I seem to remember (these days that's as good as it gets... ) shooting it in college, about 35 years ago. I may be wrong, but I recall shooting it at an EI of around 6-12, and developing it for continuous tone. I don't remember the developer, but do recall (if I'm correct) getting Tech-Pan-like results. Then again, I may be remembering something else...
It is completely the opposite. More like an early "super speed" film, like what would be T-Max 3200 today.
