Addiators and other slide adders  is an alphabetical catalogue.

In this PDF-file (Version  2025) you can find more than 600 different addiator-pictures  and also a spreadsheet with the characteristics of all these slide adders.

Most of the pictures in this non-commercial catalogue have been taken from www.rechnerlexikon.de

You can find the owners of the pictures in the spreadsheet-column PICTURE. 

The rights of these pictures belong to these owners.

More than a hundred pictures are from my own collection.

Thanks to Friedrich Diestelkamp  for his advice.

Thanks to Edgar Elsen, who give me many pictures from the "Diestelkamp-collection"

Thanks to all, who send me pictures.

 Do you have pictures to complete this catalogue or do you see an error, please send me a mail.
