Re: SGI Indigo, Warning: Power Failure Detected scrolling forever on install

Is it possible that the power supply has failed MOVs, causing it to pull the line voltage low, then detecting a power failure as a result?
MOVs wear out after absorbing repeated spikes.

Re: Indy memory problem - runs with 4x32, but not with 8x32

That's a good point. You can run the hardware confidence test by typing "boot stand/ide" at the PROM console prompt.

My suspicion is that you do not have a large enough swap partition if your kernel is configured to use hard swap space.

Re: My FPGA based Lisp Machine project

Hi geo :)

I don't read Japanese (despite what I said) but maybe there is information you can use:
http://www.nue.org/nue/tao/bitao/new-tao-elis.html

I don't know if the research labs that did them are still around (very surprising if so), but you might be able to contact someone who knows about it.

Re: My FPGA based Lisp Machine project

I don't know, but the information may be out there. I expect it was the standard expert-system-shell type application mix (airline schedulers were mentioned). That makes sense, because airlines were some of the last major users of lisp machines. SwissAir bought hundreds of TI Explorers after they we...

Re: CPU problem - SGI Indy

Pulling PGA packages without bending the pins is rather hard without special extractor tools.
Straightening the pins is no cakewalk either, but there is an excellent tool for that, too.

Re: which was the best X11(R4)-terminal?

InfoWorld wasn't necessarily known for its editorial accuracy. Cyan-Magenta-Blue indeed.
I was also surprised by the X-Window printer concept: complete madness!

Re: My FPGA based Lisp Machine project

There are certainly stories of people working themselves to death in Japan, but I think it gets overplayed in Western media. Japanese is also one of the easier languages in the world to learn. geo: did you know there were Lisp machines designed and built in Japan? http://museum.ipsj.or.jp/en/heritag...

Hmm, weird. I always thought they were PReP/CHRP machines.

Re: 7 BeBoxen on eBay

The OS was basically the same, but the BeBox had some special peripherals ("GeekPort") and always booted directly from OpenFirmware. On The PowerMac, you could boot from a launcher application on the Mac side, like you could for MkLinux.

Re: Indigo Keyboard/Mouse converter

Almost certainly you can use just one MCU. It isn't as if translating keycodes takes many computrons. Depending on power requirements the same MCU can also be used to drive a switching voltage converter.
