OREGON TRAIL: Going under the hood with the 1977 mainframe version

A review of the 1977 mainframe version of Oregon Trail. The program is, arguably, the greatest title of educational software. We'll take a look at the origin, source code, and play of the version that ran on a CDC Cyber 70, plus go over some of the tweaks I had to make for my homemade clock- and timer-less 6802 computer. My computer uses the second BASIC devised by Microsoft (for MITS), so any of its 8-bit descendants (Applesoft, Commodore or Atari BASIC, TRS-80 Color BASIC...) will handle the code easily. https://www.seevid.ir/fa/w/Z9Q6ed6YT04 Intro https://www.seevid.ir/fa/w/Z9Q6ed6YT04 History https://www.seevid.ir/fa/w/Z9Q6ed6YT04 BASIC Listing https://www.seevid.ir/fa/w/Z9Q6ed6YT04 Timing Modification https://www.seevid.ir/fa/w/Z9Q6ed6YT04 Trail West https://www.seevid.ir/fa/w/Z9Q6ed6YT04 Oregon Trail Demo https://www.seevid.ir/fa/w/Z9Q6ed6YT04 Outro SOFTWARE Oregon Trail and Trail West for MITS Altair 680 BASIC: https://www.vanportmedia.com/hm68/games/ Trail West for VIC-20: https://www.vanportmedia.com/PAL-1/cbm/ DOCUMENTARY (86 minutes - professional!) https://www.seevid.ir/fa/w/8QbjlHeoLdc PLAY-THROUGHS https://www.seevid.ir/fa/w/NAI8Ysqbq7E https://www.seevid.ir/fa/w/g8B-JjzbthI PHOTO CREDITS Creative Computing magazine, May 1978: https://archive.org/ Don Rawitsch, et al., Carleton College, 1971, From the collection of: The Strong National Museum of Play https://artsandculture.google.com/story/the-oregon-trail-mecc-and-the-rise-of-computer-learning-the-strong/EAUBA3oJZQm2Kw?hl=en HP-2100 -- http://computermuseum.informatik.uni-stuttgart.de/pics/hp2100/hp2100.jpg PET -- https://vintagecomputer.ca/ TRS-80 -- https://www.classic-computers.org.nz/collection/trs-80-level1-1920x.jpg A2 -- https://www.apple2history.org/wp-content/uploads/2008/11/Apple-II-cassette-TV.png ET-3400 -- https://www.computinghistory.org.uk/ INTERVIEWS https://www.vice.com/en/article/the-forgotten-history-of-the-oregon-trail-as-told-by-its-creators/ https://archive.org/details/micro-ed-software The Spartan Conditions here: Camera: obsolete iPhone 5s Microphone: castoff USB mic from a karaoke machine Screen Recording: SimpleScreenRecorder for Linux (free) Screen Capture: Screenshot (part of Linux Xubuntu) Video Editing: kdenlive for Linux (free) Audio Editing: Audacity for Linux (free) In other words, if I can do it, so can you. :^) Music: (c) & (p) 2022, David H.
