Rumor has it that Bill Pechter may have mentioned these words:
So I was told at DEC Training. The PDP11/34 has the
SEX Multiplexer
doing the sign extend.
Seems hardware engineering had a little more leeway than the software
guys working on Macro11 and the assembler mnemonics.
Maybe at DEC, but not at Motorola -- in 6809 Assembly, there *is* a SEX -
which is Sign EXtend B register into A. (for working with the "D" register,
which is A&B put together.
Altho that's not the only (or even main) reason that's my favo[u]rite
CPU... :-)

Recycling is good, right??? Ok, so I'll recycle an old .sig.
If at first you don't succeed, nuclear warhead
