Yes, but have you gotten any of them running yet? Trying to exercise computers
with no power connection is not too unlike necrophilia.

Well ... FUBAR was a common term in the military before there was an 11/780, or,
for that matter, a Digital Equipment Corp.

Not as far as I know.
FUBAR _is_ the official name for the failed unibus address register, as
used in the 11/780 user manual and printset, though.

What about on the 6809 (Sign eXtend) and the 1802 (SEt X).
Is it time to metion the ORL (Or Logical) and ANL (And Logical)
instructions on the 8048 series (and yes, they're generally pronounced as
you'd expect).

Yes, I am well aware of that. Point is, the acronym
(the usual expansion
of which you'd not use in polite company ;-)) was used for said register
in all the official manuals, etc.
I am quite sure the engineers at DEC knew what they were doing. I suspect
that the 'suits' didn't spot it until the manuals had already been shipped.
I think this one slipped through the corporate cracks.
One story I heard is that DEC engineers wanted to call the Sign Extension
instruction on the PDP11 'SEX'. They were stopped, and the mnemonic was
changed to SXT. Some other DEC engineers (probably), hearing this story,
decided to get their own back on the managment by calling this register
in the VAX FUBAR. This time it wasn't spotted before it was too late.
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.

I can't find the SEX Multiplexer on a quick glance through the printset,
but there is a signal called K8 SEX H from one of the microcode decode
PROMs to a multiplexer control input in the data path. Yes, it does sign
extension.

Rumor has it that Bill Pechter may have mentioned these words:

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... :-)
