Gordon.
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.
