I haven't posted any updates but that doesn't mean I haven't done any work on the sim!
The Nostromo speedpad is finally configured. It takes the toggle switche commonly found in light aircraft, elevator trim (on the wheel), and ignition switch simulated by the D-pad.
I scored a Saitek X36-X35T joystick throttle combination at goodwill for $6.
It works fine but it is the gameport version and I can't yet get full functionality through my Radioshack USB adapter.
I don't use the old yoke anymore as it sticks too much. I will post some pictures soon hopefully.
