    Sorry, you are wrong.  Sixteen sector state machine ROM will not work
with the 13 sector code ROM.  Slate Machine for 16 sectors and 13 sectors
are very different because 16 sectors support two zero bits, but 13 sectors
support only one zero bits.
    I do have binary data for Slate Machine that can be burned into EPROM
chip.
    You claim that you bought 341-0009 and 341-0010 from eBay.  You are
probably mistaken that it is not truly 341-0009 and 341-0010.  It is true
that photo does show the label that prints 341-0009 and 341-0010.  The
seller does not have any 341-0009 and 341-0010.
    If you truly have 341-0009 and 341-0010, are you willing to sell them to
me?  I am sure that you say no.  What about 341-0004?  Do you have one that
is for Apple II's old monitor routines F8 ROM.
