Hello, are there different versions of this disk for PAL / NTSC
machines, or is there only 1 version that works with both systems?

Hello Ciccio,

I think there are no PAL/NTSC diskdrives. The only difference is the
PSU (240 or 110 Volt) and the stroboscopic cart at the drivewheel (50
Hz or 60 Hz) About a year ago I buyed a 110 Volt SFD-1001 diskdrive
from an American guy and only replaced the transformer for a 240 Volt
version (from a donor 1541 who has the same), nothing more.

The drive works 100% with my PAL C64, so I'm almost sure there are no
different versions of a alignment disk.

Regards, SAM

you are right, the drives are the same in pal and ntsc world. and
nevertheless, the process of aligning has zero to do with pal vs ntsc - so
there are no different alignment disks either :)

Every program has at least one bug and can be shortened by at least one
instruction --- from which, by induction, one can deduce that every program
can be reduced to one instruction which doesn't work.

yes they are! ... ,the drive connected to a NTSC system works at 300
RPM and PAL works at 320 RPM , im use a Drean Commodore 64 PAL-N
System and 1541 Disk Drive and Works at 325 RPM .

this is the last page scaned manual , read this ...

not entirely. what they mean is, that if you use their software, which is
written for a ntsc _c64_ on a pal _c64_ - then when the drive spins at
correct speed of 300rpm, the software will display 320 rpm. this is correct
.... the "kwikload" copyprogram, which also has a rpm display feature, has
exactly the same problem (its also written for ntsc c64s).
