Title: Anyway to have other devices play on the ctm 640 monitor
Post by: mark25810 on 23:25, 21 May 22
Hi there i have a CTM640 monitor and was wondering is it possible to get other things to play on the monitor, was thinking if there was a adapter that connects to the 6pin cable that has a scart socket on?

i have seen them for the oher amstrad monitor just not this

You can easily find the opposite, a male DIN to male SCART adapter to display your CPC on a standard TV.

That said, making what you need should be quite easy. Find the connectors, get a regular SCART cable, chop the extremes and solder the right cables to the new connectors.

i tried looking, i do not need to play my amstrad on another monitor, i wanted to plug something else into my amstrad colour monitor but id need a female din cable that also has a female scart socket on. they have cables like this for the other Amstrad monitors but for some reason not for the 640 monitor

Well, the reason is quite simple. 

CRTs take up a lot of room, so it's easier to keep the computer and connect it to a modern TV or monitor.

That said, the cabling is the same but with female connectors, so it should be easy to create one.

Also note that such a cable would only work for RGB input signals. For other input sources you'll need a converter or maybe pass it through something like a VHS recorder that may convert the signal and output it as RGB.

The diference between ctm 644 and ctm 640 was the 12v output for the  cpc 6128 floppy disk.

So the cable was the same in the two monitors.

you could make an adapter and run a device on it...
but..
the output from the device will need the right timings..
not all resolutions are going to work..
also the syncs will be different so they will also need converting...

what you really need is something like the MP-3 tv tuner which has a scart connector on the back for input...
theres also the SRX2000 TV tuner that has vga and rca inputs

You probably can connect any 8bit/16bit computer with a passive adapter, as long as it has a Composite Sync, RGB / 50Hz output. 

Many 8bit systems however only have Composite video output. That will then be much more complicated. Here is someone who added a Composite-to-RGB adapter to his CTM. Unfortunately the interesting part about the electronics is very wiggly so you might have to ask in the comments how it's done.

You mean something like this?

I used to use my old CTM monitor with my Amiga.  That cable was from a stall at one of the brilliant old Amiga shows at Earl's Court or something.  Asked on the off-chance, and they had one!

It worked very, very well and I don't seem to remember having horizontal alignment issues or anything (unlike most monitors I've tried since)
