[Coladam] Transferring ADAM tape/disk images to physical media

There were plans done by a few people (in newsletters) for converting the AdamLink modem into a fixed speed 9600 baud serial port, so that is certainly within reach.

Did the adamlink modem use an UART or ACIA chip connected to a single chip 300 Baud modem? The TRS-80 CoCo Direct Connect Modem Pak was such a beast and I took the modem chip out and added level converters and turned it into a serial port (based on information from Marty Goodman). If the Adamlink modem is designed like that it could theoretically be converted into a serial port.
