<p>Stworzenie hasła</p> <p><b>Nowa strona</b></p><div>Płyta główna [[Mega ST]] to w zasadzie przeprojektowana do nowej obudowy płyta ST z następującymi dodatkami:<br /> * [[BLiTTER]]<br /> * Zegar czasu rzeczywistego RTC wraz ze złączem do baterii (2xAA)<br /> * Złącze rozszerzeń [[MegaBus]]<br /> * Złącze zewnętrznej klawiatury<br /> * Wewnętrzne złącze ACSI (zaraz za zewnętrznym złączem ACSI)<br /> <br /> === BLiTTER patch ===<br /> <br /> Prawdopodobnie wszystkie komputery Mega mają nalutowany na procesor tzw. BLiTTER patch zapobiegający zawieszaniu się systemu. Zawiera on układ SN74LS74AN (dwa przerzutniki typu D wyzwalane dodatnim zboczem).<br /> <br /> === Płyta główna Mega 1 ===<br /> [[Grafika:MB-Mega1.jpg]]<br /> <br /> Powyższy rysunek przedstawia płytę Mega 1 o numerze C103277 Rev. 2.2. <br /> * RAM w 8, 16 lub 32 kościach w zależności od wersji (Mega 1, 2 i 4) po 128KB<br /> * ROM w dwóch kościach EPROM (na płycie przygotowano miejsce na sześć kości jak w początkowych seriach ST)<br /> * Układ dźwiękowy Yamaha YM2149F<br /> * Układ I/O Motorola MC68901P<br /> * Sterownik FDD WD1772-PH<br /> * Dwa szeregowe sterowniki EF685OP dla klawiatury i MIDI<br /> * Shifter CO25914<br /> * GLUE CO25915<br /> * MMU CO25912<br /> * DMA CO25913<br /> * BLiTTER CO25913<br /> * RTC Ricoh RP5C15 zasilany dwiema bateriami AA (baterie znajdują się pod klapką w górnej części obudowy)</div>
