Elon Musk's Starlink project belongs to his company SpaceX. He plans to use tens of thousands of satellites to provide internet services to every corner of the Earth. A domestic company also plans to increase its investment in the development of space satellite networks to develop space internet. It is known that the research and development department of this company originally had 100 people, with an average annual investment of $a$ (where $a \gt 0$) thousand yuan per person. Now the research and development department personnel are divided into two categories: technical personnel and research personnel. There are $x$ technical personnel, and after the adjustment, the annual average investment of technical personnel is adjusted to $a(m-\frac{2x}{25})$ thousand yuan, while the annual average investment of research personnel increases by $4x\%$.
  
$(1)$ To ensure that the total annual investment of the adjusted research personnel is not less than the total annual investment of the original 100 research personnel, what is the maximum number of technical personnel after the adjustment?
  
$(2)$ Now it is required that the total annual investment of the adjusted research personnel is always not less than the total annual investment of the adjusted technical personnel. Find the maximum value of $m$ and the number of technical personnel at that time.
