Hallo allemaal, Reading "User's manual for CBM5 1/4 inch Dual Floppy Disk Drives" (October 1980, P/N 320899, page 47), I read that such a drive has 16 buffers of which 3 are used by the machine itself. 16 buffers is equivalent to 4K, no problem here. The example for "memory-execute" (page 51) says "writes four bytes to buffer 2 ($1200 or decimal 4608)". Questions: - Regarding the above, the 4 KB of RAM is not in one row. Who knows the memory mapping of the RAM? (obviously NOT $0000 - $0FFF) - Which buffernumber is coupled to which memory area? - According my info the 1581 has 4 buffers. But it also has 8 KB of RAM. How many buffers has the 1581 indeed? - The memory mapping of these buffers? Many thanks. Groetjes, Ruud - This message was sent through the cbm-hackers mailing list.
