MVS 2slot board Capacitors?

I have a 2slot that has a missing a component. Its one of the little blue (I'm guessing its a capacitor) jobs that are all over the top of the 2 and 4 slot board and are marked with what looks like "104". If anyone knows what it is I would love to know so I could fix it. THANKS!

104 would indicate a 0.1 uF capacitor.

Probably a transient bypass capacitor, it filters noise at the 5 volts vcc supply to the ICs. The board would work OK even with the cap removed.
