The C> prompt on the computer leads me to believe that it is not an Apple II but a DOS based computer, either MS-DOS or PC-DOS. The TRS-80 was available in 1977 and the 8086 and 8088 were available in 1978/79. The 20826 came shortly thereafter.
Telecommuncations were available on these computers. The Internet was available in the seventies and eighties although it was only text, no graphics, and only for government, military, and education use.
