I'm pretty sure all 8000 series boards will handle 4K editor roms.

Steve,
I did not look at the schematics yet ... do any earlier pet
      mainboards than the 8296 activate the /CS line for the all $Exxx
      and leave only out the I/O ports, like the 8296 does ? Otherwise
      they could only use 2K editor ROMs ($E000-$E8FF) without
      modification.
