They work just fine, but will load and save files in Commodore file format (which is not clear text ASCII – more on that later). LOAD and SAVE commands have been tweaked to reference the command line structure. Be careful with certain POKE commands though as those may call system routines that might not be implemented. Other than that, you can start typing like on a real machine.

all commands typed in must be CAPITALISED.

There are however a few important differences between a C64 emulator and this implementation: When you run the binary it will bring up something like the standard BASIC command prompt we’re used to seeing on the Commodore 64. Here’s how to copy the binary over (this will ask for your administrator password): sudo cp. The added benefit is that the path to that folder is already in your local $PATH variable, and as such you can simply type “cbmbasic” from any location when you’re on the command line. That’s where common command line utilities are installed on Mac and Linux systems. If all goes well you should see something like this:įor easy access, copy the binary over to your /usr/bin directory. You can test if it works by calling the binary without any parameters like this. We’ll do it using the chmod command: chmod +x. To make it executable, we’ll have to tweak the file permissions – otherwise our operating system won’t be able to run it. Enter “make” at the command prompt, and after a few moments you should have a file called “cbmbasic” without an extension in the same directory.

It includes a MAKEFILE so there’s no need to mess with any parameters. Using your Terminal app, navigate to your unZIPped folder. You might be able to bring those components in using the Homebrew package manager. Downloading Xcode will ptovide you with an excellent (and free) IDE as well as the command line tools needed to do that (gcc, make and several other goodies). You need a few utilities installed your your Mac to be able to compile files. Once done, you should see a directory structure that looks exactly like the repo on GitHub. GitHub provides a convenient way to either clone a repository on your local machine if you have GitHub for Desktop installed, or you can download a ZIP file and unZIP it somewhere on your system. You can get the full source code on GitHub – it works a treat!įor those who don’t quite know what to do with it, here are some instructions that’ll help you get CBM BASIC up and running on macOS. They’ve adapted the original BASIC v2 as featured on the VIC-20 and C64 with additional routines so that it works natively on modern machines. Did you know you can run Commodore BASIC v2 on your Mac and Linux systems as a scripting language? It’s true – thanks to the marvellous efforts of Michael Steil and James Abbatiello.
