It's a random boards. PC boards without documentation -- or even with, if they implement some obscure or seldom-used function -- are generally worth less than cost of the components in them. You might see if your town has an electronics surplus store, and see what you could get for them there.

Does anyone know what this is and if it might be worth anything? I have a whole big box of them, packed in anti-static bags.
I suppose if no one wants them, I could always use 'em for shooting targets.
PLEASE PLEASE PLEASE let me know when you are going target practicing. My wife OKed my purchase of the AR-10 I had been looking at and I got it as my Valentines present. Always looking for anything to "plink" with it. Can you hook power up to the boards and get them to run away; nothing better than honing skills on a moving target.

Q often stands for quad pack, of something like transistors or FETs.
The S logo is Siliconix.
Looks like it's a quad, enhancement mode MOSFET.

Did you try to get in touch with Optotech???

Several things intrigue me. Here's a bigger better photo:
What's a VQ1006J by the way? I've been out of the field for awhile but don't recall those.

Yeah I just emailed them today, they'll probably reply this week.

targets.
It could be an early computer mouse.
Conceivably an interface board from some piece of kit presumably made by Optotech Inc.
Nothing of any real value there, although those optocouplers look of intruiging construction.

It is a control PCB from some ancient optical disk drive (from around
1987). If the drives were ever in production they must have been obsolete years ago so it will be worth nothing as a spare part and slightly more than nothing for the parts which could be salvaged from it.Optotech don't seem to be around anymore but were in Colorado Springs.

I'm pretty sure it's an SEP Field Generator.

If you have a really large quantity of PC boards, some of the parts are worthwhile (batteries, socketed ICs like the CPU and BIOS), and the
*GOLD* on them is well worth finding a recycler that handles such items. Find at least three, know how many pounds (maybe better yet board area) and get quotes. They will deduct costs of reclaimation but usually pay spot value (use Kitco for reference).
Sorry about my previous response; the reference was not available. I see no gold, and unless you needed some electrolytics, etc - the best bet is try some local electronic surplus dealers.
Sort of like 4 2N7000's.

Wow, you sure have a lot of cars in your front yard. I like the dog pictures also.

PS: Use the boards for target shooting.
Looks like an old motor controller board. The MC4044 is an old phase-frequency detector, and there are counters and an op amp, plus some things that are probably drivers (though I haven't looked them up). That would explain the odd-shaped cutout as well.
