There was a converter a few years ago that went from 'onyx' to PS/2. That seems to have vanished from ebay. I have some and they say "CKCOMPUTERSYSTEMS" on them - perhaps your friend can chase that down.
The Drak goes to USB which may be better or worse than the CK adapter depending on your keyboard fetish. Real SGI 'onyx' devices pop up on ebay every once and a while. Make sure they are not SGI PS/2 (which Indigo2 and all later SGIs actually used) - the 'onyx' style will have the mouse attachment to the keyboard itself (the computer just has one DIN connector for m/k not 2 like actual PS/2 devices). http://www.sgistuff.net/hardware/other/input.html <http://www.sgistuff.net/hardware/other/input.html> There are a very few SGI vendors around with parts. http://www.mashek.com/SGIparts/Indigo.php <http://www.mashek.com/SGIparts/Indigo.php> Lists some available. These may seem like high prices till you watch an ebay listing go higher. -andy > On Feb 20, 2022, at 11:47 AM, Jules Richardson via cctalk > <cctalk@classiccmp.org> wrote: > > On 2/20/22 10:36, Andrew Diller wrote: >> Indigo1 is not PS/2, even though the connector looks that way. > > Correct.
