The X9000 was RIGHT BEFORE the electronic manual revolution. It was probably the last model/system to be on paper only. The X9000 systems stuff that there are are PDF's of are the parts that were upgraded to Spectra/X9000 (W9). Unless someone has scanned in their manuals and wants to share, you may be out of luck...
Also, the X9000's never really had whole manuals, the manuals were in the form of supplements to the existing Syntor-X manuals to update them with personality board and control head info, which was really the only thing that was different from the original Syntor-X radios.
Some work was done to that end but not on the X9000, to the original Syntor-X. There was something made called an Xcat that allowed PC control of a Syntor-X radio. I think it allowed open VFO tuning and scanning, at least it allowed for easy PC programming, I'm not totally sure.
Have a complete one in good shape ...68p80101w95-D ...1992 sh ...yellow diagonal strip across the pc board print covers.
This was a later version since these were some of the last LB X9000 's that came in new from Motorola.
Has a decent section on the X9000 head which is why I kept it
