The Vicor parts aren't pulling up for me. One is marked with the Motorola 'M' also. These may be custom chips made for Motorola. Vicor is famous for developing power supply control chips - I'm guessing that's what these are. Probably flyback topology.

 

Here is the datasheet of MAX8211 for you!

 

The Maxim chip date code is 8841 - 41st week of 1988...
The Vicor K8839 could be 39th week of 1988..
The Vicor CS8904 could be the 4th week of 1989

I think those Vicor chips are custom made chips. Board was made probably sometime in 89 or 90, I'd guess.
