The Solaris CDs used to have /usr/demo/DIALBOX (and BUTTONBOX) with source code. I think it was meant for xview though so you'd need to pick out the useful bits (if any). Richard Sheppard

SGI Indigo Power Supply Pinout?

by ethan＠757.org

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 -- : Ethan O'Toole

Amust Executive up for auction

by trash80＠internode.on.net

Not sure if anyone in the Melbourne (Victoria, Australia) might be interested in this. I only just found about it from a friend of mine in Melbourne. The very famous (well famous here anyway) Kerleys Auction (http://www.kerleys.net.au) in Geelong have listed an Amust Executive computer in tomorrows (10 April) auction. http://www.kerleys.net.au/current-auction Its Lot 177 in the tomorrow's catalogue: http://www.kerleys.net.au/images/auctions/10-04-2018/CAT10-04-2018.PDF >From the only photo it looks in reasonably good condition. http://www.kerleys.net.au/images/auctions/10-04-2018/1-280/DSCN3459.JPG I believe Kerleys will take bids before the auction but not sure of terms - number is (03) 5223 1533 It's not something I'd like in my collection but may interest another Australian collector.

I have now tried this and am not having success. I have a traffic light on the serial cable and I know I'm getting chars out of the host and that I don't have TxD and RxD swapped. I'm not seeing any responses from the dial box and the python script does all the initialization and just sits there. Frobbing the knobs produces no blinks on the traffic light and no text from the script. So... I'm digging deeper and I've found two references to some code >from around 2002 that can interact with dialboxes, but the sites are no longer up and the internet archive did not save the binary archive files. I'm asking here in the hope that someone saved copies 10+ years ago when these files were still being served... In the following thread on the ccp4bb list, there is a mention of these archives... [ in http://www.ysbl.york.ac.uk/ccp4bb/2003/msg00204.html ] "I'm using SGI dialbox (Part# DLS80-1022) with XFree86 4.0.x under linux, with modified version of the Joe Krahn's dialbox driver. You can get the modified version from http://www.biochem.s.u-tokyo.ac.jp/~ishitani/dialbox/dialbox-new.tar.gz and the original version from http://www.geocities.com/joekrahn/ " So I'm looking for: dialbox-new.tar.gz dialbox.tgz dials.c Apparently Joe Krahn hasn't done much with Open Source in 15 years because looking for him has not been fruitful. Thanks for any bits! -ethan

SGI Indy power supply: identify this diode?

by pete＠dunnington.plus.com

After a recent power cut and a series of glitches as the power was restored, one of my Indys suffered a PSU failure. It's a Sony APS-81 171W unit, SGI P/N 060-0008-001. I've found half a dozen damaged parts, and I've identified a 150R 1W metal film resistor (R135), two trannies (Q105, a 2SC4304 and Q106, a 2SC2785) and a couple of small diodes. One of them (D116) appears to be a 6.2b2 (6.2V 1/2W) zener. The other one I'm not sure about. On the PCB it's labelled D113, and it's adjacent to the 2SC2785. It's very small, with a green band at the cathode end, and the legend "4B" in green - photos at https://www.flickr.com/photos/pnt103/albums/72157667056183978 Oddly, another Sony PSU I looked at had a diode there that looked identical except it's marked "4A". I have an idea what it might be but if anyone actually knows what family or type/value this is, I'd be grateful for any insight. -- Pete Pete Turnbull
