Connect a 26 pin FDD to your MSX....

[Werner Augusto Roder Kai]

        Hi,

        Today I did connect an external FDD used in laptops to my MSX2. These
drives have only a 26-pin connector. Here goes the cable schematics.
Somebody may put it in a MSX hardware page...

        pin at FDD connector (26)       pin at MSX drive interface conn.(34)    signal
