Just wondering
if anyone knows what these chips are for/from/etc.

Interesting look to them. I would say EPROM but the magnifying window
is weird...
Those look like "starburst" displays:

The window is indeed a magnifying lens. I ass-u-me that LED technology
was still a bit naff back in the 1970s and it was more practical to
optically enlarge the segments than make a chip with physically larger
segments. This compromise produced an odd visual effect, which is
likely why it's not done any more.
