Apple II ProFile Interface Card Modification for the Apple II GS
 
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 technician should remove the 
EPROM before soldering, thus preventing any damage to the chip.
