More news in the front: - Opening the equipment, I took off one of the input boards, and discovered a bunch of 7404s going to 374 and 8255. I suppose these are the inputs. After mapped the inputs, I tried to put it high, but the analyzer always complains of loss of the Q3210T not connected, and LSA with no clock... Anyone can help? An instruction manual or some tips of how this thing works, would be very appreciated!!! -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
