legacy gateway profile3..

I just got a stripped down Gateway profile 3.
pt.no 3500944.

sticker on mb // 40-b20200-d310
v11kmpp81kod3

cpu+fan are missing (socket pga370)
no hd..
no rom drive
Floppy dd still in it
No card holder

This machine runs on 12v so would be perfect as auxilliary gps display.;
Just put in sdram 133mhz x 128mb +256mb. (mem is maxed out at 512mb ,)
just cannot find support info for this beyond the ram needed .

Hoping to install Linux Lite. or if not then Puppy.

Am I off the wall or have I got a slim chance of getting this thing going .
Mostly need manuals and data .
