There were several "optional" system mods to the H17 controller and the
CPU card in addition to replacing the PAM ROM with XCON to allow org-0
booting - essentially setting up ROM shadowing for the lower 8k. If you
are presently booting a 64K (ie. org-0) system, you would need to
reverse the ROM de-select mods as well. I'll try to set up a 56K XCON
system and report back to you.
