What kind of drives does the Waveterm use?
What kind of disk controller?
For example:
96tpi (80 tracks per side) drives can read 48tpi (40 tracks per side)
disks, and can write them to virgin disks, but, when RE-writing them,
leave part of the old (wide) track alongside. Those RE-written disks are
readable by a 96tpi drive, but not necessarily by a 48tpi drive.
PC is NEC-style FDC.
WD-style disk controllers (such as 179x) can handle post index gap smaller
than NEC-style can. For reading with NEC controllers, that can often be
handled by masking the index pulse.
WD-style controllers can read sectors that have a WRONG number in the side
number field, but NEC can't ignore that field. The good news there is
on formats that use a wrong number in the side number field (such as
Kaypro DS), the WD controller doesn't MIND if it encounters the correct
number in that field.
SOME NEC-style FDCs can not handle 128 bytes per sector. Some can.
The FDADAP adapter's primary difference between a simple cable is support
of TG43, a signal to indicate that it is on an inner track, for
write-precompensation, etc.
