What no one has grasped yet is that the actual _mechanism_ is an MFM hard
disk.  The Sider has a hard disk controller board in it that provides the
SASI interface to the MFM drive.  It's most likely a Xebec S1410.

MFM hard disks can be had for cheap.  Any drive will do as long as it has
_at least_ as many cylinders and heads as the old drive.  One caveat,
though.  You should generally avoid any drive which declares that it
is/has "wedge servo" since not many SASI controllers could deal with
those drives (the Xebec 1410 being one of them).
