Ok so now that I've gotten to the good stuff, I first started looking at the IC's.  The first one I notice was one labelled NextNet wireless expedience-AMOD D1GJ9-010.  This one was a bit hard to find any kind of information on at first so I skipped it for a moment and moved onto the next one that looked interesting, COLDFIRE MCF5307, which was alot easier to find a data sheet for.  The data sheet is nearly 500 pages long, but the short answer is its the main processor made by Freescale Semiconductor.  I'll see if i can summarize the stats at some other point in time.  The next interesting chip was what looked like the ethernet, SMSC LAN91C93l.  A non-PCI single chip Full Duplex Ethernet Controller.  The datasheet isnt quite as long as the processor, but I will condense it the best i can at some other point.  Now we get to the smaller IC's.  The next one I decided to look up was PULSE PE-68032, A ethernet interface controller.  2 ISSI IS42S16400B  DRAM CHIPS seem to be providing the memory needs. Another set of 74LCX16244 chips provide some line driving and a lone M29W160ET for some flash memory are also present.  Theres a handful of really small IC's but I can read the numbers so I will dig out my magnifying glass to get a read on those.  Theres also some shielding that I would like to get off an examine underneath.  I'm assuming any radio parts will be underneath there.  Next I am planning on removing the whole board and getting a good look underneath.  I did find a pdf of the original installation and operating manual that I took a good look at.  It had installation instructions for Windows 95.  Once I do get this board flipped around I would like to see the main connector and see about rigging up a cord to it.  At first I thought it was a plain CAT-5 cable and, I could probably still use one, but I want to know what im connecting what to were first.  Im still not sure what i can do with it as a unit, but Im sure something will come up.
