The MQ is standard on the PDP-8/E and up through the VT78 and the DECmates.
Not possible on the 8/L, but an easy option for the PDP-8/I and the PDP-12.
This could be a problem on the straight-8 [or LINC-8] with EAE though.
It's the only model where the SWP [MQA and MQL in the same instruction]
doesn't work [in case that matters].

Has anyone written PDP-8 code for .XOR. that uses the
MQ Register (when
the EAE isn't available)? If so, can you share the source code and/or the
algorithm?
Thanks,
