I don't believe I brought this up here before. I'm looking into TDD emulation by a Mac. I've got a couple of leads on making a Mac do Baudot, maybe even at 45.45 baud, but I do need to provide a modem. I have a few options here. I have a couple of old Pennywhistle 103 modems that as I recall should be suitable for conversion. Does anyone have the documentation for these? I haven't located whatever I might have. A reference to the original Popular Electronics article would be useful, but there was a more complete package available, that I had at one time, that would be more useful. Also, references to old construction articles for 300 baud modems, preferably using the XR2206 and XR2211, preferably known good are desirable. I have the EXAR app notes. Comments on their accuracy are welcome. And of course, any other information you have about such things above the basics would be much appreciated. I've references the previous articles on TDD's that came across here, and they were most useful. Thanks, and 73, doug faunt@cisco.com PS: In digging into my archives, I came across a set of the "Inside Ma Bell" articles from 73 Magazine. df
