The folks with TI-99/4A and arcade games have got more on the TMS5200 / 5220C than I can shake a stick at.

SpeechViewer Origins (from Great Hierophant)

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.

Speech Control Assembly

Front View

Two 1/4" headset jacks, microphone jack (?), volume rheostat.

Bottom View

I saw a Photoshopped picture of one of these in an 8530 bay. Note the tabs, they might mate with a slide for the 8530, looks like a floppy-type slide (intermittent tabs).
