OK, so I did find the 8271 install instructions and everything is installed as it should, jumpers included, though I did find this:

Pretty sure it's always been like that.
However fixing that that didn't resolve it and it still doesn't work, neither did a sousing with Electrolube, so I think I have to hit the pause button until the 1770 controller kit arrives and I can do a fresh install on the number 2 Beeb and see what's what.
