And Frank Hogg did his code with 21 bytes… the one I have, from Rainbow, is considerably longer. I wonder what it’s doing extra?

I need to find where I got that code from and see if it has assembly. Frank's looks very simple. Mask interrupts. Load byte from ROM, toggle to RAM, store, toggle to ROM, repeat.
