I remember you being in contact back in January about Sam drives....

The actual disk drive mechanism used in the original Sam floppy drives are a
slimline version that were made by Citizen and haven't been available for years
(another type of slimline was also used around 1995 or so - NEC i seem to
recall, I had one and it seemed to be 'smoother' and quieter than the
citizens... but it died due to a damaged shutter on a disk).

A PC disk drive can be used with the same circuitry - using the WD1772 disk
drive controller IC - that is on the small board which is soldered directly onto
the back of the original disk drive units.

If you may still be interested in a complete disk drive system for the Sam,
please see the more detailed information that is now at my website - link:

If it is just a mechanical fault with the actual mechanism of your disk drive,
then the WD1772 controller can be salvaged from it and re-used which would save
about £10.
