Strange i-con Unibus (?) board

[Sean Caron]

On the back of Roe's question; didn't want to hijack his thread.

I was browsing eBay and came across this very unusual looking Unibus card
(?)

http://www.ebay.com/itm/Vintage-Computer-Memory-Digital-DEC-logo-1216988-board-from-PDP-11-or-VAX-/261685664915

I'm really curious what all those SIP hybrids are running down the one side
of the board. I see it's got no less than 8 74181 ALUs so I figure this has
got to be some kind of processor?

Perhaps a prototype or simply an obscure hop-up processor for Unibus
machines similar to some of which were marketed for Q-bus with i.e. MC68k,
NS 32k, MIPS CPUs (KN210), etc.

I tried to do a little research about i-con on the Web but I'm coming up
blank.

Anyone know what the heck this thing is? Just curious.

Thanks,

Sean
