Re: [Fairlight-CMI] Floppy drive issues

2013-03-08 by Harald Feldmann

Hi David,

Did you check whether the drives are 50 Hz models ?
Both drives defect sounds not too likely.
Could also be smear on the heads, oxidization or dust or a broken center
pressure ring ?

Are all the cards in the right slot ?

Regards,
Harald
