Thanks to the flexibility that Quake console provided, we were able to set up a three computer null-modem cable network using an additional serial port card on one computer, and play Quake multiplayer like that. We’d felt like we’d hacked the planet at the time.
We did that too, except it was for playing OMF2097, because sharing a keyboard sucked (and we'd always fight over who'd get to use the right side of the keyboard, which was obviously the best side in those days).
