This model of a CPU card (code 6735-556-02) is one of the most versatiles ones. Unlike the previous solutions, this card operates with a few elegant, modern graphic displays. You will find it in the following machines: Canto, Concerto, Festival, Melodia, Opera, Rock, Samba and Tango.
Typical problems:
- doesn't start
- spinning multiple motors at a time
- doesn't detect a tray
- missing info on display
- freezes after photocell test
And there's an untypical problem worth mentioning. It may happen, that user will attach the UpKey to the keyboard port. It quite often results in a severe malfunction (burns plenty of integrated circuits). In such case, please contact us first.
