You're screwed.  The GS Smart Port is the most sensitive part of the GS
motherboard.  I used to repair Apple II's and a guy I worked with blew out
three of them.  Plugging the cable in when the system is on or reversing the
cable (done usually when connecting to Disk II with a new cable) causes the
smartport support circuitry to blow.  Consider yourself lucky - most cases
result in a completely disabled GS.  Unfortunatley, unless your good at surface
resoldering and can get access to custom made chips for the GS, your only
course of action is a motherboard replacement.
