I just recieved Two "Hendrix Main cards" and two matching IO daughter
boards. The Hendrix card has a 50 pin Centronixs connector on it while
the Daughter cards have a smaller "SCSI 2 ish" looking connector on
them.

The ebay ( errrr) auction i won was for what i thought was a SA4 card,
or some Nubus Protools cards.

Does anyone remember what the Hendrix Card was about, what interfaces
(442/882 etc) will work with these things. I can't find any mention of
them amongst the Digidesign "Legacy" Products.
