Testing a CTM 644 without a CPC.

[generic486]

I recently bought a lot of comps but included was a CTM644. Since I already have a colour monitor I was thinking of parting with this one.
However, before I do, I'd like to see if it works. I was wondering if there is anyway I could connect it a Composite source or another old computer with similar video output pinouts.

I have powered it on, and I do get 12V from the power supply.

In case you have some entertainment device capable of SCART RGB out you can make an adapter:

Picture will be darker though as expected. You may also get away with a CGA card by connecting RGB, and composite out to H/V-sync.
