Quoted message said:Aha! Googling for avocet + cyclocomputer + 1983 doesn't turn up
anything useful, but avocet + cyclcomputer + 1984 turns up a mention
of an Avocet C-10 "that came out around 1984":

Quoted message said:That thread also includes a claim that electronic stuff was already

Fumbling with the U.S. Patent office yields a 1977 filing and 1979
patent issue for an electronic bicycle speedometer that cleverly uses
the trigger of the bigger blink of the valve stem interrupting a light
beam:

Some fellow recently wrote a letter to VeloNews (june 11 issue, I
think) claiming to have invented and sold something that sounds very
similar to this device. He said the name of it was "Digi-Tac" and
that he starting selling it in 1974. his letter was an attempt to
refute the VeloNews claim that the "Pacer 2000" was the first cycle
computer. Velonews printed his letter and even included a picture of
a "Digi-Tac" device mounted on a bike and also what appears to be some
sort of advertising flyer for the unit. The guy claims to have
developed this device as part of a mech. engineering course that he
was taking. Seems plausible enough to me. So, 1974 then?
Dear VF,
So far, I've found nothing about Digi-Tac on the internet, but the
VeloNews forum had this post:
"Switched from that [Huret mechanical odometer] to the Pacer 2000
which was as big as a small TV. Then the Avocet 20 came out and
revolutionized the market."
http://www.velonews.com/phorum3/read.php?f=2&i=219612&t=219600#reply_219612
I had a vague memory of huge sensor rings being mentioned on RBT, and
"pacer 2000" leads to it. Andrew Muzi has two pictures up at Yellow
Jersey, the upper photo being a Cateye CC-1000 and the lower photo
being a Veltec Pacer 2000:
http://www.yellowjersey.org/photosfromthepast/OLDCOMP.JPG
Here's Andrew's post, where he cheerfully explains the details to a
particularly clueless reader:
http://groups.google.com/group/rec.bicycles.tech/msg/06af8e152631243f
The Pacer 2000 is mentioned in US Patent 4636769 (which is for a later
bike computer):
"Pacer 2000: Advertisement on "Bicycling" Magazine of Jul. 1979, p.
2-VSCL"
patft.uspto.govnph ParserOpen ↗
Another patent, 4435983, mentions the same ad:
"Pacer 2000 Advertisement p. 2, Jul. 1979, Bicycling.. "
patft.uspto.govnph ParserOpen ↗
So the Pacer 2000 was advertised as far back as July, 1979.
US Patent 4456277 for a tricycle filed July 12, 1982 mentions the
Pacer 2000 and also the Entex bike computer (not mentioned previously
in this thread):
"To observe cycle operation and rider condition, I prefer to use a
monitor 18 having heart rate sensors on the handlebars and a magnetic
pickup on one of the wheels. Commercially available monitors include
the Pacer 2000 and the Entex bike computer."
http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=4456277.PN.&OS=PN/4456277&RS=PN/4456277
Aha! The Entex was available by 1981 and had accessories for cadence
and heart rate! Wonderful details here:
http://www.handheldmuseum.com/Entex/BikeComputer.htm
Entex seems to have been a company that made plastic models and
hand-held computer games up to 1980.
