I have expected that you will be very stressfull before you see my answser
I'm trying to launch the maximum of things on the board, but I have some trouble with compilation on some demos that were inside the SDK. In addition, without the joybus board, you can't clearly get everything of it. I have just prepared a basic indy with 5.3 and IDO before installing the OS2.0K, just to test the card. SDK documention is so crazy that I certainly need a lot of time ot investigate all files and README to find every bit of story about this board.
Thanks to an old post on the Neko forum for some command lines about Ultra64 board....
But your right, this Ultra board is very special, especially to have a thing that was not labelled Nintendo64 but Ultra64, a 1995 piece of history. Good job for the SN devkit
. I have a 75% complete Partner Kit with an early ALPS 64DD dev drive (missing ISA / PCI board), but the ultra board is clearly easier to get working for a SGI fanatic.
