What if my keyboard connector does not fit into the keyboard port
on the VXIpc 800/700?
You can plug keyboards that have a 6-pin Mini DIN PS/2 type
connector directly into the VXIpc 800/700. You can use the keyboard
adapter cable that is included with every VXIpc 800/700 kit to adapt the
larger AT keyboard connector to the 6-pin Mini DIN connector.

Which interrupt levels are free to be used by ISA bus boards?
Which area of upper memory (adapter space) is free for use by ISA
bus boards or expanded memory manager software programs?
See Appendix B, VXIpc 800 Series System Resources, or Appendix C,

How do I install the VXIpc 800/700 in a slot other than Slot 0?
The VXIpc 800/700 automatically detects whether it is in Slot 0 of a
VXIbus mainframe. You do not need to change jumper settings to
install the VXIpc 800/700 in a slot other than Slot 0 unless you have
defeated the first slot detector (FSD) circuitry by changing the
appropriate jumper setting on the VXIpc 800/700.
Refer to either Chapter 3, VXIpc 800 Series Configuration and
Installation, or Chapter 4, VXIpc 700 Series Configuration and
Installation, for information on enabling and defeating the FSD
circuitry.
