What is a Mark III Card Catcher?

[RetroReserve]

Hey everyone,

I've just bought a device called a Card Catcher for the Mark III. According to the seller it allows you to play card games on you Mark III but I was under the impression that there was already a card slot on the Mark III.

When I get it, probably some time next week, I'll post some pictures of it.

Anyone heard of these before or already have one?

Your right the Mark III does have a card slot. Its actually designed for the SG1000, SG1000-II and SC3000 machines which only have cartridge slots. It seems wierd now that they would release SG1000 games on cards when there wasnt a card slot as standard, but back in the 80's a game the size of a credit card was very impressive stuff.

My hopes of getting a prototpye card converter for the SMS II are now dashed.
