Very cool way to revive a thread!
Although the photos say "AWADS #1", was that at the start of the mod, as I don't see anything AWADS about that cockpit, unless that year/version differed from what AWADS looked like in the 90's?
I passed through Little Rock in the winter of '92 to train in the C-130E and finished up in 2012 with about 4000 hours in the Herk, primarily the H-model. I don't recall too many sim specifics from '92, however they most-likely would have been the post-1982 digital versions you mention. They had rudimentary all-night visuals, IIRC. The training was excellent. One thing often forgotten about sims are their ability to replicate unique engine & system malfunctions. Although we often think of the "dial a disaster" where things pop up and the crew struggles to cope, the best training occurs when the IP says, "Let's look at the subtle difference between a throttle cable failure and a TD amp malfunction" and then sets it up so the students can relax, watch, and soak in the event without time pressure or distraction. The gauge indications, even the nuance of needle flicker, are essentially identical to the real thing. The effectiveness of sim training has more to do with the syllabus and IP/IF and less to do with the box itself. Unfortunately, we've seen the AF water down this program as it seeks to mirror the style of the airlines. We went from "building the airplane" in class years ago to "green line good, red line bad" today. Not even two-engine scenarios in the refresher sim.

As an airline guy, our training is also top notch, but the AF bosses seem to forget that when I have an engine issue in the Boeing, I give it to maintenance folks regardless of where I land. Given the same issue in a Herk, it may be me and the crew at a forward strip and if we don't either fix it or otherwise figure out how to work around it, we could be stuck in less-than-hospitable circumstances for an extended time; all that knowledge gained in the sim can come in handy on occasion!
Incidentally, the Herk sims, as of 2010, are vastly improved (specifically the C-130H2/3 at Dobbins in ATL). Color 24-hour visuals, terrain to fly low level, NVG compatibility, formation, airdrop, SKE, enemy threats, you name it. Very impressive but nowhere without the grandaddy device pictured above.
