As I am too lazy to go and desolder any DB19's , which probably won't fit anyway..

The closest ones I can find which I have in stock ( https://www.exxosforum.co.uk/atari/store2/#0034 )

I pushed the connector towards the back a little to line up the holes better.. Then forced in a bolt to align it while soldering ( I am good at shoving large shafts into tight places)

Bodge fix #1 done 8-)

Any top tips for getting that cart port into the H4 with all the bent pins? I found it a major pain in the butt.
If it ain't broke, test it to Destruction.

I have the same problem with the DIP 68000's, hence moving to PLCC68 :lol:

Good point. I get fed up and solder female headers onto my tester DIP CPUs.
If it ain't broke, test it to Destruction.
