Second earliest known public press release for any commercial transistorized desktop calculator/computer. (recently discovered at

The Museum of TrailingEdge-Technology)

ABOVE: This is the 2nd earliest known -  and recently discovered - public press release for any commercial transistorized desktop calculator /computer (see above). It was discovered through recent advances in early newspaper archival and digitization. This museum's Curator was led to it after conducting several recent interviews with the retired Chief Engineer of WYLE Laboratories at the time, now 90. The museum's Curator was led, initially, to conducting these interviews after chancing upon a mysterious WYLE device and discovering, after conducting an analysis of early WYLE patents, that it is - in fact - the long lost prototype of the WYLE Scientific, which used to be in the personal possession of WYLE's retired Chief Engineer himself. This earliest-known surviving prototype of a commercial transistorized desktop calculator/computer is this month's featured museum piece.

The above clip is the second earliest known public press release of a commercial transistorized desktop calculator/computer. It is dated March 17, 1964 and announces the "all-transistorized"  and "typewriter" sized "WYLE Scientific" and further announces that it bridges a commercial "gap" between mechanical calculators and full-fledged computers. Less than a week after this press release came out there were already several additional - and recently discovered - press announcements for the WYLE Scientific (see this Site). As noted above, the spectacular hand-built and 100% breadboarded prototype for this WYLE Scientific is this month's featured museum piece. 

Compare this WYLE Scientific public press release date with other earliest-known publicly-published press releases (see below). Coincidentally, Sharp's earliest announcement came only one day later than WYLE's. Sources and "clips" may be found this museum's open-archive pages.


Note: Sharp is listed twice because its March 18th, 1964 announcement (which we learned about from the Dentaku Museum) has not been independently verified by our museum and its newspaper of publication is also not presently known to us.

Shown Below: The first public demonstration of the WYLE Scientific Production Model on  April 21, 1964 (not a prototype; taken from the "second batch" of early production) at the Datamation Computer Conference in Washington D.C.. Matthew A. Alexander led the demonstrations for WYLE Laboratories.

COMPARE with other earliest known public demonstrations:

The first public demonstration of the Friden 130 was on May 20, 1964, about a month later, at the Waldorf Astoria Hotel, NY. 

Note: This date is to be differentiated from the date of the secret Friden demonstration of a prototype at a presently unknown location & day in June 1963 with reported non-disclosure agreements. This is quite different from a public announcement and demonstration of a production unit. 

Note: Both Friden, and WYLE's Matthew Alexander, were giving private/secret demonstrations to audiences of industry and trade executives by mid-1963 of their respective pre-production prototypes. 

For the IME 84 the date is April 12, 1964 at the Fiera Di Milano, Italy, nine days earlier than the WYLE Scientific demonstration.

COMPARE with other earliest conventional sales ads:

NOTE: Scientific American, as with most monthly magazines In the United States, Canada and the UK, have cover dates about a month later than the day of release. Hence, the below sales ad for the WYLE Scientific came out in early May 1964, For the IME 84 it is early April 1964 and the Mathatron, February 1964.
