I know the PCI interface isn't supported, so even if the VAX 7000 operated with the board installed there would be no drivers, so you'd have to write your own, which wouldn't be easy given the lack of documentation. Also, on your VAX 7000 you'll want to make sure you have the latest firmware installed. However, installing the latest firmware on the CPU boards can be a little dangerous if you aren't careful. For example, there's no failsafe, so if you mess up the CPU board would have to be replaced. Also, do you have any CIXCD boards in the system? If so, make sure they have the latest firmware. Otherwise, you are risking odd system crashes. -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/
