Google for "covox schematics". Right, I know, thats exactly what I made. I just realized I never had any diodes in the thing, just resistors. It was just a resistor ladder. You aren't getting 8-bit resolution out of that, though, and it is not a PCM DAC. -- Chris Dillon - cdillon(at)wolves.k12.mo.us FreeBSD: The fastest and most stable server OS on the planet - Available for IA32 (Intel x86) and Alpha architectures - IA64, PowerPC, UltraSPARC, ARM, and S/390 under development - http://www.freebsd.org No trees were harmed in the composition of this message, although some electrons were mildly inconvenienced.
