Differences between chk=86 and chk=0E versions are unknown. The chk=0Eh and chk=8Bh versions are almost byte-identical, they differ only by some bytes related to the new AMSDOS version used in CPC Plus system cartridge (aside from the new AMSDOS version, there is no support for CPC Plus related features, like handling the new ASIC registers).
