Internal Hardwired MyIDE with 32-in-1?

[+Larry]

Is anyone using this combination? If so, can you make the MyIDE "transparent" if you wanted to attach a PBI device while the MyIDE is still in there? Install switch on one of the MyIDE leads?

 

Thanks,

Larry

Internal MyIDE uses the PBI IO ($D100) range. Thus when using a PBI device that also uses the PBI IO range, you need to disable the internal MyIDE. You can do this by adding a switch in the wire that runs between pin 14 of the 74LS138 chip and MyIDE. You probably also need to pull the now "floating" wire of MyIDE to +5V (I believe it is active low) via a pull-up resistor.
