Ketron SD & USB reader

Has anyone purchased and used the SD/USB reader for Ketron's older keyboards? How does it work? and from the instruction manual, if a older ketron has a hard drive, im guessing the hard drive is removed or does it still remain?

Thanks,

I've used in my Sd1 many years ago..Hard drive was removed..Pcmcia card needed..

There was some os problems when i used but, many os and firmware released after i sold

İ can say; it is usefull...
