Whats a ROM card?

["Matthew S. Carpenter" <msc1983@mac.com>]

Hello,

    I was going through all the things I got with My IIGS, and I opened up
this one box, and found a card and what looks like a bunch of chips that I
guess you're supposed to interchange on the card.  The card is labeled as a
"ROM CARD", it was made by Apple Computer.  I'd say its quite a bit older
than the IIGS though, it has a copyright date of 1978.

Here are some pictures.

The card and everything ells that was in the box:

Zoom in on lower left hand corner of the card:

I'm just wondering what this card might have been used for.
