You'd be surprised. I have one of the oldest TNCs in the world (pre-TAPR
:-) and I can still find parts for it - and for many old radios in that era
- eBay is a very useful tool - good luck!
BTW - what you may be looking for is an MC145406.

Rob,
You might find difficulty sourcing that smoke. That particular smoke
has been EOL for quite some time.

Hello All,
I recently had a power supply problem and it has let the smoke out of
my PacComm TNC-320 packet modem.
While I have the manual, I do not have a circuit diagram and only
have a partial id on one of the cooked ICs U17.
The partial number is MC xxxxx06P (I think) and is on the main board
across the RS-232 D9 connector circuit.
Could you check your circuit diagram, parts list or slide off the
cover and have a look and let me know what the U17 IC is please?
Many Thanks
Rob
