As much as I'd like to sell you my old TNC220....
A few thoughts;
- Wondering why you specifically want a TNC..
- If the PC has a sound interface consider using a "soundmodem" driver.
ie drive the radio from the speaker and listen on the line input. (with
suitable isolation and level control.
- Use the parallel or serial port to drive a Baycom style modem. ie a
single chip and XTAL from memory. (eg

Then again you have probably heard all these arguments before!
