as tu démonté la machine pour voir si y'avait pas un nid de guèpe ou trop de poussière ?

Demander à Kris s'il a ouvert la bête pour vérifier s'il n'y avait pas de poussière, c'est d'un drôle …
Je m'en suis pété la rate.

To the right is a 1,44 megabyte 3.5" disc drive and a connector for another, external, disc drive using a Centronics style connector. A common defect with the ALT is a malfunctioning 3.5" disc drive.

And the Teac FS-235HF drive only has one cable: the power is supplied through (a few of) the ground connections of the data cable. Ideally for a portable, where space is always an issue.

But replacing a defective disc drive by a standard model is a problem because these all have two cables: a separate power connection and a data cable.When you use a standard 3.5" 1,44 HD drive you will need to cut the power leads from the data cable of the ALT. See the schedule on the left (you can enlarge the size of the picture).

To supply the replacement disc drive with power, you can use the wires cut from the original ALT connection. Or, alternatively, you can use the power supply of the ALT directly.
See the layout on the left side (you can enlarge the picture). This schedule can also serve a purpose when you want to connect a new, replacement, battery: you would need to make a new battery because the original batteries are no longer supplied.

This could be an expensive affair, when you put the job to one of those firms specialised in batteries. But, on the other hand, a new battery will be considerably lighter and more powerful (longer lasting) than the original battery with, by now, out-dated technology.


On the right you will find another scan from the technical service manual showing, again, the connection and wiring of the internal 3.5" disc drive.

Plus the wiring of the connector for the external disc drive, with the 36-pin Centronics-style connector shown in the photograph above.
