Greetings; I don't know if its any form of blasphemy to do this. But for only $40, you can get a prebuilt convertor of standard PS/2 keyboard + mouse to proprietary SGI keyb/mouse bus for Indigo/Crimson. (The dude says Onyx uses them too, but I was kinda sure that was PS/2 like Indy. No matter) The adaptor guarantees an endless supply of working Granite keyboards and mice from Indys and upwards. I'm not a representative of the guy at all, but I think its damned useful and I figure some of you might too: chris 'at' ckcomputersystems 'dot' com Enjoy folks; JP
