OH. EM. GEE.

WOW! I'm blown away from that "Classic Notes" PDF!!
I do have a 35, a 45, a 55 and a 67 (and a 97) and there's SO MUCH KNOWLEDGE in that PDF file! WOW!
Thanks SO much for all the effort!!
It'll sure help a LOT in repairing my Classics!

(Now if only I had at least one single magnetic card to test the success of my repairing attempts ... ? There are currently some on ebay here in Germany – but is 2,40 Euros a "reasonable" price for one single card?? Any other sources? ?)

Okay, back to on-topic. Attached is a photo of a part of my 67's circuit board to which the card reader is connected – do I have to worry? Is this a serious problem? Should I repair this with small wires?
   

Oh, and I have other question regarding the card reader repair – is there a "best thread" to add them or should I start a new one?

Thanks so much, guys! Happy to have you experts here!! ?
