Title:  Keycard Modification 
 

A technical bulletin, #160, was sent out recently regarding the modification  
that needed to be made to produce a modified keycard.  PLEASE DISREGARD
THAT 
INFORMATION; IT IS INCORRECT.  We know that to produce the best results in 
all situations, the information given in this technical bulletin, #160A, is  
correct.   
 
It has been found that the current keycard, part number 738-000061-001, will  
not function on the NEC APC IV and the IBM XT 286.  If you are using these 
machines, you will need to make modifications to your existing keycard to  
produce a modified keycard.  The trace specified on the drawing below, which  
is the back of the keycard, will need to be cut.  The drawing below is  
intended to be used as reference.  The trace to be cut is clearly marked.   
This modification will then allow a keycard to work in these machines.   
 
As further testing is done with PC clones, more machines may need the modified 
keycard.  If so, notification will be made.
