To (partially) answer my own question, there is some info in the NETBSD rd
driver. (rd.h and rd.c)
I guess no one has tried coding up a SS-80 or CS-80 drive simulator yet..
rd.c
/*
* Misc. HW description, indexed by sc_type.
* Used for mapping 256-byte sectors for 512-byte sectors
*/
const struct rdidentinfo {
u_int16_t ri_hwid; /* 2 byte HW id */
u_int16_t ri_maxunum; /* maximum allowed unit number */
char *ri_desc; /* drive type description */
int ri_nbpt; /* DEV_BSIZE blocks per track */
int ri_ntpc; /* tracks per cylinder */
int ri_ncyl; /* cylinders per unit */
int ri_nblocks; /* DEV_BSIZE blocks on disk */
} rdidentinfo[] = {

/*
* Several HP drives have an odd number of 256 byte sectors per track.
* This makes it rather difficult to break them into 512 and 1024 byte blocks.
* So...we just do like HPUX and don't bother to respect hardware track/head
* boundries -- we just mold the disk so that we use the entire capacity.
* HPUX also sometimes doesn't abide by cylinder boundries, we attempt to
* whenever possible.
