Hi Christian,
Lay off the OLDE bit eh?

Few little things with JD.  GI had a missing string.  Pulled out the board and it turned out to ba a bad repair where the plated through hole was stripped out.  Fixed that with a jumper.  Had a few minor probs with trough optos, but that was only connectors. 

The only outstanding problem is the lamps.  At the moment when tested one at a time all the lamps in col 1-6 activate the bottom lamp in that same col, and 71 lights 81 as well, 72 lights 82 as well etc & vica versa.    Also lamps  78 and 88 are not working.  Getting there slowly.  I picked up the schematics and am working my way through the problems.  Tough to find the time right now.
Dave.
