That's right.  I immediately started having second thoughts about the
index hole after posting that comment.  I never actually needed to
'notch' an IBM PC Diskette.  By the time I switched over to the PC from
TRS-80 and CP/M, 360K floppy drives were commodity and 'cheap' (I paid
$80 apiece for my first PC drives).
