej Ultralight 80C85, proto\u017ee jej tvo\u0159ilo jen p\u00e1r \u010dip\u016f: 80C85 taktovan\u00fd na 3,072MHz, hradlov\u00e9 pole, RAM 128kB, ROM 128kB, RAMDAC\u00a0a\u00a0UART 88C681. Velikou oklikou jsem se b\u011bhem dvou let a dal\u0161\u00edch verz\u00ed tohoto jednodeskov\u00e9ho mikropo\u010d\u00edta\u010de dopracoval k tomu, \u017ee dal\u0161\u00ed verze bude (op\u011bt) pravd\u011bpodobn\u011b kompatibiln\u00ed\u00a0s PMD-85 na \u00farovni strojov\u00e9ho k\u00f3du, obsazen\u00ed pam\u011bti a organizace VIDEORAM.<\/p>\n
A ne\u017e jej zase navrhnu, osad\u00edm a vylep\u0161\u00edm BIOS (po kolik\u00e1t\u00e9 asi?), tak si ud\u011bl\u00e1m meziobdob\u00ed, kdy se vrhnu na programy pro PMD-85 a ty pak jednodu\u0161e p\u0159eportuju na sv\u016fj nov\u00fd Ultralight IV. Mo\u017en\u00e1, \u017ee to nebude Ultralight IV, mo\u017en\u00e1 to bude replika PMD-85, z\u0159ejm\u011b ji\u017e zm\u00edn\u011bn\u00e9 verze 2A. Dopln\u011bn\u00e1 o syst\u00e9m COLORACE, zvukov\u00fd \u010dip, podporu SD karty a.. na n\u011bco u\u017e se p\u0159ijde.<\/p>\n
Na t\u011bchto str\u00e1nk\u00e1ch bych cht\u011bl prezentovat bu\u010f m\u00e9 vlastn\u00ed programy pro PMD-85 nebo p\u0159eportovan\u00e9 z jin\u00fdch syst\u00e9m\u016f. J\u00e1 osobn\u011b pou\u017e\u00edv\u00e1m simul\u00e1tor PMD-85 pro Windows od skupiny RM-Team (viz sekce „Download“), pro kter\u00fd budou ur\u010deny i v\u00fdsledn\u00e9 zkompilovan\u00e9 soubory. Budu se ale sna\u017eit uv\u00e1d\u011bt i \u010distou bin\u00e1rn\u00ed podobu pro ty, kte\u0159\u00ed by to cht\u011bli pou\u017e\u00edt pro svou dal\u0161\u00ed \u010dinnost<\/p>\n","protected":false},"excerpt":{"rendered":"
