To operate a NTSC machine like a PAL machine you have to do much more than changing VIC/VDC.

The only info I know about transforming a ntsc machine into a pal machine is written down for a c64.

You may have a look at the cbm-faq:

Quote17.2.  How can a turn my NTSC-M 64 into a PAL-B 64 or vice versa?
 
  Changing a C64 from stock PAL-B to stock NTSC-M or vice versa
  requires swapping in the approproate VIC-II chip and the appropriate
  crystal, as well as changing a jumper on the motherboard (The jumper
  has printing near it that indicates whether to cut or connect the jumper).
  Also, if you have a version 1 KERNAL ROM and want to use the built-in
  RS-232 routines, you need to either swap KERNAL ROMs with the other
  computer (not recommended), or obtain a revision 3 KERNAL (recommended). 
 
  Now, if maintaining stock operation is not a complete must, or if you
  just want to tinker, the crystal and jumper modifications can be made
  optional. 
 
  The VIC-II chip has a relaxed tolerance for timing, so it is possible to
  run an NTSC-M VIC-II with a PAL-B crystal and jumper settings.
  The converse is possible as well.  Since the crystal frequency is used to
  generate the frequencies for the TV and monitor output, your TV or
  monitor may not like the resuling hybrid signal very well, but it won't
  break anything.
 
  In addtion, the jumper indicated above determines the divisor used to scale
  down the crystal frequency for the CPU.  For PAL-B units, the divisor is
  18, and for NTSC-M units the divisor is 14.  The Commodore 64 will operate
  regardless of the crystal frequency and state of this jumper.  Therefore,
  to speed up a 64, one can install a PAL-B crystal (17734472Hz) and change
  the jumper to use the NTSC divisor (14) to increase the operating
  speed of the machine to 1266748Hz.  However, note that any operations (disk,
  rs-232, special VIC tricks) that require synchronized timing may fail in
  this "non-stock" scenario.

Hello,

allow me to introduce myself ... my name is "dmc"

I am 38 years old and live in germany. I am one of the forum64 admins and I registered here because I love my herdware. The C128 was the first (nah second) computer I got from my parents. The first was the C16 which was sold by a local disounter over here. Since then I collected many of the 8 bit machines. In my spare time I repair those old classics and try to keep them alive (which can be a really tough task nowadays).

Actually I am repairing the power supply of one of my dcr's which produces a really bad picture with nice humming bars on the screen.

Sorry for my bad english. I try to get better 

Michael

As far as I remeber you can not connect your ntsc machine to the 1084 in general. If you have an old 1084 it will show the ntsc picture but colors are missing. The newer ones (1084S D1/D2) have serious problems displaying ntsc video.
