Hi there,
I have a floating point processor (FPP) on a currently unused 11/23 CPU M8186 card (KDF-11A). From the manual, looks like this is a KEF11-A.
Also, in my working 11/23+ with KDF-11BA, I have no FPP. Makes it hard to use Fortran-77. The KDF-11BA manual refers to a KEF-11AA FPP.
Does anyone know if the FPP unit is compatible from the 11/23 to the 11/23+ - i.e., can I transplant the FPP chip from the 11/23 to the 11/23+ CPU card? Could it be that simple?
Please be gentle if this is a stupid question. I've used my best Google-fu and RTFMing to find the answer (and learned some new things about these cards in the process).
Thanks!
