This looks indeed very much like an Indy, less a Challenge S. A Challenge S
usually has an additional WD33C95 SCSI controller as well as an extra
Ethernet. Also, afaik the keyboard controller has been removed from
the Challenge. So your machine looks like an Indy with the GFX removed.

Too bad. Guess for now I'll just use that ``CMN B006S'' ...

Sorry, offhand I don't know which one is working. Most of these

I think it's called rumour ;-)

Tandem has a very interesting program of HA machines and software. They
have more or less the only UNIX systems that guarantee like 99.99999%

220 everywhere here. But I fear that I'll soon need a 400V connector
for my next machine ...
