Strange Teledisk question

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.
