It has been a while since I've had time to write here.
My latest hacking has been in some end of life honing for the oldcard system. I've cleaned up many of the constants that were scattered through the source after finally finding the datasheets for most of the parts that were being so identified.
It also looks like it should be possible to share the managment and card interrupts. I'm looking into various possibilities here and will prototype them in the OLDCARD system. With this in place, I should be able to support the pci cards to a limited extent with OLDCARD.
