No, the 50 MB/s was with a Cyberstorm Mk2, testet on AmigaOS.
12 MB/s via Zorro is pretty much the maximum you can get at all. With
certain Chipset revisions upto 15 MB/s might be possible, if I remember
correctly what Klaus 'crest' Burkert told me regarding the PicassoIV
interface and the Zorro bus.
