TashThird: TelePort A300 ADB Modem Emulator

[tashtari]

Just a little project, I'm not sure anyone's going to get excited about this one. Introducing... TashThird! (it's a third serial port, get it?)


Elevator Pitch

It's as faithful an implementation of the Global Village TelePort A300 modem protocol as I can make using what I've found out about the protocol (notes here), linking it to a serial port with flow control lines, capable of a blistering 2400 baud...


Project Status

Nascent but tested and working.


Caveats

Emulation is just about as good as it needs to be and no better. I'll improve it if I discover more about the protocol.


What's Next

A PCB, maybe, if anyone's interested. It'd be neat to make this into a cable with the PCB fitting inside a DE-9 shell...

Just picture a breadboard that looks like a bird's nest. =)

I think I know what to expect :

My Z80 probably needs turning into a PCB at some point, but I got distracted by other projects.
