digital cassette recorder revisited

Because of the extensive interest shown in the "digital cassette recorder" (Elektor — January 1984), not only by owners of Elektor computers, but also by users of "foreign" ones, we felt it appropriate to pass on to you the following practical tips. digital cassette recorder revisited The circuit of the digital cassette recorder described in the January 1984 issue of Elektor was designed primarily for storing data originating in the Junior computer. The circuit will work with other com- puters also, but some of these use such a different tape format that the results are not always satisfactory. If you are one of the sufferers, here are a few hints on how , to adapt the circuit better to the computer and cassette recorder used. In some computers, the hysteresis of the input stages is so long that the data being loaded is not passed correctly to the recorder head. This can be prevented by increasing the value of R6 to 82 k which makes the hysteresis shorter. Furthermore, it is adv...
