The model number of the "old" drive is

the "new" drive is FD55BV-36-U. There are differences in the jumper
designations between the models so I can't readily map the settings.
If I remember correctly, the 55B (Teac) is a "360K" 48TPI drive;
the 55F is a "720K" 96TPI drive.
A 55F could read disks written on a 55B, with some trivial additional
software (to step TWICE between tracks),
but a 55B can not read disks created on a 55F (unless it was running
extra code to double step)
