Computer with sound card. Preamp to get the LP to line level audio.
Cable from preamp to audio in jack on computer's sound card. Some kind
of recording software on the PC. Audacity is Free / Open Source, and
runs under Linux and I believe Windows and Mac.
With this you can digitize the audio and save it as a .wav file(s).
You will then need some software to record these audio tracks on the CD
in CDDA (CD Digital Audio) format. On Windows, something like Nero
Burning ROM would do the trick, or maybe something from Sonic. Windows
Media player might also be capable of doing this. Under Linux try
Brasero or Gnomebaker. I'm not as familiar with CD authoring software
for the Mac, but I think there's a program called Alcohol 100 Proof, or
something like that.
I'm assuming you want to make a regular audio CD instead of burning a
data CD with a bunch of .MP3 encoded audio files, for example.

You'll need a sound digitizer program for the CoCo. Oblique Triad put
one out called Studio Works that may have ended up on some collection of
disk images floating around the Internet. You'll also need to make a
cable that connects your audio source to the CoCo's joystick port where
it will be sampled.
Another possibility, I think, is to use the 'play' program in OS-9 to
play audio files digitized on a modern PC. The CoCo's built-in hardware
will only do monophonic sound at 6 bits of resolution. If you have an
Orchestra 90 cartridge, it can play 8-bit samples in stereo. Of course
the sample size is limited by the memory of the CoCo. Not sure if
'play' can stream audio off a hard disk. Not sure Drivewire or floppy
disks could keep up with digitized audio. That's about all I know about it.
