Now that delays are OK for falcon, maybe you can keep 1.5 (I don't know 
what values / method are used by Atari's TOS to detect a drive is there 
or not)

I don't know if it's better ; TOS uses spin-up sequence, so maybe it's 
better to uses it too (especially if you later want to do a restore with 
verify=1, not doing the spin-up sequence could cause wrong result on a 
real hardware).

As for the spin-up / motor on flag, it's unclear in the schematic I have 
what is the behaviour when motor is ON for drive A: and you change to 
drive B: . As the FDC only knows one floppy drive, I would think that 
it's not aware drive select was changed in ff8802, so it would consider 
the spin-up sequence is already OK for drive B:
But I might be wrong, I don't have documentation or real measures to 
verify this.
