Ah yes, those old radios were fun, weren't they.  At least back then, we 
could get our fat fingers inside them and work on things.  Today, the 
components are so small that even most sighted people can't work on 
anything.  Besides, half the functioning of modern radios depends on what's 
in the ROMs.
