Just checked though. The .bin download file we generate for the ALL-07 is 69k long: ie 0-10FFFh. 0-FFFFh is, of course, the APROM code, and 10000-10FFFh is the LDROM code. I assume the '58B .bin file you must generate must be 0-8FFFh: ie 0-7FFFh APROM and 8000-8FFFh LDROM. Our ALL-07 sorts it all out from that map.
