8-bit acorn software: other • *CONFIGURE SHADOW

$

BeebWiki has a note about bit 0 of CMOS RAM byte 16, seemingly unused by the MOS: (https://beebwiki.mdfs.net/CMOS_configur ... allocation)

Code:

   16 b0     Default to shadow screen on start (MER)  *Config. Shadow
Anybody know what this refers to? I couldn't find anything obvious in TobyLobster's ROM library.

The Dabs Master Emulation ROM is for B/B+ only, so CMOS RAM allocation wouldn't apply.

Anything called "Merlin" looks irrelevant.

I wondered if there was a Master Enhancement ROM or MOS Enhancement ROM or something but "enhancement" only brought up the Beebug Master ROM. The manual suggests it doesn't add anything to *CONFIGURE.
