Yo dmc,
I think you're on the right track. Thanks.
The parts are all available just not at one place. Oscillator was harder to find as I think the mfr# is somewhat proprietary and I am only 98% it's the right part. But the Jameco spec's out with Mouser part.
I believe the ethernet connector and oscillator is in stock at Jameco.

I bet all of these parts can be substituted but they must spec out, but I am a noob. Perhaps the wiser folks will confirm this.
Passing this info on to anyone it may help.
