Here's an E-mail Q&A between the creator of the Atari Jaguar WebTV Adaptor (codenamed "Cortina" ) board and Ted Rusniak.
1.) Do you have or know where I could obtain the source code that allows the Cortina to communicate w/ the Jaguar? What state was the Jag code when you stopped working on it? What worked and what did not work?
- I'll look around and see what I have when I get back home next week. I'm not very hopeful, but it's possible that I still have the latest
firmware. I believe that on the Jag side, all that was written was test code - to see that the Cortina worked. The cortina itself worked
2.) We have a floppy that came w/ the Cortina's Protocol Rev. 2.2 22 Sept. 95 that you wrote some of the 8051 code onto the Cortina--the floppy has Cortina Rev. 4 written on it in pencil.
- I actually wrote all of the Cortina 8051 firmware, designed the board, had it laid out (at my expense), debugged it, etc..
3.) Where did the name Cortina come from?
- The project manager at Atari (for whom I worked as a consultant) was a friend of mine - Trevor Pearman, a British dude. Jaguar is a fancy British car; Cortina is a really cheap British car, made by British Ford.
4.) How was it (Cortina) going to run on the Jag? Interface cart?
- Cortina connected to one of the proprietary ports on the back of the Jag, and provided the ports necessary to turn the Jag into an internet browser. It provided a keyboard port, a mouse port and a serial port for an external modem. I don't remember too much about the goofy Jag serial port, but the Protocol description that you have should be enough explanantion.
5.) Do you have the encryption software?
6.) Is there anything you'd be willing to give up? Info, files, programs, etc?
- I wouldn't have anything except possibly the 8051 source code - which you appear to have anyway. I do not believe that Atari ever got a browser written for the Jag, as no one (except foolish me) in the valley would do business with Atari.
7.) Also on the back of your card it says "Cortina Self-Test Loopback Connectors" I did get a old school keyboard plug, 25pin male connector and 2- 9pin female connectors.
- I don't remember anymore how the loopback worked, though I guess that the mouse port looped back to the keyboard port, and
there was some sort of loopback on the serial ports. Generally, the purpose of the loopback was to check out the hardware during
manufacturing. I'm pretty sure that I documented the loopbacks in the firmware sourcecode on that floppy that you have.
8.) How many prototype Cortina's exsist?
- I built 6 or 8 of them. I do not believe that any more were built.
4.) Was it finished? I'm guessing it was since you said that you never received you final payment after completing it.
- Cortina itself worked perfectly. (Cortina itself was merely a port expander, providing the ports necessary to connect a Jag to a keyboard, mouse, and modem for internet connection.) But I don't think the browser code was ever written.
Thanks to Ted for the interview. You can see some pictures of Ted's Cortinas here.
