I just bought a PowerMac 7200 and discovered that the usual microphone was
not supplied.
Then I borrowed one from a friend, but still I could not record (I tried
Simpletext and Audioshop).
Does anyone know if there is a built-in microphone in my PowerMac? If yes,
where is it?

Here is the sound hardware info about my mac (from Techtool):
Sound:
     Hardware has Stereo Capability
     Stereo Mixing on External Speaker
     Sound I/O Manager Present
     Built-in Input Hardware Present
     Input Device Available
     Built-in Simultaneous Play & Record
     Can Play and Record 16-bit Samples
     Can Record Stereo
     Input Port Requires Line Level
     Play Double Buffer
     Multiple Channel Support
     16-bit Audio Data Supported

I tried to use CoolTalk (with no success), but the readme file says that I
should have a PlainTalk microphone. My microphone is just a simple plastic
round-shaped thing that was supplied with another PowerMac. I think it is
stereo.
Is that a PlainTalk microphone?
I also tried to record from SimpleText with no success.

If I go in the Control Panel, Sound, I can set the input source as either
External Microphone or Internal CD.

I am sure that the microphone is plugged in the right port.

Can anybody email me some hint? Do I need a new microphone or some setting
is wrong?

Thanks,
Max
