Nope, the Cyber 70s were very minor upgrades to the 6000 series. A bunch of QSEs were made standard features, such as CMU (lower Cyber), CEJ, ILR, etc. Same cordwood modules, though. Blue-glass and fake wood skins, mostly. I witnessed a 6400 being upgraded to a Cyber 73; most of it was cosmetic. The 170s were quite different, however. --Chuck
