Questions about SampleCell I

[auahz]

Hello everyone,
some time ago I was lucky enough to get hold of a SampleCell I card and I'm now building a retro setup with my Performa 600. I have two questions about the SC1 card:

1. The card came with a piggyback card and according to this thread, it was needed for compatibility with Quadras. Was this the only purpose of the piggyback card? And what was the purpose of the mentioned even older non-Quadra-compatible piggyback card?
2. I know that the SampleCell 2.0 Editor also supports the SC1 card, but for true authenticity I've been searching for SampleCell Editor 1.x for a while now, but it seems to be non-existent on the web. Does anyone have the old SC1 disks and could upload them? Those would be worth preserving in my opinion.

Thanks in advance!
