The setting is spring break 1986 but they mention things like 'playing Nintendo' and such a few times. The NES was just launched at the end of 1985 in the US and was not immediately commercially successful. While a couple million units would be sold by the end of 1986 it was by no means buzzworthy by this point in early Spring of 1986.
In addition there is a plot point later on about a rumored secret 16-bit console which, even among super geeks, would not have been something people talked about in 1986. It wasn't until immediately before the launch of the SNES and Genesis that the notion of '8-bit vs 16-bit' became a real thing.
Then there's the UX on Suzie's computer which, though primitive, is far too windows-oriented for 1986. While Macs were indeed a thing by 1984 the adoption of that whole style was still in its infancy in the spring of '86. Its possible that a super geek like Suzie might have had access to Windows 1.0 (released in fall of '85) but anyone serious about computer use in 86 would have steered way-clear of Windows1.0 as it was painful to use and served no real purpose as it sucked up sooo many resources to do basically nothing.
Finally there's Suzie's use of IP addresses and TCP protocol which is just way too advanced for '86. Yes ARPANET existed at that point and NSFNET was coming online slowly, but those were highly specialized networks to which essentially no one would have access to in their homes. Is it possible that Suzie's dad is some professor / researcher or DOD contractor who works out of his house? Yeah, but its very unlikely.
Yeah yeah I know its just a show and I should really just relax, but these small things stood out to me as a nerd from the time period.
