Hi, all! I'm kinda novice around here... So can't get at once if the topic will be interesting to you chaps. In my school days I used to work with programmable calculators (Soviet ones - .ua was part of SU that days). So if smb finds the topic interesting I can try to recollect all I know about 'em and post right to the group. And I can assume they could be called classic 'cause the last model of this "Elektronika MK" series was issued ~11 years ago. So, if find it worth typing please mail me to andy(a)topaz.kiev.ua -andy
