The logic of the reader down to gate details and integrated circuit types is virtually complete. Additional tests and measurements were made on 256 bit self-scanning photodiode arrays. Eleven different types of printed circuit boards were designed. All special circuits for the machine were designed. These include amplifier and quantizing circuits for the scanning arrays, lamp servo amplifier for illumination control, as well as others. A new scanning array and lens mount assembly was designed. The layout for the keyboard and control panel of the reader is complete.
