Not to mention that you have cross-posted in THREE forums...

It looks like it is designed to work with Altera boards - but it may be modifiable to work with BS2 / SX chips. Here is an attachedˇbrochure and other details:


I think for the level questions you ask, you should probably post your questions to SLS as many people here are only versed on Parallax products.
