Re: SGI Indigo keyboard / mouse / converter wanted

[Andrew Diller via cctalk]

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.

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.


You need to 
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) :-(

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.

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.

I think the Wombat adapter would work (?)

SGI Indigo keyboard / mouse / converter wanted

[Jules Richardson via cctalk]

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
