I would be connecting it to a first generation VIC-20. It is not exactly a D/A/A/D converter. Because the 300 baud modem uses only two frequencies (one to indicate a 0-bit and one for a 1-bit) it: a) only has two filters that detect the presence of one of the two frequencies (+/- filter width) on the receiving side. The result is signaled to the computer as one bit - on or off. b) only has two frequency generators, one for each of the two used frequencies. The computer switches the frequency by one output bit. So I guess using it as a soundcard is bit off in this case... Andre -- Email address may be invalid.
