At the request of a reader, I recently scoured the internet and my archival hard drives for an old CP/M nuclear simulation game, but couldn't find it.  I did, however, bump into some video which might really interest those readers who are also interested (or even passionate) about nuclear power simulation technology for nuclear training purposes. OakFlat.exe was a late 80s DOS simulation game created for consumer fun and education, where you control a nuclear reactor in order to produce maximum output while minimizing stress and damage on the reactor (and above all, avoid a meltdown). If you want to see this game, but you don't have DOS on any of your machines anymore, you can see a nice overview on a youtube video which is available which you can view when see this entire article by clicking on the READMORE link. We had a devil of a time finding this, so for historical and archival purposes, we are now maintaining the code for this shareware game on this site, available at this link: oakflat.zip Within the zip file is a DOC file that has all of the documentation on how to install and run this simulation. If the graphics look REALLY BAD to you, it is because there AREN'T ANY.  In the early days of DOS, screens were 80 characters wide by 25 lines high, so the animated graphic of the reactor was created by refreshing the screen with colored text blocks.
