What happened to opcode C83 ---
C80 is MVCOS
C81 is ECTG
C82 CSST
C84 will be LPD
C85 will be LPDG
but where is C83 ?
the C8 rage looks like it is the collector for items that do not fit
anywhere else (at least I can not see any structure in there).

I checked the bit bucket already and it is in fact full of 0C3 ;-)

attributed to efforts to keep the X'46' from original

Yes, Abe mentioned that as a possibility. Do you know the op-code for MVCX?
Sorry. Don't know the opcode for MVCX. But, since I knew it was already
an assigned instruction mnemonic, I decided to use that name for a
macro. If they ever externalize it I'll be screwed. :-D
