In this punch cards #retro adventure, #punched #cards are used to make a laptop running Linux define, within a Common #Lisp interpreter, a recursive factorial function, and then we ... order 66 :) ... to be evaluated as an argument, displaying the result, with the latop acting as the "mainframe". The code for the Arduino, including a brief Lisp program to generate punch patterns, is here: https://github.com/KedalionDaimon/arduino-punchcard-readers/blob/main/punchreaderUNO20221227.ino
