Indy is the red or the *blue* one?  I think I have a blue SGI
box... I had problems trying to get it to boot (headless).
Heard the tones on power up but couldn't figure out how to
get a serial console running...  :-(

I also have the VW320 which *seems* to have good audio...
but loud fan(s).

An assortment of SPARC boxen... SS5, SS20, U1, etc. but I
think they all want to run Solaris to make proper use of
their audio hardware.

And, a GUS MAX and a GUS PnP which are good for *playing*
sounds but no idea how good they are at recording.

Plus laptops with dubious "consumerish" audio...  :-(

Anything else is not intended for use with audio (servers)

Yeah, get a SPARK GAP and drive it with a couple of KV... :>

I suspect its going to be the sort of thing that I "do it"
and then, after the fact (after processing all of the diphones,
etc.), discover that it's not good enough (for any of a variety
of reasons, many of which are probably NOT related to the
hardware/software but, rather, failing to keep a consistent
"tone of voice" when recording the samples).  Unfortunately,
I am not big on patience for these sorts of things.  :-(
And, if I impose on other people to undertake the same
process (as they may have "better" voices), then it becomes
a big imposition if you have to tell them you need a "do over".
Hence the push to figure out what I need "up front".
