[AmigaNut08]

Hi,
 While doing a search on ebay for Amiga gear, i came across this interesting item.

http://cgi.ebay.com.au/AMIGA-500-UNRELEASED-MYSTERY-PROTOTYPE-DEVICE-2-NR-/320549206389?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item4aa238b975

Does anyone have any info??

The seller also sold another board similar to this not too long ago.

Sorry i didnt see that thread. I thought they may have been some sort of sound board at first.
