What makes PCs complex is the standards creep, since most PC standards
were ignored or poorly implemented things that should work often didn't
or did
only after a fashon.

For vaxen especally the Qbus models the ruls were very narrow and it was
enforced internal to DEC and Protocals like MSCP were patented if a third
party wanted to do it it's implementation was generally good.

Now the likely thing is you either did an ESD hit to something or while
pushing/pulling something you may have altered a switch, jumper or maybe
puped a chip loose.
