Micronik PCI A1200 Busboard

The PCI slots were to be used with an additional expansion that was never released. I imagine it would have been something like Elbox's Logic Card for the Mediator 4000.

The ISA slots aren't "active", meaning they only provide electricity, not a data path.
An old Commodore bridgeboard would let you use an ISA graphics card, but only on the PC side. Drivers exist to use some ISA peripherals, like ethernet and serial cards, on the Amiga side, but not graphics cards.
