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-)
