RE: Cards with word and phrases (NNNs) for HP-67/HP-97
Well, how did HP get the word/abbreviations:
Crd Error to display; by using NNN’s non-normal numbers. Of course a lot more to it than that. Bernhard’s LP HP 29 board has replaced, if desired, all the key codes in program mode with the Alpha equivalents creating characters by ”tricking” the 7 segment display. Cheers, Geoff |
