Sorry for insisting, but too be very precise I have another wording/test :

On real HW, if you set timeout to 9 sec, disconnect drive A and wait for 
bit 5 of ffffa01 to go to 0 :

 - does bit 5 go to 0 before those 9 seconds ? And if so after how many 
seconds (approximatively) ?

 - does bit 5 always stays to 1, and the timeout expires after 9 
seconds, indicating the fdc was not able to complete the restore command ?

Basically, if you set the timeout to 1 minute and disconnected both 
drive on real HW, would it take 2x1 minutes for EmuTOS to consider the 
drives are not available ?
