2 3.5mm jhackl sockets (what you'd call mini phone jacks :-)) on it,
one labelled 'microphone input', the other 'speaker output'. It
contains a couple of 324 quad op-amps, an LM380 audio amplifier, a
small-ish PROM (256 bytes, I think), TTL and 4000 series CMOS logic,
and a MC3418 (is that some kind of Codec?)
I believe I have this card but never really found out much about it.
Huristics Model 20A-1. Possibly sound/voice input. One
3.5mm jack
socket (microphone?), 2 324 quad op-amps, 2 339 quad comparators, a
2708 EPROM, and a little TTL logic.
Sounds familiar. I know I do have something from Huristics...a speech
synthesizer.

Some more information from the "Apple II FAQ":
According to the MCI Supertalker manual, the card plugs into a Slot and lets
you digitize human speech and store it on diskettes. Supertalker can replay
the stored digitized speech via the speaker supplied with the system.
Supertalker software includes the Vocal Preparation System (VPS) for
developing phrase diskettes. A phrase diskette can have numerous tables
containing words, phrases, and complete sentences.
Quality of recorded data is dependent on the selected digitizing rate which
can range from 512 bytes/sec (lowest) up to 4096 bytes/sec (best). Playback
volume has four software selectable levels.

Argh!. Whatever software should have come with this board is long
since lost (I never had it). Ditto the speaker, but that's no problem
at all...

MC3418 is a "Continuously variable slope Delta Modulator / demodulator"
"Providing a simplified approach to digital speech encoding / decoding ..."

there's the PDF of the datasheet for it.
and here's a URL for a bunch of datasheets on common IC's used in arcade
machines...
