UNIBUS <-> PCI bridge

(In case of ISA its death was good and should have happened far earlier then it did.) So if you design a PCI card today you may have trouble to find an old PeeCee with PCI slots tomorow. On the other side: Plain old PCI is a + as PCI cards can be used in e.g. UltraSPARC machines like a U10 or DEC Alphas. Have a look at e.g. http://www.opencores.org/ There are several PCI based projects. Maybe you can use an existing "FPGA on PCI(e) card" design. Probably you can by a readyly made PCI card. So all you need is a doughter card with proper UniBus / QBus transceivers. If you get the hardware done I will volunteer to write a NetBSD bus driver. (NetBSD does a very good job in abstracting device driver buss accesses. If I write a single PCI to UniBus / QBus bus bridge driver all UniBus / QBus device driver will just work with it. There is no modification of the device drivers needed.) -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
