Harry Potter Posted October 25, 2017 Share Posted October 25, 2017 I want to learn to program the Atari using cc65 and need memory maps of the used RAM locations, the I/O and the kernal routines. That's all I need. Where can I find them? BTW, I have the Mapping the Atari book, but all its contents are contained in one big chunk of the book, and that makes it hard to navigate.

dmsc Posted October 26, 2017 Share Posted October 26, 2017 Hi, I want to learn to program the Atari using cc65 and need memory maps of the used RAM locations, the I/O and the kernal routines. That's all I need. Where can I find them? BTW, I have the Mapping the Atari book, but all its contents are contained in one big chunk of the book, and that makes it hard to navigate. For the hardware locations, best reference is the Altirra Hardware Reference Manual, you can download the PDF from http://www.virtualdub.org/downloads/Altirra%20Hardware%20Reference%20Manual.pdf For the OS, there is the Operating System User's Manual, download from http://atariage.com/forums/topic/127483-atari-os-and-hardware-manuals-get-them-here/ 2 Quote Link to comment Share on other sites More sharing options...

+slx Posted October 26, 2017 Share Posted October 26, 2017 You might also want to look for "Mapping the Atari" which is a bit more accessible than the two above. It's available online from several websites. There a "Master Memory Map" as well but I haven't used that much. "De Re Atari" is good as well. 1 Quote Link to comment Share on other sites More sharing options...
tep392 Posted October 26, 2017 Share Posted October 26, 2017 I second De Re Atari for general technical info on how the Atari works. If you are just learning the Atari then this book will give you a good idea how the machine works. You can find it online. Quote Link to comment Share on other sites More sharing options...
Harry Potter Posted October 26, 2017 Author Share Posted October 26, 2017 I have Mapping the Atari, but it doesn't divide its information well: most of the book is in one huge chapter rather than sectioning off the information by functionality. 1 Quote Link to comment Share on other sites More sharing options...
phaeron Posted October 27, 2017 Share Posted October 27, 2017 Use the OS Manual. Mapping the Atari lists too many internal details of the OS and DOS 2.0S and doesn't distinguish between the memory locations that are and aren't supposed to be used by programs. 1 Quote Link to comment Share on other sites More sharing options...

That results from it being a memory map covering everything in the order of addresses. Maybe Im just partial to it because it was the one I used as a teenager. Today I find it convenient for quick lookups, back then I read it cover to cover Todays luxury is that you can freely use all three and search through the PDFs. 3 Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted October 27, 2017 Share Posted October 27, 2017 Agreed. Physical copy of Mapping the Atari is still permanently on my desk after 25 years and what can't be found via numerical lookup can be found in "Index by Label". If I had a hard-copy of Avery's Hardware Reference Manual, I'd have two Atari books permanently on the desk. 3 Quote Link to comment Share on other sites More sharing options...

You know, fr some reason I still prefer thumbing through pages of paper, as opposed to searching PDF for these old reference manuals. Don't know if it's nostalgia, or if it really is easier having the real books. 4 Quote Link to comment Share on other sites More sharing options...

Don't know if it's nostalgia, or if it really is easier having the real books. Fully understand that, nothing beats sticking a finger between pages to mark your actual position, I n very got the hang of digital bookmarks, though I really have come to like the search function. I also do some programming on the road and dont like to lug my precious copies of Mapping the Atari with me (and there isnt a bound copy of phaerons manual yet). 1 Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted November 3, 2017 Share Posted November 3, 2017 Further to my previous post, the imagined scenario magically came true: Seriously: massive thanks to Robert Stuart of Excel magazine who sent me this spare two volume copy of the Altirra Hardware Reference Manual as an early Christmas present after printing the document for himself. A fantastic, thoughtful and genuinely useful gift. 11 Quote Link to comment Share on other sites More sharing options...
