[Coco] Coco 3 with problems, can anyone help me troubleshoot?

[haywire666 at aol.com]

Mark is that something you can usually fix with the "repair service" I saw on your site?

It may be worth fixing for me but I think for the immediate future I'll just get a new coco from you...


I suppose I can ship the motherboard to you...

Might want to go read the CC3 service manual....Pg 44, SALT block diagram. 

My bet remains the same....blown SALT input on pin 11. Have seen this 
before.Yes, on a CoCo3.

The problem described here is on a CoCo 3... no SALT on the 3 :-(
