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 = "Addition and Subtraction 1 --- TI-99/4A-Pedia{,} ",
   year = "2018",
   url = "\url{https://4apedia.com/index.php?title=Addition_and_Subtraction_1&oldid=621}",
   note = "[Online; accessed 27-February-2026]"
 }
