Re: Apple ][ plus 13 sector! Problems...

Bill Gerber,

    It is what I understand that there are two different sequencer logic
PROMs.  First is to use 9 bits that it can only have one zero while second
is to use 10 bits that it can only have two zeros.  It is why 13 sectors use
9 bits while 16 sectors uses 10 bits.
    Do you have 13 sector PROM that you can spare?
