Today I discovered a schematic of a cool circuit that I designed in the early '80's at IHSTL. The downside is that I labeled a shift register with the wrong part number. This is a 16 pin, parallel in, serial out, 8 bit device. I am guessing it was a CD4000B series device because this was an automotive application, needed the higher voltage and low power consumption. The key is that this device had the DO (serial) on pin 3. Any help is greatly appreciated.
