An electronic checklist uses solid state readouts to display alphanumeric data such as would be found in a short but concise checklist. Operation of the checklist is enhanced by interfacing circuitry which contains page and line selecting features. A chip select decoder and a character sequencing counter operate in conjunction with other ROM addressing circuits to route characters from the ROM to the display. An emergency power supply circuit and a voltage regulator circuit are also given.
