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]. cjl On Wed, Dec 23, 2015 at 11:30 AM, Bob Vines <bobvine...@gmail.com> wrote: > Has anyone written PDP-8 code for .XOR. that uses the MQ Register (when > the EAE isn't available)?
