If you have an older SGI that has the DB15 keyboard connector, and you don't have any classic SGI keyboards (pre PS/2) there are some options.

https://www.drakware.com/

Drakware has a "Indigo to USB" adapter that works on all pre-PS/2 SGIs. You just have to go from DB15 to DIN6 (for the drak adapter).

Here is a diagram I created to do that. You can by a PS/2 extension cable from Amazon and cut it in half, using the Male segment. You can also get a DB15 male connector.

This works great in my 4D/320.

I would have loved to buy the USB->Indigo adapter, but they've been sold out forever.

Ended up spending more than I did for my first car (it was a cheap car!) for a real Indigo keyboard and mouse :)

And yes - loving the big SGIs, and the Lisa photobomb

Thank you for the diagram!
Quite nice that someone has made an SGI-to-USB converter. I have a couple of the original SGI keyboards for use with my R3k & R4k Indigos and my various PowerSeries beasts. I also was lucky enough to get the 2nd prototype of Randy's SGI-to-PS/2 converters back in the day (I collected all my SGI gear in the early 2000's).
