BibTeX entry

 @misc{ wiki:xxx,
   author = "TI-99/4A-Pedia",
   title = "Sierra On-Line --- TI-99/4A-Pedia{,} ",
   year = "2018",

When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "TI-99/4A-Pedia",
   title = "Sierra On-Line --- TI-99/4A-Pedia{,} ",
   year = "2018",
   url = "\url{https://4apedia.com/index.php?title=Sierra_On-Line&oldid=2560}",
   note = "[Online; accessed 2-May-2026]"
 }
