What is the reading between the 154's Vcc and Joystick ground? also, what is the reading between the 154's gnd and joystick gnd when seperated?In order to get it to this stage, I did what Len said at the 'EDIT' of your post, connected the '154 and resistors to +5v, and the hex chip Vcc to Z. But one major thing to note. I disconnected the wire which commons the ground of the new circuit to the ground 0v of the joystick, if thats connected nothings works at all, all y1-y6 are off. So how on earth is this new circuit getting power??? If the new circuit ground is not connected to the ground of the power source??
