It's an M8192-YB. Not sure what that makes it. There is a 40-pin
socket on the board though, that I am given to understand is for
the accelerator.
All KDJ11 boards (as far as I've seen) have a socket for an FPJ11,
but bugs in the design prevented many of them from actually working
correctly.

The thought occurred to me that it might be nice to
have the
floating-point option in my PDP-11/73. Since I haven't got one,
and don't fancy paying the $500 or so that some online sellers
seem to be asking (do they really expect to sell *any*, never
mind at that price?), I was wondering how easy it would be to
implement in an FPGA as was discussed at length earlier in the week.
Feasible, or a complete waste of time?
Is your 11/73 a KDJ11-A or KDJ11-B? If the
former, it may not be
compatible with the floating point hardware anyway (M8192 without
a YA or YC suffix). Some early 15MHz KDJ11-B boards aren't either.
