Gameplay video

Trivia:
1) Player would enter input using a rotary telephone controller, and output was displayed on the computer's 35×16 dot matrix cathode ray tube.

2) Random-access memory (RAM) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory
3) Graphical interface or GUI, is a type of interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces which require commands to be typed on the keyboard.

4) Emulated in: Edsac simulator (only simulation).
