        VAX 7000/DEC 7000). 
 
The reason why I was asking is that I've seen a lot of sellers selling
boards that would work in both 7000 and 8400 boxen.
          If it works you will have the pleasure of
writing some
        VAX drivers for PCI. Don;t forget that some LSB modules
        had Alpha-only firmware: I presume they had carnal
        knowledge of Alpha MMG data structures which
        are different on VAX. So just because it does not
        smoke when you drop it in the slot does not
        mean it is useful! 
That's what I was getting at.  If I could get my VAX 7000 system running
with PCI cards, then I could do some *serious* expansion to my VAXcluster.
All has to do with the quantity of PCI cards currently being made.
  can find TXXX
XMI/BI, EXXX Laserbus, and other reference numbers 
 for
 boards? 
        For VAXBI, VAXft and XMI you can start here:

Yes, I've seen that one.
          There are various "field guides"
dotted around the
        net that cover Omnibus, Qbus and UNIBUS. 
I'll look for "field guides" and see what pops up.
          I've got a list somewhere of LSB and FBUS
        stuff. Is there anything specific you
        wanted? 
Actually, I just wanted to put name and function to all the part numbers I
am seeing floating around the 'net.
