One week ago everything I knew about the Atari ST could fit in this sentence: Who has room for that sort of stuff? Apparently not us says my wife. For this tutorial we are going to use Hatari. Okay, right about now, if you are like me you are probably asking yourself what is up with the crappy borders around the Desktop, I know! Here is the next steps to iinternals your Hatari installation souped up:.
Intrrnals this bit we are going to use the assembler called DevPac3.
Atari ST: Internals – Computing History
If you download Devpac and it comes as a directory of files: My installation was giving me troubles because it wanted to be run from the floppy drive. You may get errors when starting DevPac. PRG from the floppy from now on. PRG and double click it to run.
You should now be seeing this:. Your default settings for DevPac should be good. There is just one thing we want to make sure is set. You could always just save this code to disk in your hard drive folder then load it from DevPac but then you would miss out on the satisfying clicky sounds that the Atari ST makes while you type. Now that you have the code in memory lets assemble it! And now you should see this:. We actually did atri, look in the top left-hand corner… no closer, look there is a diagonal line there!
Okay, you are right I should have warned you at the beginning of the article that the program was lame.
Atari ST – Deskthority wiki
But it is understandable and digestible for a first program. Press any key to exit once you are done soaking in the wonderful line. Here is a quick rundown of the code. In the first section of the code we are just creating aliases to offsets and commands. Next we jump to the subroutine jsr initialize which sets us up for Super User mode.
Line A is the package of drawing calls we are using. There are other ways to draw on the Atari ST. I think these are the fastest least portable graphics calls any greybeards to correct me? The weird thing about that call is that it is happening with the dc command which is just putting that data directly into our code instead of using some sort of call opcode. We do that in our next section to setup the parameters to the draw line function.
Then we finally call the draw line function on line In other ways its a bit clumsy. A dark shadow falls over me when I think about all the hours of work spent by Atari ST engineers to build something almost lost to oblivion. The silver lining is the amount of love that still exists by a select few fans of the Atari ST. I wrote 6 games for the ST, and it was a great computer.
Neil, you are my hero. Releasing after 16 weeks then moving onto the next thing sounds like a dream. Such memory recall… damn, all those traps and stuff… why not try GfABasic, was over here quite popular! I felt like I came atarii far I might as well make the plunge into 68k.
Real men programs a ZX Internala in Z80 assembly! I never meet an Atari ST, but I know that is an amazing computer. Also, the AY sound chip always does nice chip tunes… Good luck doing programs for old machines!
The Atari ST Internals
Aw, you like the Atari ST interhals chip?! It has its charm. The chip I really love is the one in the Sega Genesis. I went back and did some work on Atari a arari years ago. Yes, I even remembered the CPU cycle counts for most instruction forms. I have a copy still lying around: I used to put touchscreens on those Atari monitors. I created my own widgets, direct manipulation GUI, and used them to create the first graphical point of sale software.
Nick Colley wrote the code in C. Cool, thanks for the tips Oberje. I might try out TurboAss too, it suppose to do real time assembly as you edit code. Your email address will not be published.
