Does anyone know if System V/AT supports the Perstor 16 bit hard disk/floppy controller? The Perstor normally formats to 31 sectors per track, which V/AT can't handle, but it is also (supposedly) register-level compatible with the WD1003-WA2 controller. mark --- * Origin: MaMaB--the Machine in Mark's Bedroom *HST* (Opus 1:363/9)
