No need to e-mail (but should work here in the forum using the "contact" link).
As for the PCI cards: I've got several plugged in, but all of them are 3,3V types and work "out of the box", at least as far as the startup diagnostic goes. Drivers are another matter. I do have network running under MiNT (has been discussed here and/or on the atari-home.de forums), I've had a USB keyboard working for testing, and of course the graphics card at 1600x1200. A spare firewire card is stored in the fourth slot on the CTPCI. It's recognized at boot, but lacks drivers and I don't have peripherals to connect to.
