It is a cover that came with an old PCMCIA slot card for an old IBM laptop. The hucard sleaves fit but this protects better
I've seen those PCMCIA Cases for sale online, at several websites, for around three bucks each.
I haven't purchased anything from the sites I saw selling them, before, so I have to leave that recommendation up to someone else.
I wonder if Stone Age Gamer is planning on bundling one of those cases with his tricked out version of the TED.
If his Deluxe Edition fits in those cases, it would be ideal.
Actually, now that I think about it, if his DE fits in those cases, I can go ahead and just use it.
I was planning on getting one of his DE's and encasing it somehow, so I could have it on display in my game room.
