Message #1 Posted by Greg on 26 May 2003, 11:48 p.m.

Does anybody can help me with connection diagram for HP65 card reader head. 4 of 5 wires on my card reader came loose. The colors of the 5 wires are: black, red, orange, yellow and blue. I can see three of the wires go to a 20 pin IC (pin 7, 8 and 9). Thanks, Greg
