Romanp, ISA connector on PC104+ Card?
You have all ISA-signals also in the PC104+ Interface, PC104+ is industrial "ISA-card" ...
If I don't understand you question properly, please follow up.

I don't use ISA in my design. The question is , if I should place ISA connector on my PC104+ card?

Yes, if you want to comply with the PC104+ standard your board must have the ISA (104pins) and the PCI (120pins) connectors.
It is for compatibility with legacy PC104 modules.
