building a pci card
Hi,
The PCI bus specifiction requires appropriate electrical signals for interface logic. If you want to interface some chip to PCI bus you must use only PCI compliance chips!!!
One solution is to use commercial ASIC PCI bridge. Another is to implement PCI interface with PCI compliance programmable logic chip. For additional information about PCI interfaces look at PLD vendors site. (Some of PLD vendors are forbidden on this forum).
If you don't need high transfer data rate use serial or parallel port, ISA or USB bus.
