 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.
