At least if the RAM is attached to the 5200's Local Plus Bus in 16-bit
mode, no byte write accesses are allowed (byte /reads/ work, though).
I have a tweak (which I will post next week) to address this case,
which depends upon this setting. No idea if the same happens on other
chips and/or on 5200 in 32-bit (muxed) mode, but I guess similar
effects will pop up there, too.

Cheers, Albrecht.
