Tandem and Hard Hat, the Saga continues

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.
