That's right and the zx6000 originally came factory shipped
with the mixed AGP+PCI-X cage backplane riser board.  It's
essentially of zero use to VMS, however, only if one intends
to run earlier versions of HP-UX, 'ancient' versions of Linux
IA-64 or any Windows for IA-64.

I had one of those riser boards in one of my rx2600's card
cages, thereby more or less turning it into a superficial
'zx6000'.  But as I was mostly interested in VMS, I removed
it rather quickly and sold it at some point.

I think I even managed to get that riser board to work in
an rx2620 with dual-core "Montecito" processors to some
degree, but it eventually caused problems (not all too
surprisingly, I guess, since it was wholly unsupported...
I think specifically due to the lack of support of certain
bridging logic, I think because later IA-64 architectures
lacked the hardware x86 emulation layer).
