Thread: IBM 27F4943XM Speech talk Adapter

  1. #1

    Cool IBM 27F4943XM Speech talk Adapter

    Seeing any information on the
    IBM 27F4943XM Speech talk Adapter.

    The board uses a mouse like connector, information
    on the web seems to be scarce.

    People selling this card mistaken it for a Mouse Card.

    Interesting. What software would utilize this? Proprietary IBM software?

    It's the IBM PS/2 Speech Adapter card, capable of LPC and CVSD-format playback via the TI TMS5220C and Motorola MC3418 chips, respectively. The card is basically unusable without the external speaker/headphone box that attaches to the mini-DIN port.

    Here is an auction for the complete card/speaker pairing:

    There's been some recent discussion about the Speech Adapter (PS/2 and PCjr) on Mike Brutman's forum:

    Here is a list of (mostly educational) software purportedly compatible with the Speech Adapter:

    Other products providing Speech Adapter compatibility include IBM's ACPA and Audiovation cards, Digispeech's DS201A and DS301A (and possibly the DS311), and DoubleTalk's PC/LT products.

    The PS/2 Speech Adapter is derived from the PCjr. Speech Attachment and uses the same TI TMS5220C/TSP5220C chip. Since it uses the ISA bus, and the PCjr.'s bus is mostly the same, I wonder if the card would work with the older software without a TSR program. The Digispeech devices require a TSR loaded for IBM Speech compatibility, and it may not work with all programs.

    It's not just Digispeech - all of the mentioned devices claiming Speech Adapter compatibility use a similar, BIOS-emulating TSR.

    Here are a few additional titles that support the Speech Adapter:

    First Byte / Zugware
    Zug's Adventures on Eco Island
    Zug's Dinosaur World
    Zug's Race Through Space
    Zug's Spelling Adventures

    The design of the external module for the Speech Adapter appears to allow for sliding and snapping it into one of the front module bays of a Model 30 or similar, to then be plugged into the internal mini-DIN socket found only on the earlier SA cards. This "internal" configuration doesn't appear to be advertised or mentioned anywhere, inexplicably, but would be interesting to see.

    So, with apologies to the original image owner and to Photoshop users the world over, here's an "artist's rendition" of what the Model 30 might look like with the Speech Adapter's module internally installed...

    Street Electronics' Echo PCII (not the "PC2") can be added to the list.

    That's a ridiculous amount of hardware compatibility for a device with such limited software support. I think this puts the IBM Speech Adapter into computing "standards" territory.
