Any flat (ribbon) cables sneaking out of the vents on the side of the machine, or above the ports in back? Or has the battery cover perhaps been replaced with a DB-25 connector?
The symptoms suggest missing ROM chips, or poorly seated ROMs. This could happen normally, or there could be an upgrade in the machine which plugs into the ROM sockets, which has come loose.
If you find a card in there with a cable that terminates in a connector that looks like a mini-centronics (but isn't) please let me know. It may be the docking card for an Outbound Laptop Model 125. If it is, there will be no ROMs in the machine, but the docking card is unobtainium and I've been looking for one for a while.
More likely, there's a SCSI upgrade in there that has come loose, but I keep hoping for the docking card...
