HP 10529A Repair Question
I picked one these and it has LED's 13 threw 16 lit in the test mode
all the time. Problem points to U6. Quad 2 Input NOR Gate. TI SN4467, HP 1820-0328. When the output is low the Led lights up. It looks like the replacement would be a SN7433, Quade 2 input NOR with open collector. Can someone conferm this. Dose anyone have a cross reference to the HP IC part numbers for this model? Thanks RJ |

I show the 1820-0328 (SN4467) crossing to a SN7402. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
