I'm not sure.  I thought of an unconventional use for one the other
day.  A friend had five 16M 30-pin SIMMs and knew that of four of them,
one was bad, but didn't know which one.

It occurred to me that putting them a 30-to-72 adapter could end up
getting them into a machine with more thorough memory-test
capabilities, and which byte lane errors appeared in would tell which
of the four was at fault.  (In principle, you could do as much with a
machine that took 30-pin RAM directly.  But if the memory-test
capabilities you have on such machines aren't up to what you have on a
72-pin machine....)

Yes, it's admittedly a rather recondite use. :-)
