- intention was to rip all this out and convert it to
a full I/O serial terminal, using an Arduino-based setup
that Lawrence Wilkinson has already built and tested:

Looks very nice! Is there documentation for it somewhere? I also have a Selectric
(unfortunately it's located distant from me at the moment so I can't provide
particulars) that I worked on interfacing to a micro in the mid-70's. I was using a
MC6800 in my recollection, but I don't believe that I ever achieved operational
status. Presumably I was working from an article in one of the hobbyist magazines of the
era. I would have guessed Byte, but that doesn't seem to be the case based on recent
search. Any hints from folks on what magazine/article that might have been?
The Selectric wasn't one of the curvy(ier) office models; I recall it being a rather
boxy affair with plenty of right-angles on the housing and a medium shade of blue --
presumably "IBM Blue". Rather utilitarian in design. Even *more* utilitarian
than this one:

It included a full keyboard. I'm not sure anymore whether it operated in local-mode
or was set up as two separate devices and therefore needed to be connected up to a remote
controller to get local copy. It might have been a rehoused Selectric mechanism in a
third-party enclosure and the IBM-like color a red herring. My recollection is that it
was longer front-to-back; presumably the rearward extension housed the additional
electronics. I have absolutely no idea how I acquired it. No luck finding a matching
photo online as yet.
I believe that the Selectric came configured for remote operation, but presumably using an
EBCDIC-based data stream. I vaguely recall a DB-50 connector, but it's been an
awfully long time ...
Does this description sound familiar to anyone?
