Thread: Talker/80 - New Voice Synthesizer in the Making

    Default

    A first batch has been produced - so far I have a 100% success rate.
    Seems also the Seeed PCBs are of good quality (green ones).

    "Talking Eliza" with the Talker/80:

    A GitHub repository is being populated as well currently - the sources and Gerbers are still missing, but will show up there eventually:

    This is the final Talker/80 demo video. It shows some of the BASIC demo programs that can be found on the talker80.jv3 disk image in the Github repo.

    • Spanish Speaking
    • Advanced Voice Control
    • DECtalk Singing from BASIC
    • Welcome Program
    • Jeff Shrager's "Creative Computing" Eliza with natural sounding DECtalk speech


    All of this runs directly from Level 2 (Misosys) disk BASIC, no driver and no phonemes required. Adding speech to a BASIC program can be very simple. For the Eliza program, for example, I only needed to add some "out 11, asc(c$)" to an already present "character by character" printing routine. 10 Minutes of work.

    That's it for now, folks! Thanks for the interest.

    I'll open another thread when I am going for the Model 3 / Model 4, but probably not before next year.

    Oh, nice! I didn't post it there - maybe they got it from Hackaday

    Update - I just learned from another thread that Talker/80 can also be connected directly to the "Screenprinter Expansion Port" of the Expansion Interface. I was wrong in assuming that WR is not being passed through by the EI. I got missinformation from the book "Hardware Interfacing with the TRS-80" from Uffenbeck. Or there is something else I don't understand. This book states, for example, in Experiment 6 "Memory-Mapped I/O using the 8255" (and in all experiments that use Memory-Based / Mapped IO):

    "This experiment cannot be done on a Model III.... The experiment also cannot be done using the expansion interface and a Model 1 computer. This is because the RD and WR control signals are not enabled on the expansion interface bus (you may want to disconnect the expansion interface temporarily for this experiment)".

    This is wrong. Talker/80 TRS Voice Synthesizer Emulation Mode works perfectly fine if connected directly to the EI Expansion Port (the port in the fron left corner which connects to the FreHD usually).

    So, in that light, the Talker 80's expansion port edge connector passthrough would not have been necessary, but it is still convenient for people that don't have an EI and may want to connect another expansion (e.g., the Quinterface or similar). Then the Model 1 port is not blocked.

    But feel free to connect it to the EI Expansion Port interface instead!

    Mike,

    Very interested in putting one of these together, as I've an original TRS-80 Voice Syth which needs bringing back from the dead, and having a working one to drive me forwards may help

    Any idea on the availability of the gerbers?

    Hi Tarkie,

    the plan is to hear from the first three customers first and check if it worked nicely with their setups. I sold 3 on Ebay last week (within one day, actually!), and they should arrive soon. If there are no unexpected major problems, I am going to put the Gerbers and the Firmware (including sources) online. I will also continue selling 2 or 3 every month on Ebay, but I cannot really produce a lot, and "development cost recovery" is unlikely anyhow, given that the profit per unit is in the 10 $ range for me. So selling them on Ebay is mostly "community service" for folks that can't or don't want to assemble it themselves (or don't have a programmer that can do the rather difficult GAL22V10B's... )

    So, please stay tuned, hopefully by the End of May everything should be online.

    Best,
    Michael
