Thank you I'll definitely study this, as far as the Disk ii goes I've checked the solder joints and all look good Should I upload a video of my issues and if so what specifically?
I understand learning how to use an oscilloscope can be a learning curve. It is a beautiful tool to see more about how electronics behave. It shows you by the graph more information and illustration than a multimeter. I found the above guide that I thought could help you to get started.
Cheers!
