[Coco] So, my CoCo 3 may be having some trouble

Fri Aug 16 20:00:00 EDT 2013

Chris,
I think looking down from the top of the cart with the card edge facing you, you tape around both sides of the leftmost contact. I think that's right, especialy after seeing the pinout you posted. I'm pretty sure that's how my Orch90 is still taped (in storage, new one has no tape)

I thought that may have been the question.  I'm not opposed to dumping the ROM 
out.  Sounds like a simple enough process, though I've never tried it before.  
Pin 8 maybe?

Though... that doesn't actually say which pin 8 is. :)
