Telescience Computers in the Adventure Area entrances

[Zamujasa]

Actually if you're doing that you might as well visit the Tech Outpost on the mining Z-level and grab supplies there, since you can scan a copy of the teleporter components and computer board in the diner, without having to bust into the mechanics area. You'd just need to borrow some glass, wires, and metal from somewhere (and even that isn't terribly difficult to come across).

Plus, if you take along a beacon or manufacture a new one, you'll be able to teleport back and forth from the computer without issue.
