Is it a setup where early reads are forced to enable the ROM, but the code has to jump to the "real" ROM address? That was common on some other processors, but there's no obvious reason to do it on an ARM.

Also for some other good clean ROM dumps: https://archive.org/download/MagicCapROMs … Two of the Motorola Envoy ROMs are from pre-release hardware, HIX-300 is unreleased hardware and was Bill Atkinson’s personal unit. Just in case you or somebody you know likes DragonBall processors :)
