Subject: Master 128: Hiding a routine from memory clear

Thanks for all the responses, guys.

I've been discussing it with Paul over on the RS forums, and I think
the general consensus from here and there is there's no easy way to do
what I originally had in my head.

The idea of clearing the &258 flag has it's own problem - after CE is
run the memory at &D00 is left full of junk which affects the way
sideways ROMs are handled on break (although Ctrl-Break works fine
because that will reset the ROM table).

>From what Paul has walked me through, I suppose I'm left looking for a
way to reset the master in such a way as to re-load the CMOS settings,
re-create the ROM table in &D00 but not clear the vectors.

I'll have a read up on the sideways RAM option, but might just have to
make the feature I had in mind BBC B/Electron only.

Cheers,

Peter.
