SGI Indigo keyboard / mouse / converter wanted

[Andrew Diller]

Indigo1 is not PS/2, even though the connector looks that way. You need to have the "onxy" keyboard/mouse or get an adapter from Drakware. Plugging in a PS/2 device will harm the SGI and or the keyboard.

You can build your own but I don't have the details, perhaps Drak does and is willing to share them.

In absence of the genuine items they'd still be happy with a USB converter (at least for the time being), but it seems those are difficult to come by at present, too.
