   Hi.  Can
anybody provide me with some info on the IBM PGA/PGC adapters for
 the IBM PC/XT systems?

 I heard that it is one of the first video adapters with on-board transform
 capabilities, and that it is very ahead of its time.  Can anyone please
 elaborate?
 Also, where can I get some pictures, and is it still available for
 purchase?  
 Half-half acceleration due to built in CPU and can compute arcs, 
 lines etc for cad work I think.

 But I know PGA is grossly unusual design and unrealistic cost kept it 
 from very common plus it requires non-standard PGA monitor to go with 
 it.  Cost was about 5,000 I think.

 BTW, it is 3 boards package and monitor.  Saw both monitor and card 
 set but not in action. 
  If memory serves, the PGA had an 8085 processor on it.  Interesting
use of an otherwise general-purpose microprocessor.

  Indeed, an XT-class system with a PGA had a better processor on its
video board than it did on its motherboard.
