As someone who is interested in all things regarding 80's and 90's computing, what was the early Internet like before GUIs? How similar/different was it from BBSs and Usenet? How did you access Internet pages before DNS and TCP/IP became de rigueur? Did JANET use T1 lines or ISDN? Did you have access to other online services/silos like GENIE, DECNET, or Tymnet?
