I see that the autocorrect got me again. It is SimH that needs to be installed, not sims. We will be at Dymon in Kanata for April. The board room is now open. In preparation for the topic, you will need to be able to run a hardware emulator called SimH Windows: https://github.com/simh/Win32-Development-Binaries/blob/Win32-Development-Binaries/simh-4.0-Current--2019-03-30-98f6aae3.zip <https://github.com/simh/Win32-Development-Binaries/blob/Win32-Development-Binaries/simh-4.0-Current--2019-03-30-98f6aae3.zip> macOS: brew install sim The mac install requires home-brew, which will take a while to install. There are good sites for the sequence you will need to follow. this one will work for Mojave: https://dev.to/berry_clione/install-homebrew-on-macos-mojave-4m3m <https://dev.to/berry_clione/install-homebrew-on-macos-mojave-4m3m> You can safely ignore the zsh in favour of bash. For Linux, you can follow any number of blog articles. Here is an older one: https://mike632t.wordpress.com/2013/03/24/installing-simh/ <https://mike632t.wordpress.com/2013/03/24/installing-simh/> I’ll have the parts you need for the interactive session available to download at the beginning of the meeting. Do not wait until the last minute to get SimH installed.
