Hello can anyone confirm if I can use a CPC monitor with a PPC512/PPC640 and if so can I use a MP1 or MP2 modulator to power and display via a tv. I read this at old-computers.com.
Thanks in advance.

That sounds unlikely, as the PPC512/640 had a TTL-level CGA/MDA output, which is unsuitable for driving any kind of analog RGB monitor directly.
It's possible to build a relatively simple semi-active converter though (search for CGA to SCART), but I don't know if the CPC monitor could handle the 60 Hz scan rate.
EDIT: my bad, it seems that the PPC512 (or at least certain revisions) included a 6-pin DIN connector for Amstrad's RGB monitors:

Well, it'd be interesting to see how CGA colors were rendered through the RGB output :o 8)
As far as I can remember, the analogue RGB outputs were rendered with a simple resistor network from the TTL levels, much like those CGA to SCART adapters work, so I suspect the picture quality was still crap CGA.

Well, I was referring to a "dispute" about CGA's color 6, which
should be Brown instead of Dark Yellow ;)

So, does the PPC512/640 display the One True CGA Palette the Way It Was Meant To Be ? (TM) ;D
