Well, it looks like one of those memory/multi-IO/clock boards like the AST RAMPACK+. I would take a look at this site (which you might already know):
When I was looking for jumpers, etc., for both the AboveBoard AT and BOCARAM I have, I started here. Maybe if you browse the links, something will pop-up. I know that these boards often have special drivers for expanded memory; extended memory should just "show up". I would hope that the other ports/devices (clock, parallel, serial and game) are at standard PC addresses.

I got this (currently exploded) mystery RAM, RTC, and I/O board out of
a dead Sanyo luggable the other night, and once I replace the burned
up tantalums I'd like to put it in my 5150 so I can get a full 640k of
Question is, does anyone know what this board is? It's a completely
anonymous board with not even an FCC ID to go off of. I'm assuming the
RAM is at least strapped right; all the banks are full which should be
384k, and the Sanyo was a 256k machine = 640k.
Here's a couple pictures; one's an actual picture of the card and the
other is a simplified TULARC/TH99-esque vector of what's on the board.
