RE: CGA-to-VGA converter troubleshooting - MbeeTech - 28-12-2020
Hi Matty.
Thanks for documenting the process to get your output working here.
Glad I was able to help & get it sorted for you.
It is also great that I can now confirm the Video Converter will work with both
of these machines. I'll probably make input cables available as a purchasable accessory
for the converters as well.
I have both the BBC micro and Amstrad CPC on the way from helpful people
for a loan so I can make up cables & take photos during this week.

No worries Evan
Seriously, I really appreciated you taking the time helping me to get it work - I bought it originally so I could have one box that I could use on various different computers but with one modern screen ... instead of different old CRTs for different computers ... and so far it is working as I hoped.
The CRT for the Amstrad CPC464 I've been testing on doesn't work (power problem) - I want to get rid of it as I have a spare but that's hard when the monitor is required and doesn't work. I can now offer the machine, including a DIN-to-CGA cable, and point them to your converter box as a solution.
I started a new thread to document the machines I've got it working on - added a Yeno SC-3000H to the list today - small issue is the image seems right-shifted. The image was centred when I left V_SYNC floating but the colours were washed out - activating H_SYNC invert fixed the colours but right-shifted again ...
Cables would be awesome - I'm looking at buying a bunch of male-male 6-pin and 8-pin DIN cables from Aliexpress and cutting them in half so I don't have to worry about the DIN plug side of things.

Are your CPCs "PLUS" models with PSG DMA?
I was looking through the diagnostics ROM I have for it and there is a specific test for this - it plays music whilst you can test the keyboard.
