There is only one sticker on the card
that says "1990 LTI; All Rights Reserved;
I believe LTI is Lapis Technologies.
They made video cards for the Mac. I would guess it is probably a video
card of some kind. Many of the older full page display cards had 9 pin
connectors. I don't know if they used a standard video output or if they
had to go to the monitor they were meant for.
Since the board is blue, I figured that its
probably a prototype of something, maybe a video card?
Probably just artistic license on coloring the board. I have seen blue
video cards before in the Mac.
