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.

Hi all,
A friend of mine has just acquired an Indigo (R4k with XZ graphics option), but of course
it's the usual story and the keyboard/rodent had been lost. 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.
Does anyone happen to have a surplus converter suitable for these machines, and/or
keyboard/rodent? (according to sgistuff keyboard is p/n 9500801 and mouse p/n 9150800)
[side note: they mentioned a USB converter, but I'm pretty sure years ago someone had
implemented an adapter to PC-friendly PS/2 parts, too. I'm sure something like would
do the trick, too]
thanks,
Jules
