very interesting :-)
It would be nice to know how much better the price/performance ratio
of your solution is compared to the $4000 hardware.
would this hardware be enough:
- Dual Celeron with Abit Motherboad
- 64MB of RAM
- cheap gfx card (or leave it out completely)
- cheap hd
- Dig96
I don't know how much the Digi96 costs, but do you think
you can achieve a $1000-$2000 price ?
Just like I predicted ... some "standalone audio equipement" will sooner or
later run Linux. (because of the excellent price/performance ratio)
:-)
Benno.
