MEM 0040h:0040h - DISKETTE - MOTOR TURN-OFF TIMEOUT COUNT Size: BYTE Desc: number of clock ticks until diskette motor is turned off Note: the typical implementation of the timeout is to have the INT 08 handler decrement this byte on every clock tick, and force the diskette motor off if the result is equal to zero SeeAlso: MEM 0040h:003Eh,MEM 0040h:003Fh,MEM 0040h:0041h,INT 08"IRQ0"
