Go ahead and take a look,
Psionicle players. Just remember that any of the feats listed in the tech package are pretty much off-limits for you, as you are all psionic or magical chars. The rest of the information there you'd probably be aware of (names of classes, an approximation of their abilities, etc).
GWolf - yes, it does mean that you could have a pistol at the start. Note that a pistol doesn't do much, and is considered a technological weapon (thus there is a chance that psionic/magic people/critters could not be affected by it).
However, for firearms, the d20 Firearm rules out on
www.sleepingimperium.rpghost.com are used. If you are interested in using a pistol, I can write it up for you - none of the tech weapons have been written up yet, save for the one that Jansson has.
As for the degree listing - I don't know. I'm not sure how much the guy I'm working with has done. I should have a reply within a week or two, though. As for weapon-making and explosives... they're all probably handled under the information in the tech packet, as normal devices. Damage will be determined based on real-world effects of the same stuff (if it exists in RL, which most of it probably will). Some of this information has been playtested, but it's pretty much still in development. Hopefully, there will be no major changes in how technology works IMC.
