panamajoe Posted July 21, 2014 Share Posted July 21, 2014 I bought a Jaguar with two switches. One that changes between PAL and NTSC and one that lets me access the JagOS... unfortunatly i have no idea what i can do with the JagOS mode... can you enlighten me?

82-T/A Posted July 21, 2014 Share Posted July 21, 2014 I don't know, but that looks awesome. I wish my Jaguar had extra switches! Quote Link to comment Share on other sites More sharing options...
+madman Posted July 21, 2014 Share Posted July 21, 2014 A ROM replacement that allowed you to upload .JAG files to the Jaguar. I think the upload code only ran on Atari ST computers. 2 Quote Link to comment Share on other sites More sharing options...

+BitJag Posted July 21, 2014 Share Posted July 21, 2014 Cool find. Here is some "Googled" information about it. http://www.zophar.net/fileuploads/2/10652sjsfs/JaguarServer.txt http://laurent68k.free.fr/Site/Jaguar.html Like what madman said, Looks like it was a set of developer tools for programming Jag games on the Atari ST and Falcon line of computers developed between 1997-2000. The first link includes instructions on how to perform the modification that your console may have. If only I still had an ST.... 2 Quote Link to comment Share on other sites More sharing options...
panamajoe Posted July 21, 2014 Author Share Posted July 21, 2014 (edited) Best thing about that find is, that it came with a CD attachment and both, the Jag and the CD, set me back a mere 60 Euro... And yes: the CD unit works! Edited July 21, 2014 by panamajoe Quote Link to comment Share on other sites More sharing options...
+save2600 Posted July 21, 2014 Share Posted July 21, 2014 I think it's pretty useless as it caused you to post an oversized and upside down pic of the screen. Quote Link to comment Share on other sites More sharing options...
Zerosquare Posted July 21, 2014 Share Posted July 21, 2014 Where did you get it from? The JagOS ROM is pretty rare. Quote Link to comment Share on other sites More sharing options...
TXG/MNX Posted July 22, 2014 Share Posted July 22, 2014 http://laurent68k.free.fr/Site/Jaguar.html Here you can find the rom i think i got it also inside a jaguar. If i remember correctly you can use a normal bjl cable to upload stuff. The full dev package written for this can be found on the link above. Most things were coded in devpac and pure c on Atari I think. Maybe try to find this person and get him onboard of AA. Quote Link to comment Share on other sites More sharing options...

panamajoe Posted July 22, 2014 Author Share Posted July 22, 2014 Where did you get it from? The JagOS ROM is pretty rare. I bought it locally from a guy who did get it from his nephew (who left germany some month ago...). He had two fully working Jaguars (one with JagOS, the other one without) and a CD attachment. No games unfortunately... Quote Link to comment Share on other sites More sharing options...
panamajoe Posted July 22, 2014 Author Share Posted July 22, 2014 Sorry in french in the text : http://jaguar-64bit.pagesperso-orange.fr/Developpement/KitLight.htm Ah! very interesting! Thank you! Quote Link to comment Share on other sites More sharing options...
TXG/MNX Posted July 22, 2014 Share Posted July 22, 2014 It's an old kit, these days use a normal jag and skunkboard... I got a modded jaguar like this: http://rdemming.home.xs4all.nl/Atari/ a modded Jag with 5 OS systems. 1) original OS 2) BJL os 3) Stub 93 4) Stub 94 5) JagOs On that side you can download the JagOS rom aswell...

ST-Oldie Posted July 22, 2014 Share Posted July 22, 2014 As far as i remember, JagOS contains also some functions which can be called from a Jaguar binary. Not really a full OS but like a first step. Quote Link to comment Share on other sites More sharing options...
TXG/MNX Posted July 22, 2014 Share Posted July 22, 2014 For a nice OS you need to folow EMUTOS development there is a one-man project that ports it to the Jaguar. Quote Link to comment Share on other sites More sharing options...
ST-Oldie Posted July 23, 2014 Share Posted July 23, 2014 I think, EmuTOS is a little bit to big for the Jaguar startup EPROM. The space reserved in the addres space was only 64KB. I remember i discussion about a OS for the (never released) CF card adaptor. EmuTOS can be used as a file browser and starter of CF based games and can also provide a API because every CF based game can lay on the presence of this API. EmuTOS can also expanded to start a .jag from CF card. I see more use of EmuTOS for hardware extensions. Quote Link to comment Share on other sites More sharing options...
TXG/MNX Posted July 23, 2014 Share Posted July 23, 2014 Hi EMUTOS can run from cart (skunk) or other cart, can be loaded from CD. I find it an interesting project. TOS on ST is about 512Kb so would leave 1.5Mb free of RAM. This is one of those things like JagOS functionality not much people would maybe use it but its to interesting to let it die. I have seen a TOS cartridge in the past that never made it to production, the idea was nice to see TOS running on the Jag with mouse (kbd) could be aswell... When EMUTOS has a ramdisk like the build version has now and it could be use input from mouse/kbd (not implemented yet) it would be nice, atleast for me and a few others. Its a free (no cost) project so why be negative on someone who has fun doing this... 1 Quote Link to comment Share on other sites More sharing options...
VladR Posted July 24, 2014 Share Posted July 24, 2014 While there are plenty other and more comfortable options these days to code for Jaguar, this one seems to be actually the only one to code natively on Jaguar , no ? Still, without a keyboard, entering all code through the gamepad ... Wasn't there ever a way to attach some sort of keyboard to jag ? How much does this thing cost these days ?

ST-Oldie Posted July 24, 2014 Share Posted July 24, 2014 Hi, EMUTOS can run from cart (skunk) or other cart, can be loaded from CD. Yes, you can. But EmuTOS allown is not so usefull on the Jaguar for most of the people. And i think, it will be not possible to use it for playing Atari games. The hardware and also screen layout is to different. Matthias Domin told me, the GPU was not fast enough to convert "on the fly" the plane format of ST low resolution to a non-plane bitmap on the jagar. I find it an interesting project. TOS on ST is about 512Kb so would leave 1.5Mb free of RAM. Yes, i think also it is a interesting project. And if it works, it can inspire other to projects with EmuTOS as a base. This is one of those things like JagOS functionality not much people would maybe use it but its to interesting to let it die. I think, most of the jaguar owners will not use EmuTOS. Only if it comes together with something usefull. Maybe other people got some interesting ideas how to use EmuTOS if it available. Is there the danger, that this project will die? I have seen a TOS cartridge in the past that never made it to production, the idea was nice to see TOS running on the Jag with mouse (kbd) could be aswell... I remeber the TOSonJag Catridge which was published (but not developed) from Matthias Domin. It was a old project with IDE and PS/2 ports. There was also a CF card adaptor which was never published. But i did not know if this card has connectors for mouse and keyboard. When EMUTOS has a ramdisk like the build version has now and it could be use input from mouse/kbd (not implemented yet) it would be nice, atleast for me and a few others. I think, the ramdisk is really needed to "customize" the system. It allows EmuTOS to boot and load drivers or add software without the need of another "standard mass storage" or a modified EmuTOS. Load drivers from the ramdisk will allow you to have one EmuTOS for the Jaguar without changes in the source code for different projects and hardware. Its a free (no cost) project so why be negative on someone who has fun doing this... Is there someone negative about this project? I only think, it is not so interesting for most of the jaguar owners. It is a little bit special. While there are plenty other and more comfortable options these days to code for Jaguar, this one seems to be actually the only one to code natively on Jaguar , no ? It should be possible to use the existing development system from Atari for Atari computers together with EmuTOS on the jaguar itself. But then you need a additional mass storage. All parts of the development system together are to much for a ramdisk with enough ram unused to start a program. But on the other side it is possible to use the VDI for graphics and AES for a user interface. So you have a graphic lib with EmuTOS. And if the VDI uses the GPU, it can be a fast graphic lib. But the VDI screen driver can only write to the screen, not to bitmap. Having 2 bitmaps, one displayd and one which is drawn is not possible with the VDI without modifications. So there are enough room for interesting ideas, but there is also always a little bit work needed to realize the ideas. Still, without a keyboard, entering all code through the gamepad ... Maybe it is possible to have a virtual keyboard like smartphones and tablets have. If this keyboard injects the keys into the VDI or AES ... The only problem is, the application with the top most window get all events. But i expect nobody will edit huge amount of text with such a virtual keyboard because you must use the gamepad as a pointing device for select a key. Wasn't there ever a way to attach some sort of keyboard to jag ? What about the never released CF card cartridge? Does this device has connectors for a keyboard? Together with a mass storage (and maybe a ne2000 clone nic) it was a very nice base for EmuTOS. Regards Michael Quote Link to comment Share on other sites More sharing options...
+CyranoJ Posted July 24, 2014 Share Posted July 24, 2014 Guess he hasn't played Bubble Bobble then.......

Matthias Posted July 24, 2014 Share Posted July 24, 2014 Hello! Guess he hasn't played Bubble Bobble then....... I worked on that TOSonJag-project about 15 years ago, at that time my knowledge of programming the RISC-processors as well as my knowledge about balancing all the Jaguar's processors was very very limited, so i had asked a friend to code a GPU-subroutine doing said bitplane conversion. Seems something went wrong. Best regards Matthias 4 Quote Link to comment Share on other sites More sharing options...

The first link includes instructions on how to perform the modification that your console may have. If only I still had an ST.... John Carmack made statements that he "suffered" developing for the Jag originally using a Falcon until the dev tools could run on NeXTStep. I don't have a link at the moment but it's part of a bunch of his collected interviews - mainly with Alex St John - compiled into a PDF. So perhaps the OS dates prior to 1997 during the Jaguar's original development and release. Quote Link to comment Share on other sites More sharing options...
Zerosquare Posted July 26, 2014 Share Posted July 26, 2014 From JaguarServer.txt: The Jaguar Server project started out in August '94. The goal was to make a cheap developer kit for anyone that wanted to program for the Jaguar. Atari's own developer kit was $5500 and that was WAY to much if you just wanted to hack and program the Jaguar just for the fun of it. 2 Quote Link to comment Share on other sites More sharing options...
