Here's something from the way back machine! How many of you even know what a floppy disk is? This is well before my time at Rollei so I don't even know what this software does exactly but I think maybe works with the projectors. The green part looks like some kind of software key. I have a feeling that this was expensive stuff at one time. For your collection? I have two boxes one with the software and key and one with the cable and demo software disk. I'm assuming that both parts are needed so selling together. No returns, and please don't ask me to split up this for the cable or key alone.
