Each buffer is a one-sector buffer.
When a 2 kbyte-chip RAM is used, the maximum sector length is 512
bytes.
Bach buffer perform data transmission using the time-division mode.
b. Transmission speed for host computer and buffer
When transmitting data between the host and the 5-inch flexible disk
drive, the data is temporarily stored in the buffer register to enable
a freely selectable transmission speed. However, the sector interleave
is determined by the transmission speed between the host and buffer.
(For multisector mode)
