<DIV>The model number for the Colortec is correct. Their was an
optional modification to the Proc Amp that was called Interswitch.
This was for the 405 and 819 standards used in Britain and France. It was
not required for PAL. As far as I can tell, the Proc amp came in 525
/ 625 dual mode. </DIV>

<DIV>The other area that may be different is the filter in the signal
system. Pal has a much higher bandwidth so that the filters were wider
than NTSC. It may not be too much of an issue but with a 4.43 sub carrier,
this could be an issue. We need an expert from across the pond to tell us
what the filter was in the signal system.</DIV>
<DIV> </DIV>
<DIV>The Amtec and Colortec were 6 MHz bandwidth devices so these will not
affect the performance as the machine goes between standards.</DIV>
<DIV> </DIV>
<DIV>Servos and all other parts of the machine were PAL ready.</DIV>
