Dear friends,
I'm recollecting information for an article I will write about the
transition of electro-mechanical calculators to electronic calculators
during the 60's.
I've found that the ANITA from Sumlock Comptometer of England (1963) is
usually regarded as the first electronic calculator [1]. However, recently
I found an article about Heinz Nixdorf of Germany in the LEXICON's History
of Computing (CD-ROM) which indicates that he built several models of
electronic calculators back in 1954 (Models ES12 and ES24).
I haven't been able to obtain more information on these calculators. I
suppose this is because Nixdorf moved soon onto the computers technology
(eventually joining with Siemens).
As a reference, I posted a copy of the Nixdorf article in my web site at
the following address:

Information about the Anita can be found at:

SECTION: VINTAGE CALCULATORS --> ELECTRONIC --> ALBUM --> Anita
Any information on this subject will be appreciated.
Regards,
James Redin
