  1. what's the difference between an Atari OS and the Altirra OS, basically what I want to do is to create a piece of hardware (like a calculator) with the OS to perform the task of a piece of software already built in on an eprom (or whatever/however you do it these days). Therefor, I will need the hardware made, software made and then sell the gadget publicly.
  2. I was wondering (as I have an idea), can the Atari OS be used in my own made 'small-device's', what I mean is what's the protocol with the copyright, would I be able to use the Atari classic's OS for my own ends, is there someone that copyrights need to be paid? I won't say what my idea is just yet, other than the use for what I've said. any info.......
  3. Just out of the idea for extra information, I originally learned how to write gr. 0 text to a gr.8 screen from Page-6 magazine issue 8 (the 1st issue I ever bought).
  4. The book: Complete and Essential MAP for the Atari contains everything in Mapping the Atari but also has some additional information in one of its appendixes and at the specific memory locations, such as SIO (pointed to from the INDEX), it describes DOS files and also self-booting disks.
  5. I haven't been following this thread so if I mention something that has already been said then please excuse me, but there are a couple of things a beginner can do to cause hacking problems, not so much to stop copying, but viewing or editing. For instance: The Break key can be disabled; see location 16 and 53774, The RESET key can be TRAPped, I can't remember how I used to do this, it's been some time, but I know location 9 can show you 1 way of preventing RESET accessing your BASIC program, also The CTRL-3 key during input can be prevented by TRAPing it to a particular line, and The BASIC listing itself can be disguised, I can't remember all of what you can do, it's been a long time, but you can start at location 138 & 139, see MAPPING the ATARI, and lastly; To make your BASIC program RUN immediately after LOADing it all you have to do is load your basic program into a word processor and at the bottom of your program insert the RUN command without a line number. Be careful what word processor you use because most good ones store additional information other than what you see, so it's best to use a very basic one, one that will suffice is SPEEDSCRIPT. Have fun.
  6. Very difficult to pick just 5, but... Atari BASIC (initially until TURBO BASIC appeared) Assembler/Editor Cartridge, where I began my machine-language adventure DOS 2.5 invaluable XL ART which was the only graphics package where you can stretch or bend graphics images, invaluable at the time when I first began to make demo's TextPro invaluable, also if you need a word-processor that doesn't save additional bytes in addition to your text-file, then SpeedScript. Very necessary for some applications.
  7. Yes, this one. I do understand how the colour is achieved via the use of PMG's, but I dis-believed myself because of how well it has been done, excellent... More games should be programmed like this. I always remembered/believed that the ZX Spectrum was better than the 8-bit Atari, only in this particular matter of achieving many colours in an equivalent of our mono mode-8 resolution, but now I see it can be done very well on the Atari, I now see, that in this particular regard that the Atari is as good (and if you take into consideration the Spectrum's colour clash) it is probably better. More fiddly, though, granted.
  8. Is it me or does maniac miner use mono graphics mode 8 AND have many colours? Perhaps it's just because I'm using a small'ish laptop, anyone care to expand?
  9. Thankyou rdea6, that's better, although I do still get a whining sound mostly I believe b4 a game is loaded.
  10. Is it my "new" laptop or is anyone else also having problems with the Atari800win emulator and Windows 10?
  11. I know it's by far not the best way, but what I used to use was Diskey II. I used to know all the hexadecimal codes, and so could follow the flow of the program as through the visual a sector-editor gives you. It's handy to have a copy of "Mapping the Atari - Revised" to hand and also a Machine-code/Assembly reference sheet giving you all of the Machine-Language codes and Assembly equivalents on a quick view card. Virtually all of my Demo's were created this way; Firstly, I would create the routine in BASIC & Assembly (a combination of the two) on paper, check thru it (in my head), double-check it thru, then convert the BASIC parts into Assembly, then enter it directly into the sector-editor. Obviously, no matter how hard one tries, you will always get bugs, which need ironing out (and I understand by coding your routines directly into a sector-editor this way quite possibly creates a few more bugs), but anyway, once the code was correct & bug free, I would write that back down onto paper for keeping, Or use a Dis-assembler to print it. Also, if I believe correctly, I think Diskey II was the one I used to access 720 & 1040 sectors (just not 720 Double-Density sectors), although I did have a Diskey version for D/D, even, though, with the amount of Double-Density utilities around it's not really any problem to convert.
  12. Thank you both for your information, I especially like the way you (bugbiter) go about this task, that's probably the way I would do it too. So I assume that when you transfer the .WAV file from its source to an 8-bit equivalent you transfer it into 2 nybbles, which occurs a question; I know the Atari uses 4-bit resolution, but how many bits resolution is a typical .WAV file?), also I know the Atari frequency's but not the typical PC frequencies that music is recorded at? Am I making sense?
  13. Hi, I was wondering if anyone new of a program & necessary hardware for recording digitized input on the Atari. I used to have a cartridge once upon a time which had a phone jack built into it, but as I remember I never got to upload anything. I've heard sound samples on our Atari and some it has to be said are quite poor, but I do know the quality that they can be & this is why I'm asking if anyone knows of uploading/making (so to speak) 'Quality' samples. Any help much appreciated. EDIT: I've no idea, but can sample files be transfered from the pc using SIO2PC?
  14. I'm not sure if these have been mentioned earlier as I haven't read every post, but I think a sequel to FLIP N FLOP would be great, NECROMANCER and MASTER OF THE LAMPS would be good too. There is also a modification I would like to see to 1 game, but I won't mention it yet as it is in my list of "TO DO" things, in time....
