[Yaesu] What is it?

[Bob W7AVK]

Gang - Came up with an interesting Yaesu NOS pc card.  Has Yaesu Musen
F2527000A part number etched on it.  Its about 4.5 by 11 inches with a
couple dozen ICs, several of the 40 pin type and in sockets, and about
24 various size cable connectors around its parameter.   One of the
large ICs is a 80C85A [CPU chip] and three are 8255AC [Input / Output
chip]  which leads me to believe its some kind of computer or control
card.  But for where or which radio?  Any ideas?  Anyone what to make an
offer?

Thanks,
