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. Brian H.

I don't have a reference handy, but there was a public domain floating point library written in C published in The Rainbow, I think last year, for OS-9 systems. If you can find that one, it should be fairly portable.
