The resistors you mentioned were all about 990-995. Close enough.
I don't remember grounding the inputs when I tested it the first time. I will now add a 10K ohm resistor on all the inputs to ground.
(edit)
It's behaving very strangely. When I plugged it in, IN6 activated. All of the LED's on the board itself were lit, but IN6 fired. I went to post example and "turned the LED on". It turned off the IN2 (what pin 8 is hooked up to). Then I "turned the LED off and it fired IN2.
Oh, and the LED for IN1 no longer works. But I think I may have damaged it with a crowbar when I was trying to extract the nails holding it to my train table to bring it upstairs...

but all of the other ones are intact. (Another Edit: actually I just looked at it again and how I extracted it, and I didn't use the crowbar on that nail, I pulled it off by accident.. But the LED looks flatter than the other 7 working ones.. not sure how it broke though)
