Hi Justin,

Great job on the ASR33!

In your first post, you said;
I finally have things to connect it to (primary hobby is retrocomputing).....I'm interested in other machines as well.  I have one retro machine that will speak Baudot, and it would be interesting to have something that will work with it. 

I am sure you know well that the ASR33 can be the console terminal for a home microcomputer such as SWTPC 6800 or Altair or a host of others. 

You could have your ASR33 and your Baudot machine interfaced via the microcomputer. I have done essentially this recently, although I was using my Mac512K, and later my Windows 7 laptop, as the MIKBUG console for my homebrew MC6800 based microcomputer. See demo videos at 

If you have a 6800/MIKBUG based computer  with a user parallel port via the MC6820 PIA chip, you could use my hardware interface design and software driver to effect this interconnection.
