Need Fuji M2312 info

OK, here's a paraphrase of the information I have from the manual for the 2311/2312 drives Switch SW1 at location E3 (on the CNAM PCB) Positions 1-3 : drive select. Switch 1 = LSB, swtich on = logic 1. Position 4 : Drive type. Off = 2311, On = 2312 Position 5 : Tag 4/5 Enable. On = Enale optional Tag 4 and Tag 5 functions Position 6 : Sector mode. On = variable soft sector, off = hard sector Position 7 : Write protect. On = Writing disabled. Secotor count configuration switchs, SW2 (location A26) and SW3 (location A24) of CNAM PCB. Each position represents a inary count of the byte clock : Sw2 position Value 1 1 2 2 3 4 4 8 5 16 6 32 7 64 SW3 position Value 1 128 2 256 3 512 4 1024 5 2048 6 4096 7 8192 To calculate setting from sectors per track : 1) Calculate number of bytes per sector = 20480/(sectors per track) 2) If the result is not an integer, round _up_ to next highest integer 3) Set SW2 and SW3 to number of bytes per sector (result of step 2) - 1 (to allow for counter reset clock). Switch ON if bit is a 1. 4) To determine how many bytes the last sector of each track will be short, multiply (bytes per sector (from step 2)) by (sectors per track) and subtract 20480. OR for a given sector size : 1) Set switches for sector size -1 (to allow for the reset clock) 2) Calculate sectors/track (= 20480 / (bytes per sector)) 3) If that is not an integer, round down to get actually secotrs per track. 4) Calculatr size of last sector = 20480 - (bytes per secotor) * (sectors per track) [That is a lot simpler than the procedure in the manual, but seems to give the same results!] -tony
