Hello Vnews readers,

		This is my first message I have completed without 
		the help of a computer scientist, so please excuse my 
		typing.
		I have written a DR11W device driver for a interface 
		to a vector graphics system (Megatek) and I want to 
		try and transfer this from a SUN 3/160 to another 
		VME based OS9 system. I have, however, no experience 
		in writing drivers on a os9 system. I would, therefore,
		appreciate any tips on the following or examples of 
		the following.

		A) Books on system programming in the 0S9 System.

		B) Any examples of drivers for a character oriented device
		like an interface of the above type.

		or/and

		C) Any pointers to the differences between OS9 and 
		Unix system programming ( such as how the drivers is 
		annealed with the current core programs.).

		I would like to thank anyone for their help, should they 
		send any. And please excuse my simplicity if the programming

		task is essentially the same. I am asking because we are 
		considering the change between a SUN and and OS9 system 
		to gain real-time control over our system ,

				Thanks again ,
