Hi Allison:

 Trust me they are not caps, the part someone described would come into 
 common use about 5-8 years later!  To tell if they are diodes an 
 ohmeter(VOM) and check for resistance one way and open circuit the other.
 No resistance in either direction is a cap! 
I spoke with a fellow who has a print set for the board, he indicated that
there are no diodes on the board at all. There are, however, quite a few
bypass caps shown on the schematic. My glass devices are all in parallel,
each associated to a particular, IC, and are grounded on the other lead.

I will have to remove an intact one to check resistance and determine what
they are.

Thanks for the reply,

Kevin
