Just for completeness and for future searchers who may run across my original 
message, I *was* able to get the typewriter open and get it fixed. After 
removing the two screws near the platen that hold the top on, you just have to 
pry the top up really hard. It's held in by two large metal posts in very 
strong clips.

The fix for the typewriter was actually very easy, it was just a blown fuse. 
I've now got it working with the Messenger Module and I'm able to print to it 
with both RS232 and parallel connections. I've also documented what I've been 
able to find about the escape codes for formatting and the dip switch settings 
on my blog:

I'm disappointed that typing on the keyboard doesn't send anything out the 
RS232 port, but that was expected. But the typewriter works now and it's pretty 
cool watching it automatically type under computer control!
