Interesting. I wonder how it ended up in a box of ISA cards (and one
S-100 bussboard)? :)

Please forgive my ignorance (and the potential off-topic repurcussions),
but could this board's function be what it appears to be? (i.e. RAM) And
if so, what use is that in a telephone switch? And could the switch be
used to do any computing? ;)
