I really would like to have a simple re-implementation of ye olde TNC-2s that had a small eprom and a kiss mode TNC with a fricking BBS on ax-25 that worked like a charm. They existed I believe around 1988-1990ish.
I mean, yes, this cable works with direwolf, but then I need to have a full linux system running, which I could do without for the purpose of an emergency comms system.
I have one of these in the garage. I think they're 6502-based with the OS on EPROM, or at least that's what I vaguely recall from last time I had mine opened-up about 20 years ago. I can dump the ROM if it'd help.

I just found https://github.com/cheponis/KISS-TNC2, but I think this is just the KISS mode, not the AX25 stuff.
I found https://www.ir3ip.net/iw3fqg/doc/wa8ded.htm which I think describes the TNC2S software I was running many years ago.
Any other pointers would be great.

Many thanks for the offer! I have a few old ones, too. I'm sure I have seen .bin files with dumps. Maybe here: https://home.snafu.de/wahlm/tfdownload.html
There was some bad blood between Wa8DED and NORDLINK/TheNET about copying, maybe best to contact WA8DED directly, or the NORDLINK guys.

Then again, maybe it would be better to jump on the LoRA bandwagon and make something similar work with meshtastic: https://github.com/TheCommsChannel/TC2-BBS-mesh
Likely a Zilog Z-80 CPU with 28C256 eeprom.
