They are genarally described as "inactive ISA slots" however, when I see this (Frank uses his 2000's ISA slots for a NIC !!!) I'm again wondering : Can one make use of those "inactive ISA slots" to (actively) do things ?
"Inactive" means that they are not connected in any way to the Amiga. They just get power from the power supply and that's it. You need any kind of bridge board which connects one ISA slot to the Zorro slot next to it, then the bridge has access to all the ISA slots and to the Zorro slot, so with the correct software you can access the ISA slots from the Amiga side. But don't expect it to be fast.
