Hi all, I've got a dead 442, and I was wondering if the schematic is available so I can more easily harvest the components.  I've searched, but only found the N2 DAC schematic package.  I hope the schematics are still extant in some form.

Thanks,
Doug

The 442 was a pre-designed board used to develop the custom software for a later revision, and was not done in-house.  I'm not sure if Neuros is able to provide that or not...

I'll see if I can poke someone and get an official word, though.

Any word about the schematic Chad?

If you guys are prohibited from releasing the actual schematic, would you be able to id components if I give you the silkscreen number or the case marking?  I've been trying to figure out what some of the Qs, Us, and Ds are, and I've had some luck searching various online databases, but one in particular, scattered all over the board at Q1, 5, 6, 7, and 8, with the marking F5A7M has me buffaloed.   I'm fairly certain it ISN'T a bipolar transistor, but that's about it.

Thanks,
Doug
