Here's a terrible camera photo of my setup for that rip:

I'm using the µChameleon to capture the digital data:

There are some limitations:
- The firmware for doing this sort of streaming is still in beta.
- The streaming mode is very sensitive to the USB interface used. I only got it working reliably on one PC, and then only with a buffering USB hub attached (which I bought for the purpose on SPS's recommendation). They're working on this, but it's not certain that the problem will be solved.
- I can only capture 16 bits of data at a time, triggered by a separate line (rising edge, falling edge or - in this case - both). There are 2 more lines going to the demuxer that would be nice to capture since they indicate which time slot is being output at any time. However, in most cases it's easy to determine this from the data going to the DAC.
Positives:
- I didn't find anything cheaper to get the job done without requiring more electronics skills or time than I had.
- Starting Point Systems' email support is truly excellent.
I've now switched to capturing from my CM-32L instead of the MT-32, giving a full 16-bit resolution.
Thanks to Lord Nightmare for advice and keeping me motivated.
