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

I think the Wombat adapter would work (?)

Jules,
I don't have a solution, only the same problem, but with a Tektronix
4200 series graphics terminal. Keyboards are rare, there is one on ebay
for $700, yikes!
However, I do have 2 of these terminals and one working keyboard.? Was
starting to go down the path of intercepting the startup, POST exchange
that occurs, then trying to adapt a common PS/2 keyboard.
I was looking for minimal capability, not perfect emulation.

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.

Correct. I was just pointing out that I think I recall someone years ago
implementing a converter between the Indigo's proprietary protocols and
"modern" (at the time) PS/2 keyboards/mice - and that one of those would
likely also be suit my friend's needs in absence of an even-more-modern USB
version.

have the "onxy" keyboard/mouse or get an adapter from Drakware.
The Drakware is the one that my friend mentioned to me, and they're out of
stock at the moment, hence them seeking an alternative (and/or real
devices) :-(

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).

There are a very few SGI vendors around with parts.

Lists some available. These may seem like high prices till you watch an ebay listing go
higher.
