Bitsavers doesn't have a wealth of Interdata documentation, but there is some:

  http://bitsavers.org/pdf/interdata/32bit/

Someone who's familiar with the 360 instruction set should be able to look
at e.g.:

  http://bitsavers.org/pdf/interdata/32bit/8-32/8-32_Brochure_1977.pdf

and see how compatible it is.
