Not that I am aware of... I thought that apart from external
interfaces of various forms (including sideways RAM and so on), the
principle hardware difference of the Electron from the Beeb was that
it didn't have the Mullard teletext chip & so couldn't do Mode 7 -
which sadly was a very popular screen mode, as it took very little
RAM, something the Model B was notoriously short of.

I suspect you'll know this, but which 1980s
(8 bit) microcomptuer had
4-bit wide RAM at the hardware level? (The hardware did 2 memory cycles
to make up an 8 bit byte ot give to the processor).
Acorn Electron?
