     Good idea!  But it is even cheaper (if you have access to a PC with
5 1/4" drives) to just do an image copy of the 5 1/4" disk onto the 3 1/2"
disk.  By image, I mean a sector-by-sector copy of the disk.  The two disk
formats have the same number of sectors per track; it is the number of
tracks that is different.  I've done this, and MINIX (256K) boots fine from a
3 1/2" disk on my T1100+ (I unfortunately bought the brain-damaged 256K
version).
