Attacking this rulesetting method, Foster2 demonstrated the scientific irrationality of the classification by focusing on the economic reality revealed in the bookkeeping system. Foster emphasized a pedagogical focus that correlated with the logic of economic activity rat...
The function of the front panel keys is reproduced by either a contact closure or an asserted low (0V) logic state on these inputs. This low state must be held continuously for at least 25 milliseconds. After this, the input must be allowed to pull high for at least 105 milliseconds ...
