Hi Jaaf,

This is your friend Bob Gelman writing. I spoke with a Yamaha Technician (at Yamaha USA) about these drives. I know people have NOT had success just putting in a substitute floppy drive that "fit" (same voltage, pins, etc.). The tech told me that the drivers of the PSR were designed for that EXACT SPECIFIC FLOPPY DRIVE that you have in your PSR. If you can find that exact drive it will work, otherwise probably not.

Given the cost of buying a drive from Yamaha, here's what I'd do. Try to find the EXACT drive on the net -- this could take quite a while, but there are probably some out there somewhere. If you are very lucky you will find one! When you do it will cost almost nothing....

In the meanwhile, you can use (this works with newer PSR's, I don't know about the 620) a program called OneManBand. This uses the MIDI I/O and a PC to load styles onto your PSR.

Ate Logo,

Bob

PS: You might want to consider buying a new (used) PSR now Jaaf. Even in Brazil, the price of a 730/630 or 740 should be not too much.
