Success. I now have an almost fully functioning machine. The only exception is no bluetooth. Bluetooth suggestions are welcome. I installed a Sonnet Presto Gigabit PCIe Basic ethernet card this morning and now have internet capability and access to my network printer. I tried a new airport card with out luck. The Sonnet Allegro USB PCIe USB 2.0 adapter card works for my keyboard and external USB hard drives. The firewire ports work.
