The official Apple adapter is not a cable but a large brick with
several cables coming off of it (inluding an AC power cable).
Unfortunately, I couldn't find any web pages with pictures.
I've seen it several years in a row at the Trenton Computer Festival's
flea market (http://www.tcf-nj.org/). The guy doesn't seem to be able
to find anyone who wants to buy it off of him :-) If you want to wait
until TCF-2004 (no dates announced on the web site yet) and travel to
NJ, there's a good chance that the guy will be there again, with a
shelf full of old Apple stuff, including the AUI adapter.

Don't know. You'd have to ask. I know that people on these
newsgroups have recommended SmallDog Electronics in the past, so it's
worth a try.
According to Apple:
<a rel="nofollow" style='text-decoration: none;' href="http://docs.info.apple.com/article.html?artnum=112279" target="_blank">http://docs.info.apple.com/article.html?artnum=112279</a>
a 6115CD has two 72-pin SIMM sockets. Memory must be installed in
matched pairs. Each SIMM should be fast page mode, 80ns or faster.
4, 8, 16 or 32M each. (For a total memory configuration of 16, 24,
40, or 72M).
According to MacTracker, the 6100 series can also accept 64M SIMMs
(for a total of 136M), but this is not an Apple-supported
configuration.
This memory is a generic type. Once upon a time, it was very
popular, but is now hard to find, since everybody is using variations
on SDRAM for memory.
Crucial.com (Micron's web store) only sells FPM in 32M sizes for $46
each. This is very expensive.
On pricewatch.com (a meta-index of small stores), 32M SIMMs go for
between $8 and $18 each. 64M SIMMs for between $16 and $39 each. If
you buy from a PriceWatch vendor, I recommend you research a vendor
before placing an order - not all of them are reputable.
Doing a Google search on the keywords "Macintosh", "6115CD" and
"memory" produced several hndred hits, many of which are stores that
will sell you the memory you need at a wide variety of prices. As
with PriceWatch, research any store you buy from - not everybody with
a web site is reputable.
People selling used SIMMs at flea markets and on eBay might also be a
good source. 32M SIMMs often go for $1 or less. (I remember one guy
at TCF two years ago who was selling random 72 pin SIMMs for $5 a
handfull.)

This Apple knowledgebase article may help:

It describes what you need to do to make this kind of cable. It says
that tbe biggest problem will be the 12VDC power supply, which AAUI
doesn't provide. You'll need an external power supply for that.
So I may have spoken a bit too soon - it probably won't be a lot of
engineering effort, but it won't be trivially simple either.
