I was wondering if I could re-purpose a little 4.3" screen such as this ONE here (https://www.ebay.co.uk/itm/385521917670)?
I take note it is using a composite signal, therefore more for a TV usage input. It has 2 inputs, I was thinking to use the non-reversing one. It is a little annoying it is 12v, but it is meant to be used from a car - anyone know of a similar one that can run from a 5v USB?
However, to output the signal from the CPC 464, I'd need to convert the RGB to a composite signal - which reminded me of the early MP1/2 modulators.
Then I stumbled over this wonderful article: https://www.cpcwiki.eu/index.php/RGB_SVideo (https://www.cpcwiki.eu/index.php/RGB_SVideo)
and I believe that is exactly what I need?
Does anyone have one of these devices knocking around in a drawer somewhere that they'd like to sell me? Although before that, can I have a sanity check that what I want to do can actually be done?
Basically, I'd love to have a small flip up monitor that I can place on top of the tape deck and use that as the monitor rather than the CTM 644.
okay, so after taking a look at this forum post (https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/anyone-tried-an-analog2hdmi-on-cpc/)
that sent me in the direction of this device RGB2HDMI (https://www.sellmyretro.com/offer/details/61490)- yes, I know it isn't composite video that I originally was looking for.
However, there are none available :(
which then led me to eBay here (https://www.ebay.co.uk/itm/234890201554?hash=item36b08c09d2:g:PkEAAOSwjOFhe-s9) - so it looks like I can purchase one of these devices.
But, this is not composite video? Well....I found that I have a couple of these screens (https://www.ebay.co.uk/itm/195544386713) sitting in a box (they were meant for an IBM PC 110 (https://en.wikipedia.org/wiki/IBM_Palm_Top_PC_110) project that never worked out) - they run on 5v and have multiple inputs.
I also have a couple of RPi zeros that I can repurpose too.
okay - if the original Bryce-made device is no longer available, I'll go this route for what I want to achieve.
If you can deal with HDMI and lag isn't an issue a Scart2HDMI converter could also do the trick, as long as it's a true RGB converter.
If the screen has VGA input, you can also use a GBS8200 (best with GBS control mod). That one works well with just 5V.
Hi Ynot,
I don't think I have any adapters left, but I can take a look. I may have some of the PCB's somewhere. Back then I built exactly what you are suggesting with a similar S-Video/composite monitor, but I changed the case to allow all the additional electronics to all fit in one unit.
It has the original Composite and S-Video inputs, plus sockets for CPC and CPC+. I never added a 12V Booster, so it still needed an additional 12V supply.
The screen is 4.3in.
Bryce.
