Reports are that you can still get CP/M from Trisoft in Texas.

You'll most likely find it as part of a package with another member of
the family -- better hope so, because if they were separated, the
adapter card will have stayed with the CPU.

The only network card ever available was Arcnet, which only ran in Z-80
mode and was only compatible with other Model 2/12/16/6000 machines --
it won't talk to a network with PeeCees, even Tandy's ViaNet. And
there were some compatibility problems with the Arcnet version of
TRS-DOS.

Best bet there is to keep an eye on comp.sys.tandy and comp.os.os9
newsgroups. The MultiPak interface shows up now and again in the
thrift shops, RAM expansion for the Color Computer 1/2 is standard
chips, RAM expansion for the Color Computer 3 is generally found
inside a Color Computer 3 and can be hard to spot without some
disassembly required.
In fact, without OS-9 Level II, there is no way to detect memory
expansion in a Color Computer 3 easily -- well, I suppose there
might be a short machine-language program that could be poked in,
but I wouldn't know the details -- I drifted away from the Color
Computer line for a few years starting right about when the Color
Computer 3 was released, and I acquired OS-9 Level II before I
found my three expanded CoCo 3's at the Trenton Computer Festival
this past spring (and I still haven't had time to play with them
much).
What precisely do you mean by "Accelerator"? I've heard that there
is a way to replace the CoCo 3 CPU with a ?Hitachi? chip, but I
haven't been tracking the details. Somewhere around here I've got
a copy of some FAQ or other that might mention it. (There's a
good set of links for most of the TRS-80 line by Irs Goldklang at
