Simon was a relay-based electromechanical computer, described by Edmund Berkeley in a series of thirteen construction articles in Radio-Electronics magazine, from October 1950. Intended for the educational purpose of demonstrating the concept of a digital computer, it could not be used for any significant practical computation since it handled only 2-bit numbers (values 0 through 3) and had only 32 bits (16 2-bit registers) of memory. A working model was first built by two graduate students at Columbia University for less than US$300 ($3,650 in 2022 dollars) in parts.[1] Some have described it as the "first personal computer",[2] although its extremely limited capacity and its unsuitability for use for any purpose other than as an educational demonstration make that classification questionable.
