I'm looking at picking up an A1200 to add to my collection and most if not all are PAL machines. Can the video be altered to work on North American Amiga monitors?

Thank you for any information.

A1200 PAL to NTSC Conversion (this is on a Rev 2B PAL board). A NTSC board can also be swapped over to PAL bt you will obviously have to find a few more components.

The following tutorial will explain how to convert a PAL A1200 to a NTSC native A1200
Items that must be altered

(T) = top
(B) = bottom

- Remove R245 (B)
- Add R246 (T) 2.7K
- Change X1 (T) to a 28.6363MHz oscillator
- Remove Y451 (T)
- Remove C244 (B)
- Add R203 (B) 0 ohm resistor
- Add R225 (B) 0 ohm resistor
- Change R221 (B) to 1.2k
- Change R223 (B) to 1.2k


Items that may be required to alter

C243 removed (T)
L241 removed (T)
Q461 removed (T)
Z221 removed (T)
R243 removed (B)
R244 removed (B)
C244 removed (B)

Just altering the upper list of components was enough to convert to NTSC. the lower list will remove extra components from the Pal goodies section of the motherboard that don't appear to be necessary.
