found it: first speech synthesizer (at least, for S-100 systems)

Some years back, I was asking if anyone had information about the speech
developed for the Altair 8080 by Wirt Atmar of AICS (in New Mexico).
Most places on the web claimed the Computalker was first, given the date as
1976 or 1977.
(Earlier speech synthesizes existed, but they were external boxes that one
or were standalone (often with a large/weird keyboard).)
Today, I stumbled over a fairly bad OCR of Byte magazine from August, 1976
It has two articles about speech synthesizers for S-100 bus systems.
The first is by the Computalker people, who say:
At the time this article
goes to press, a synthesizer
module incorporating several
detail refinements and im-
provements over the circuits
of this article is being de-
veloped by the author and
A detailed user's
guide will be supplied with the
Note the future tense!
The second is by Wirt Atmar, whose product *was already shipping*.
Near the end of his Byte article, Wirt lists currently available products:
At the present time, two speech synthesizers
are both commercially available and affordable by
One is the Votrax produced by:
Vocal Interface Division
Federal Screw Works
500 Stephenson Dr
Troy Ml 48084
Price, approximately $2,000
Interfacing: Parallel or Serial (RS-232)
The second is the Model 1000 manufactured by:
Ai Cybernetic Systems
PO Box 4691
University Park NM 88003
Wirt had told me (twenty years ago or so) that he thought his was the first
for microcomputers (e.g., a user installed card, not an external box).
Now, I'm sure ... but it was realllly close!
Wirt demonstrated his product at the earlier MITS World Altair Computer
tion, where it won first prize.
He advertised it poorly/infrequently, since it was mostly a side business.
And, that shows, since history doesn't remember it.
