| Field | One of the First Home Computers circa 1977 |
| Went Obsolete | Early 1990s |
| Made Obsolete By | When Commodore 64s and other 8-bit micros became obsolete. |
| Knowledge Assumed | The concept of centering the adjustment between spots that the sound of the data deteriorates. |
| When useful | Best caseing an adjustment that has a range of operation |
There was sometimes trouble reading programs into the computer that were stored on a audio cassette. A small jewelers Phillips head screwdriver could be inserted into a hole in the top of the cassette player and adjustments made for the best case data transfer by listening and adjusting.
This skill was not limited to Commodore machines, but any which used domestic magnetic audio tape decks to store data on. A related skill came from identifying the type of machine a tape was intended for from the distinctive sounds of the data due to the different mechanisms used by each manufacture to modulate bits into audio streams.
