Well I opened up my Exp Unit. These is no screen print to identify what chip is what, nothing. There are 2 x 74LS16 chips and so many via's that I'm having trouble following any path. The Schematics shows LS16 (36) P5 going straight to a P9 74LS74 but using my multimeter neither P5 of the LS16's appear connected to the LS74. Would photo's of the top & bottom of the board help ?
