Welcome Nevin!
*I understand that a chap from the Nederlands has a socket that has been
modified to accept a silver oxide 1.5 volt battery and give as output 1.35
volts. *

I just ordered the BAT84 adapter from Frans de Gruijter. It should arrive
next week. I will report how it works.

*Eventually I should acquire a nice 3-cam 135 mm lens to use on my R-3 and
R-4 cameras. I enjoy using the cameras in Minolta XE series. Most of the
XE cameras have a maximum shutter speed of 1/1000 second. However, in
looking in my Minolta book that was published in Japanese on cameras and
gear for distribution in Japan I discovered that Minolta in 1976 released
the XE b model . In the Japanese special edition book they and gave the XE
b's maximum speed to be 1/2000 second. It is a very rare camera that seldom
comes up for sale these days.*
*
* It might be interesting to try your R3 in A mode and see if the actual
shutter speed goes beyond the indicated 1/1000. It works with Nikon FE,
where the camera reaches 1/4000 (1/1000 is max in manual mode). I must try
that with my R3 as well :-)
*When I was a college student back in the 1950's I took several courses in
chemical microscopy. In one course I took pictures through a microscope
using 4--inch by 5-inch sheet film without the use of a light meter. One
first had to take exposures on a test sheet exposing zones to different
amounts of light in a geometric progression. Then one went into the dark
room and processed the film to yield the correct exposure time. After which
one could take the photomicrograph. When one used an oil immersion lens,
one often had a long exposure time. In my chemistry of photography course I
received an orientation to the 4 by 5 Graflex camera. Its a shame the
processing of color 4 by 5 film has been discontinued. A 4 by 5 inch
digital sensor is just not feasible for the common folk.
*
*I just acquired a brand new-in-the-box Panasonic digital rangefinder - the
Lumix DMC-LX2 for $265 including shipping so I'll get to tinker with a
digital toy. I visited Wikipedia and typed in Lumix. The article had some
links that led me to an unofficial LX3 site which showed a Lumix LX3 coupled
to a microscope. So I might go unpack my microscope and get a Lumix LX3
camera that is about equivalent to the much more expensive Leica D-Lux 4 and
enjoy once again photomicrography. If I get good results, I might buy a
trinocular microscope with an excellent illumination system.*
That is great! A microscope is going to be my main tool (I´m a PhD student
in cell biology). Last year I took classes in SEM, TEM, Light, and confocal
microscopy. But I had to learn the basics on an old Zeiss research
microscope before professors allowed me to touch the million dollars
machines (Zeiss, Leica, Philips, Jeol,...) It`s funny (or not) to see the
prices for digital cameras dedicated to microscopes. These cameras (Nikon,
Oly, Leica or Zeiss) only have 1.5-5 mpx resolution but are more expensive
than a DMR or a M8!!!
There are many solutions how to adapt a compact digital camera (like your
Lumix) to fit a microscope here: http://www.truetex.com/micad.htm , and:
http://www.zarfenterprises.com/
The best solution is the newest Leica DM750 educational microscope with
integrated digital camera for around 3000 EUR:

I hope to see some of your Microphotographs soon.
Best regards,
Miha
