Believe it or not, most of the T-34s were pretty new. When I left in 2008, there were only about 4 "old school" hydraulic sims left and I think all of them had the computer screen/mouse controls. I never saw a sim w/out GPS/NACWS, which makes sense since the only non-NACWS aircraft were in the fleet and not at the TRACOM.
I've walked through the Whiting sim bays and they had a lot more of the gucci new T-34 sims with color operator consoles, and only a few of the older style with monochrome monitors. The older ones were all secured, probably because they're not needed. Plus those dedicated CPT trainers.
In TW4 we had 3 of the "newer" style sims with color monitors at the operator consoles and GPS/NACWS inside the cockpit. The other 4 or 5 were the older school style with monochrome operator consoles. Six pack was on the right, but NACWS was just a DME display. I forget if the GPS worked in the older ones. No dedicated CPTs, just the statics. The older motion sims were "finicky", to say the least.
