Don't sweat it, it's only film capture data
The later film Nikons stored a few rolls worth of data but it's only for the metrics of the images, exposure settings and so forth (somewhat like EXIF in a digital image). Can be accessed and uploaded through the 10-pin connector of the F5, maybe the F100, don't know about the N90 but do remember hearing there's another camera connector besides 10 pin for one of the bodies. The PC cable mates up with an RS-232 serial port connector, or DB9 serial port via adapter. The Mac version might have used the ADC port. No recent computers are likely to have either port so it likely won't be plug and play on your laptop.
One interesting feature that the original PhotoSecretary software supposedly facilitated was to dial in a delay of X milliseconds on the camera, so that one could slightly lag and synchronize an F5 with an N90 daisy chained together, for simultaneous use of one set of strobes. There are also other user customizable functions on the F5, at least, which cannot be accessed any other way (i.e. not through the usual menu on the camera alone). There apparently was a cable and perhaps a little program for reprogramming the F5 from a Sharp Pocket Wizard, an older pocket secretary (a Palm-sized organizer) from the early to mid 90's. But then that device was eclipsed by the PC software version, Nikon PhotoSecretary.
The original Nikon PC software also allows for shooting (on film) while tethered to a computer and adjusting the camera settings remotely via a PC or Mac. Don't know about Hartalk and Softalk. Only recall they seemed to have no further tech support once they offered free D/L.
Please let us know what you find, I might need to lag my F5 sometime.
