Ports seem to be:
fbfa = -----011-----010 a2=1 , a1=1 ,a0=1 (write)0 sdh fbfb = -----011-----011 a2=1 , a1=1 ,a0=1 (read) f9f8 = -----001-----000 a2=0, a1=0,a0=0 f9f9 = -----001-----001 a2=1 , a1=1 ,a0=0 (write) ??? f9fa = -----001-----010 a2=0 , a1=1 ,a0=0 (write) fafa f9fb = -----001-----011 a2=0, a1=1,a0=1 faf8 = -----010-----000 a2=1, a1=0,a0=0 cylinder low faf8 = -----010-----000 a2=1, a1=0,a0=0 cylinder low ------2-------010
f8f9 = write precomp? FBFA - drive select (write)sdh??? FBFB - wd1010 write command to WD1010 (write)/wd1010 read status register from WD1010 (read)
F9F8 - WD1010 data register (read/write)
F9F9 = wd1010 sdh register (write) (seems more like sdh)
F9FA = wd1010 sector count register (write)
F9FB = wd1010 sector number register (write)
FAF8 = wd1010 cylinder low register (write)
FAF9 = wd1010 cylinder high register (write)
FAF8 = cylinder low? 1111101011111000
FAFA = ?
