This slip-up is during the scene when Crash Override is playing on Acid Burn's laptop in her bedroom during the party. You have to be a computer geek to recognize it, but then again these kids are supposed to be uber-hackers!
They are using an Apple/Macintosh Laptop but start talking about a P6 chip and PCI bus. The P6 chip is an Intel chip (we call it the Pentium 2), not Apple, and the PCI bus was not in Apple computers until much more recently. Just before this, the hackers (Nikon, Crash, and Goldstein) are ooh-ing and ahh-ing over it, and they mention that it has a twenty-eight point eight k-b-p-s modem!". No computer geeks talk like that. At most, someone would have said a "twenty-eight-eight modem" or "twenty-eight-eight-baud modem". Pedantic perhaps, but part of the culture.
These slip-ups wouldn't be so bad except this movie was supposed to show these super-computer users who end up being not so super. Perhaps a better on-site consultant could be used next time?
