Correction
I am very sorry to inform our readers that the footnote on page 121 of the paper
Mealy-automata in which the output-equivalence is a congruence
I. Babcsanyi A. Nagy
appeared in Volume 11 Number 3 of Acta Cybernetica, was edited by mistake, and it actually belongs to another paper. The correct footnote to the above mentioned paper is "This work was supported by the Hungarian National Foundation for Scientific Research (OTKA) grant No. 7608." I apologize both the authors and the readers.
