Hi Tom,

Neat find!

One thing you can do is use the fact that Russian written language is
very similar to the way it is spoken.  There is not all the weirdness
that we have in English such as the various ways words ending in
"ough" can be pronounced.

I believe you wil be able to get quite far by using your
Russian-English dictionary, as you mention.

If you can see into the power supply you may be able to deduce what it
takes.  Or maybe not.  

Are you sure it is not an Elbrus 2K ?
