hi again
finished scanning the manual - 300 dpi PDF can be retrieved from this Internet Archive URL:
Lynx 470 Users Manual
Don't think I can upload the 66MB file to this thread though, but the relevant page for the alignment cable is attached.
Unfortunately, their diagram doesn't correspond to the actual coloured wire order on the 10 pin female IDC connector..
Suffice it to say, the Lynx 470 gets it's 5V supply from the large clip connector with the Red/Orange wire attached to the 5V pin on the floppy drive.
Ground is normally connected via the common ground pins (odd pins) in the floppy cable, rather than the Grey or Black wires.
Minimal connections to use the Lynx 470 would be:
Red/Orange = 5V
Yelllow = Radial (ie RW Head output)
Green = Radial (RW Head output)
Blue = Track0
White = Index Pulse
The floppy drive's service manual would/should have an explanation of whether the index pulse is a +ve (rising) or -ve (falling) pulse is generated by the drive, which is set on the Lynx 470 by the index toggle switch. The manual recommends +ve for 8" floppy drives, and -ve for 5.25" floppy drives.
cheers!
