This is the group I worked with for DEC in Marlboro from 1981 to 1985. It's Cost Center 341 (CC 341), and included TOPS-10, TOPS-20, and Layered Products (where I was) as I remember it. I think these were the best group of people I've worked with so far.
I'm not actually sure these were even shot in 1984. Might have been 1983 or even 1985. No markings on the slide mounts or anything useful like that.
As you can tell, these were shot in direct sunlight, and the group was too big for me to be able to put up a diffuser, or even use a fill flash, to soften the light any. Then, the slides were 20 years old when I scanned them, which probably hasn't helped any. And my LS-2000 scanner doesn't really like dense slides all that much. Applied Science Fiction can only do so much.
One of the drawbacks of getting called on to shoot pictures like this is that I'm not in them.
Even the small versions of these are fairly large -- 1000 to 1200 pixels across. When you're trying to recognize people in a group this large, you need all the pixels you can get.
