Try Chris Richardson's site 8bs, the address keeps changing, but
www.8bs.com, or http://8bs.jml.net should get you there.

Yes, there is/was a separate bbc-emulators mailing list, but it was
sort-of merged with this one some time ago.  I don't know if bbc-
emulators still has any traffic as I don't take it any more (someone
will no doubt jump in and tell us)

Um.  Would it be worth collaborating with the writer of one of the
existing BBC-micro emulators to adapt it for the Electron, as this could
save you a lot of work?  Off the top of my head, you'd have to chop out
the code for mode 7, the 6845 emulation, make major changes to the
keyboard handler, emulate the special features of the Electron's ULA (if
you could find docs for it), reduce the processing speed to about 10% of
that of the BBC...  I think my brain just blew a fuse.
