    Personally, I only own a Model 1 and a Model 4. Model 4 I will support sooner or later, no doubt about it.
    Model III support should be a subset of Model 4. As far as I know the only difference is that Model 3 will access the device more slowly.

    If you're feeling especially generous, route the cassette relay signal to the device along with the audio. When the relay is activated you can turn off speaker output of the cassette audio. It'd be a small convenience to anyone who decides to CSAVE.

    Or maybe they'll just have to learn to turn off the speaker or something.

    Yes, little on/off switch for speaker I am OK with. Have to be mindful of the costs... I need to change the audio socket. Currently, works with stereo plug only. Mono plug doesn't get through. Most cassette audio cables will have a mono plug (like the one I got from Ian M.). Well, next PCB revision...

    In the meantime, here is a new video, showing the first PCB version in action, and that the expansion port passthrough via EI works:

    Project update: TRS Voice Synthesizer emulation, first steps:

    https://youtu.be/rNow4joSyGI

    Still some fine tuning required, but the overall scheme of things is working.

    Next steps: refine TRS Voice Synthesizer timing and single phoneme utterances, then VS100 emulation.

    I have finished the PCB design - this is the 2nd prototype, PCB revision 3 (not counting the breadboard version).
    Pictures attached.

    The firmware is almost final by now, but still some work required, especially wrt. VS100 emulation.

    Features:

    - DECtalk / EPSON speech: natural TTS engine for English and Spanish, no phonemes required. DECtalk singing, different voices, etc.
    - easy to program from BASIC: port 11, or "print @992,..." method
    - 3 LEDs: Mode, Data In, Speaking
    - TRS Voice Synth emulation
    - partial VS100 Voice Synth emulation (no pitch control so far)
    - expansion port pass through connector
    - compatible with EI and FreHD and floppy drives
    - audio mixer for sound and speech
    - 2 pots / trimmers for input mix
    - optional speaker and amp
    - 1 pot / trimmer for amp audio volume
    - goodies (database of HAL9000 quotes)
    - intelligent firmware (e.g., firmware modes can be changed via software / control bytes)
    - reset button for device
    - speaking / ready signal available via INP(11) for VS100 and DECtalk / EPSON modes.
    - handy DIP switch for initial / startup mode selection, but can be changed via software control byte anyhow

    Price: 80.80 $ plus Shipping. Speaker and audio amp option is 15 $ extra. 5V wall wart with positive tip polarity required; not included in the price.

    Will ship in June (depending on Seeed).

    Allright, the VS 100 Emulation is working by now - check out the VS48 and VSDEMO.BAS program:

    I have used an old PC-speaker instead of the little loudspeaker this time for demo of the Talker/80 amplifier option (note that there is no amplifier in the PC speaker). The sound quality is quite decent with a larger speaker such as the one used here.

    Some folks asked me for more details, also regarding the firmware sources.
    Sources will be made available on Github soon, but not quite yet.
    In the meantime:

    I am looking for 2 volunteers that would be willing to test the Talker/80 with their systems.
    If you are interested, please PM me.

    You need to have a Model 1 with Expansion Interface. And preferably at least 32 KBs so you can run the VS100 software. And disk drive etc. and knowledge how to run the programs etc.
