Thanks Lee, and here’s another picture…
The bread board as it was moved from work to home. Starting from right, the PCB3 video output with the grey flat cable to be connected to the RGB video processor from PCB2 and the coloured 5-wire bundle to be connected to PCB5 “deflection and EHT”.
In the middle, the RGB amplifier connecting the PCB3 with the HDMI converter (if you look carefully you see the small PCB between the RGB amplifier and PCB3 containing the three 270Ω resistors).
To the left, the HDMI converter. Don’t comment the neatness… I know, but it works.
And the bread board… it’s a piece of teak wood;-)
