8-bit acorn software: other • Re: Updated Master MOS versions

Just curious. I put 350F as an extra model in b-em.
*ROMS now reports roms E and F being allocated by the MOS.
Why is this? And can these be switched out to put in other roms?
ROM F is part of the MOS and not available for use. The Master MOS is just much larger than the BBC B/B+ versions (it's pretty much 32 KB of code...), so it spills over into one of the sideways ROM banks.

Bank E is available for use, and should actually be empty in the prebuilt versions. If using one of the prebulit 128 KB ROM images I'd expect *ROMS to give you output along these lines for banks 9-F: (other banks may vary, as they are not part of the MOS)

(That image is taken from b2, but the output on real hardware is about the same.)

How have you set things up? I'm not very familiar with B-em but maybe I can try to reproduce this here.
