I'll give it a try.

I also put a virgin 170 chip in there, and programmed the latest MMBASIC into it in a vein attempt to see if that fixed it, but nope.

I really don't understand this one.    

EDIT: I've now put an LED bar-graph and resistors(1k) on all the pins, and wrote a very simple sequencer code to test each pin - 100% perfect.

I will make a very short video and post a link here later.
