Hope I haven't poked > a balloon with a pin here... No, i find the alternative of a 1394 device completely acceptable, too. But how much cheaper would it be? I suppose the logic for talking to the 1394 bus [?? i don't know anything about firewire, except for 1. serial, 2. faster than USB] can be put into a FPGA again, right? For the sake of an example, let's choose a stereo full duplex device with 48khz only samplerate, and with medium to good quality AD/DA's. So we got like 15-30 bucks for the DA/AD's. What's the rest? How expensive is the FPGA to control all this? What else is needed? Ok, a case mustn't be pretty, so i suppose anything will do -> 2-3$ :) Flo
