I played your pack for a few hours now. And the energy-puzzle is nice. It took a while for me to recognize, that I do not want to dig for aluminium anymore - there must be another solution for HV-Wires ... and you provided one
About the Tunnel Bore of Railcraft. It is far more slow, than digging myself. And it is not able to place tracks on top of Fossil-Mod-Blocks (i.e. Permafrost-Block). It gets stuck.
About Open Computers ... I have no idea, where to find the instructions or . So, after having enough steam to power the computer, I have no obvious goal.
Nonetheless, I like the idea of this pack. And its mood. I am going to play it a little longer, maybe I missed a clue ;-)
The OpenComputer quest was removed on update 0.8.0, in favor of world seeds. It will be re-added in the next updated using custom floppy disks, but that may take some time... The tunnel bore is faster, even with the iron drill head, but not much faster, I may tweak block breaking once again. For new goals I recommend you to craft an Achievement book, it has some interesting tasks for you
Thanks for the feedback!
