It boots and runs!!!!
I've spent most of today installing (through trial and error) Hard
Hat on the the Tandem. And It looks like I have been successful!
Check it out:

The installation process certainly wasn't what I would call smooth,
but it was worth it.
Thanks to everyone who provided me hints on identifying this
machine. I have never had access to an Indy/Indigo/Challenge S before,
so identifying this machine on my own would have been a total guess
without the resources of this list and its archive.
Now the fun begins.
Thanks again.
