Whilst actual human guinea-pig testing is done on new interfaces, it still does not make up the bulk of the design process. The joy of alternative operating systems, is the variety of Computer ? Human interface models available.Įven now, the modern operating system is designed from the perspective of the engineer. With hardware already a commodity, the way we interact with our computers is taken as a standard, and a given best-practice of design. Note: After a small break, here is another one of the articles for the Alternative OS contest.Īs we take time to look at the grand variety of operating systems available, it shows us that there is no one right way to ‘do it’. It was written using immense knowledge of the hardware and the tricks one could use to maximise speed. It wasn’t an OS written to run on a generic x86 chip on a moving hardware platform. In future posts will continue with more complex samples.GEOS managed to offer nearly all the functionality of the original Mac in a 1 MHz computer with 64 Kilobytes of RAM. The app will load and execute and you will see the results: Navigate to the colortest folder and select the colortest.prg file we created. So, start the emulator ( 圆4 or 圆4sc) and at the File menu entry select the Smart Attach Disk / Tape option. This makefile creates a file colortest.prg which is prepared to run on a C64. Rm -f colortest.prg colortest.o colortest.sĬheck that we used the TARGET variable to define the target platform for the compiled app. The memory address $d020 is used for setting the border color and the address $d021 is used for the background color so, we will set the border color to 0 or BLACK and the background color to 2 or RED. #Vice emulator mac codeSee that the makefile file has no extension.įor the first file colortest.c the code will be: #include Inside this folder we need to create two files: colortest.c and makefile. So, create a folder, lets name it colortest. We will create a very simple app to test if everything is fine. We installed a bunch of stuff and configured the environment so, this is the moment to see if we can make it work. This last will contain information related to the target platform you will compile to (C64, Apple, Atari, etc). The other variables inform to the compiler where will found the include, the libraries and the configuration files. #Vice emulator mac updateIf you installed on a different place, update the CC65_HOME variable. I asume that you installed the CC65 suit at a folder named inside your active user home folder. You will need to set at least the next variables: There you will execute the make command to proceed to compile the suite.Īfter a while the suite will be compiled and ready to proceed. Yes, as many times on your Mac, you will need to compile the CC65 suite previous to use it so, the next step is to downloaded it from the GitHub repository.Īfter that, open a terminal and move inside the uncompressed CC65 folder. This will allow you to proceed to execute the make utility very used for C compiling (and other languages too). #Vice emulator mac for freeTo properly make it works, you need the base development tools you can downloaded for free if you already do not have them installed the command line tools from the Apple Development site.
