The Jaguar Server is a independent Atari Jaguar Development Solution by Roine Stenberg - Istari Software.

This page will bring you news, updates and information about the Jaguar Server project and related items.

The Jaguar Server is an unofficial development tool that provides you with the hardware and software needed to create your very own programs for the amazing 64-bit Atari Jaguar Interactive Multimedia System, using an ordinary Atari Computer connected through the cartridge port.

Jaguar Server Hardware for the Atari computer.

001229 - First - sorry for the lack of updates in the past 1.5 years!!
Every once in a while a get an E-mail about the Jaguar Server. I think it´s about time that I write something about it´s status here.
I have built my last Jaguar Server and they are no longer availible.
But as people still have some interest in the the Jaguar I am thinking about doing a large update to this site with sourcecode, development tools etc. Lets see what happens in the near future!I
My e-mail adress is still

990521 - Well, another year has passed since the last update...
I´ve got a few E-mails these past two weeks about the status of the Jaguar Server. I guess that Realityman´s new Emulator project got some people interested in this almost forgotten console named "Atari Jaguar". Some people asks about the PC-version. I´m very sorry to say that I never finished it. I did the first few steps on a prototype on a breadboard but I lost interest in it when Atari died. I will NEVER finish it now..... Also, I still have 8 breadboards for the Jaguar Server lying here, but no components on them at the moment. Have no clue on what to do with them at the moment..... Some people might still be interested perhaps ? I´ve also updated all the filelinks (I think), happy downloading.
