     Dear C-64 Netlanders:
       I have been doing some bit-mapped graphics on the C-64
and I have  encountered the problem of  having to use  memory 
locations 8192 to 16191 ( decimal ) for the bit image memory. 
Is  there any way  to use a different part of  memory for the 
image by changing an address in the VIC chip ?  If so I would
like to know how to do it.

   As well, is  there anyone out  there who  has written 6502 
( 6510 ) machine code for graphics primitives (lines, circles,
rectangles) and  plot routines for C-64 who  would  not  mind
sharing  assembly  source  code  with me and other interested
parties ?

  Anyone with any hints or suggestions are also encouraged to 
reply. 

                Thanks in advance --
                   Bruce Ross
