 PROBLEM DESCRIPTION:  Some ProFile Interface cards will not work
 properly when installed in the Apple IIGS. ProFile directory information
 might become damaged and cause the user not to be able to access data
 stored on the ProFile.

 CAUSE:  There might be an incomplete ground path through the card.

 CURE:  If ANY ProFile Interface Card is to be installed in an Apple
 IIGS, check first to see that a jumper, made of 24-26 gauge multistrand
 wire is installed between pin 12 of IC C6 (2716 EPROM-Apple Part# 341-
 0299) and pin 1 of IC B4 (74LS368-Apple Part# 305-0368) on the non-
 component side of the board. If needed, the jumper should be installed
 by a knowledgeable technician to assure proper operation of the ProFile
 when interfaced with the Apple IIGS.  The jumper wire should be just long
 enough to make the connection.  The technician should remove the EPROM before
 soldering, thus preventing any damage to the chip.
