     I've got this friend who needs to do floating-point math (preferably
IEEE standard, but he'll take what he can get) on a 6809.  He wants to use
a M6839, which is a ROM with floating-point subroutines.
     He talked to Motorola here in town, and they told him they don't make
that part any more.  (He wasn't surprised.)  I believe he saw the assembly
listing of the ROM, which was a good inch or two thick.  (i.e., not worth
typing in.  Besides, that's probably illegal.)  Motorola tried to be helpful,
suggesting a few local places that might have the part left from days gone by,
but the ones who had heard of it didn't have it.
     So, does anyone know where we can get a 6839?  Failing that, does anyone
have machine-readable source to floating-point routines for the 6809?  Free
would be preferred, but they might be willing to pay if the price is right.
     Reply via email; I don't normally read this group.
