From the project
Reverse Engineering of the 300zx (Z31) Digital Cluster & Design of replacement PCBs
Z31 digital clusters are one of, if not the best examples of this pure 1980s trend. Comprehensive instrumentation, large graphics, and gorgeous VFD illumination were a somewhat expensive option on the 300zx, as well as on Maxima, 240SX, Corvette, Celica/Supra, and a variety of other cars. As the cars languished in the transition period between "late model" and "classic", though, the digital package for the 300zx was not well liked.
