Ok, let's see if I have technical knowledge needed to select the
camera.
1. I assume that an electronic shutter needs a battery.
2. A mechanical shutter does not need a battery.
My camera had a manual exp. mode, an auto exp. mode, and could also be
used without a battery.
1. Was there a such thing as an electro-mechanical shutter that could
also work in auto mode with a battery and still be a fully functioning
mechanical shutter without a battery?
2. If the answer to the above question is "No", then perhaps my model
was an electronic shutter with an X shutter setting ?
(in that case both the XR-2s and KR-10 would qualify).

Pentax ME Super, for one, defaults to the X-Sync speed of 1/125th without a
battery. Everything else works of course.

That's exactly what the "M90" setting did on my Nikon FEs.
BTW, I did own and use a Ricoh KR camera for a number
of years. I think it was the KR-5S or something like that.
Had a Pentax lens mount, if I recall. I chose it because it
was cheap and relatively light for an SLR, and carried it
with me over 700+ miles of the Appalachian Trail. A few
of my favorite pix were taken with that camera.

Pentax ES and its subsequent model, ES-II had fully mechanical shutters that
also operated electronically. The shutter speed dial had about 6 manual
shutter speeds--it was not a case where a lack of a working battery caused
the shutter to default to only one speed.
I am unaware of any other camera that used that particular shutter
arrangemement.

Pentax LX did 1/2000 down to X (1/50) upon battery failure.

Yes. That is the way auto cameras were made until the early 70's. The
current Nikon F3a works in this manner: a normally mechanical shutter
that can also be controlled electronically by solenoids.
Most early auto cameras with electronic shutters have a manual mode where
the shutter works without batteries but only at one speed.

Thanks,
As far as I can tell, none of the auto Ricoh XR or KR models had the
ability for multiple shutter speeds without a battery -- at least the
info on the web doesn't indicate a feature like that. The XR2 and KR10
do have single speed capability.
Thanks,everyone this has been educational and interesting.
