> Na stronie: czy publiczność się nie irytuje że wątek drepta w miejscu? Poniekad jestes jak mucha rozsadku tlukaca sie o szybe niezrozumienia, ale jesli tylko masz czas - dokarmiaj. Publicznosci ostatnio brak igrzysk. ;) pozdrawiam, Vituniu PS: W temacie CAS i RAS: http://www.ianstedman.co.uk/downloads/A1200FuncSpec.txt ---[cytat]----------------------- The memory decoding takes the RAS and CAS timing signals provided by Alice and the multiplexed address bus and generates appropriate selection for 32-bit accesses. It also uses A1/A0 and SIZ1/SIZ0 on processor accesses to do the right decoding there. It supports 2-banks of 32 bit memory with 9-bit addressing for a total of 2M-bytes of chip memory. RAS selection is used for bank selection, CAS selection is used for byte write control and to avoid contention on bridged reads. Refrcsh is done with CAS before RAS and the logic must assert all RAS and CAS signals during refresh cycles.----------------[koniec cytatu]---Cos tam tez pewnie bedzie w stanie naswietlic dokument zatytuowany "Amiga Hardware Reference Manual"http://ada.evergreen.edu/~tc_nik/files/AmigaHardRefManual.pdf(ten traktuje akurat o A1000/500)
