Are those the MMC media format? MMC is exactly the same dimensions as
SD but is thinner and does not have a lock/unlock slider on it. MMC is
a locked format and not normally readable from a PC. You can put the
MMC cards in most or all SD card readers but when you try to see, read,
or copy the locked data from windows Explorer you will not be able.
And, since you can't see contents you can't copy it or back it up.

I think sometimes you can see one folder or file on the card and that is
used to run the locked data (normally a game or application) under a
given OS (like on the Palm MMC game/applications cards).

The home page from that site is a great place to get some specifics on
the different electronic chart formats and their applications:

I also wouldn't mind backing them up given their age. I assume such a
device exists but haven't been able to find anything that can read the
cards other than my current plotter.

The concept is that if you could back them up you could make copies and
give them away or sell them. And some people will do that, so those
that would not do it have to be punished too. It is all about money. :)
