The problem is it is Hard Copy!  It's got alot of timing diagrams and related
graphics material.  Fine print as well, so I'll just give a quick strapping
review here now:

       TEAC FD-55GFR

               default strapping:  D1, DC, FG
               
               Adjustable:     D0-D3,  Addressing
                               U0-U1,  LED indicator control
                                       (Use with IU; In Use signal)
                               ML      Spindle motor On/Off control
                                       (Off state: MOTOR ON * disk
                                        On State : [MOTOR ON + LED] * disk)
                               IU      Will expect IN USE signal on pin 4
                                       of 34 pin interface if jumpered.
                               RY/DC   Selects function of pin 34 signal from
                                       drive: either READY or DISK CHANGE
               Operation mode straps:
                               LG      On state is pin 2 LOW = High density
                                       Off state is pin2 LOW = Normal density
                                       (Pin 2 signal is HIGH/NORMAL DENSITY)
                               E2      Selects output condition of INDEX and
                                       READ DATA pulses. (Complex waveforms)
                               I & IS      I On state: dual speed mode 300/360 RPM
                                               (Controlled by pin 2)
                                       I & IS both Off state:  360 RPM always
                                       I & IS both On: Dual speed with
                                               maintenance of READY signal
                                               during High/Normal change.


Sorry I skipped over U strapping a bit as well as E2, but you get the idea I
hope!  This would have gotten me going when I had a 55GFR. . .

Happy strapping!!! 8-)
