     In that case, I'd buy a Brother labelmaker and label the things.
Nothing else would make any sense.  At that point, it wouldn't matter
what they were called as long as the name didn't change.

     I do telephone system installations as well, so I wouldn't have
any problem with it; but, it would be a rediculous thing to do

     The former is what I would call the "billing systems".  The
latter is just data transfer with possibly a bit of data transfer.
That probably didn't require a lot of horsepower.  The primary
criteria there was most likely that it didn't lose any data.
