I think you're referring to the poop there. Apparently you're not supposed to use a vacuum cleaner to remove it, because it will simply blow the fine particles everywhere, making things worse. I know that now. I didn't when I cleaned up the garage, but I'm not dead so I guess it wasn't my time yet :)

We keep things like potatoes and vegetables in the garage, and my wife likes to feed the birds in wintertime so there's no lack of seeds either. Big attraction to mice.

The old garage was demolished and the new garage should be mouse proof. We're also getting all-metal cupboards to store food related items. And last (but not least): my SGI's are no longer in the garage :D

So far I've caught 4 mice in the attic and crawl space under the house. None in the garage so far, hopefully the mice are staying out of there (or the cables in the computers are tastier than the cheese in the traps)

New post http://alphaserver2100.blogspot.co.uk/2012/11/new-backplane-arrives.html describing the disappointing news that the new backplane board didn't affect anything, but more detail on the suggested battery fail...

I'm unclear - have you pulled it down to minimums yet? (single processor board, single memory board, base I/O)

yes, I've tried from zero of each of memory and CPU up to trying each in each slot. No joy.

I've got 2 IO boards, 2 backplanes, 3 CPUs (same type) 2 memory boards (same size, but mixing is known to work).

1 of the CPUs in slot0 reports SYSTEM RESET permanently on the OCP. The other two cause the OCP to show nothing at all. This CPU board also shows NO MEM INSTALLED when it is all missing. The other two still show nothing.

the 2nd IO board is known to be missing a capacitor on the rear, but this hasn't lead to any difference in the functions the machine is currently capable of.

Both these IO boards have 2.8V or higher in the RTC clock block.

A 3rd IO board is on it's way. If this doesn't change things, I'll have to source a different OCP board / fan control board / remote ports board. But these are harder to obtain.

Thanks for caring enough to post!

cheers,
Stuart

The third IO board proved successful at getting further: http://alphaserver2100.blogspot.co.uk/2 ... ments.html and a cache of extra components has been located nearby!

Excellent news on all accounts! Hope you enjoy the VT510.

Very cool, and wonderful pictures! It's great to see people taking such care to restore an older system like that (and one that had been so neglected). I had the pleasure of working with an AlphaServer 2000 (4/233) at one time. We nicknamed it "The Beast," because it was built like a tank ("/etc/motd" contained a suitable ASCII art graphic as well). They are definitely sturdy and high quality systems.

Excellent news, Stuart! And now perhaps a chance to update firmware to use those EV5 boards...
