Re: SGI Indigo Power Supply Pinout?

[devin davison via cctalk]

I Have an indigo that has not gotten much use aside from when i first
picked it up. It has the bigger power supply as well and is maxed out on
memory. As a last resort, I could sell you my machine. It boots, I had
rigged a peice of jumper wire to the battery to overcome a flat battery, i
did not want to attempt desoldering the battery on board. I have been
focusing less on the smaller workstations like the indigo and octane and
have been using my onyx and crimson, so I am looking to get rid of the
smaller workstations.

What's going to happen to all the weird stuff?



It will magicly blend back into the state ...
When you think about it, there has not been much new weird stuff since 
the 1980's. I am testing a 20 bit cpu (2901 design) in a DE1 FPGA 
development system, and plan to use real hardware later this year

but that is only 1 new weird item for 2018.

PS: Most of my development work had been fucked up by windows,
several  files had been secretly rolled back when it felt needed
to install new drivers, could not find them, crash and restore
the old crap, but only after a bootup.

SGI Indigo Power Supply Pinout?

[Ethan via cctalk]

Howdy,

 Working on fixing an old SGI Indigo of mine in prep for VCF East.

 The issue is once any sort of IRIX kernel is running, it craps out 
WARNING: Power Failure Detected at a high rate.


 The SGI Indigo and a few other similar models could push out 
that error on the local console and perhaps network inbetween the time 
that AC power was lost going into the power supply and the power supply 
had discharged enough for system to die. Pretty impressive and strange! 
I was amazed when I first noticed it, of course now it has come back to 
haunt me.


 I have replaced some of the electrolytic caps in the power supply.

 But in the spirit of troubleshooting, does anyone have any sort of 
schematics or documentation on the power supply, or the midplane?


 This is a R4000 Indigo and has the higher output power supply to support 
bigger CPU and graphics.


 In the meantime I'm working to document what I can about the power 
connector and will publish, but I can only get so far without other 
insight.


 Thanks

P112

[Bill Gunshannon via cctalk]

It's not really Classic Hardware, but it does run some pretty classic

OSes.  Anybody here working with the P112?  I have had a couple for

ages but never had time to play with them.  I see them now as a

possible way to manipulate floppies (including 8") from classic systems

so I decided to give it a try.  Problem is, it won't boot anything.  Not the

disk that came with it and none of the images I got off the web.


Anybody here know anything about them?

If anybody has one or two of these aftermarket RL disk emulators that
use ST-506's they want to get rid of I would love to have a couple. I still
have ST-506's and would love to try these out as I have never seen one
in use.

The only ones I can find now are the ones you mention.   Yes, I too can't find
my notes on the second one, whatever it is/was.   I was *sure* that someone
had made a Qbus emulator that used SD cards, but I simply can't find any mention
of it now.

Right now, it looks like Reinhard Heuberger's board is the best bet.   I haven't
checked with him yet to see if boards or kits are still available.   If I could
find a working TDL-12 I would jump on it in an instant.   All the older ones
(Dilog, etc.) appear to use ST-506 type drives, which introduces its own set of
problems.

Here's the newsletter Weirdstuff sent to all their subscribers:
---
WeirdStuff Warehouse Newsletter

April 6, 2018

To Weirdstuff Customers,

Sadly, after 32 years in business, Weirdstuff Warehouse will be closing
its doors as of April 9, 2018. If you have been following the real
estate news for Sunnyvale you know that Google purchased a large amount
of real estate in the area including the building we have been leasing
for the past 22 years. We have been asked to vacate the building as
soon as possible, and in order to accomplish that task we are selling
our inventory and many of our assets to Outback Equipment of Morgan
Hill. The transfer of inventory and assets will take place on April 9,
2018; at that time Weirdstuff Warehouse will cease to do business.

Even though Weirdstuff is closing we will retain ownership of the
Corporation, trademark, and domain names. We hope to handle these
entities and wind down the corporation before year end.

Many of you have been loyal customers for many years, and we have
enjoyed working with you. We thank you for your loyalty and business.

For more information, check out our website after Monday, April 9, 2018.

I spent most of yesterday (Friday) hanging out at Weirdstuff. NBC News
interviewed WS management and myself about the closing. NBC showed up
because of the "trend" of Bay Area tweets about the closure. Needless
to say, the WS store was packed with sad faces about the closing. Not
one good word about Google, who is buying up all the land they can and
wiping out small businesses with disregard.
