Hi,
Have aa look on the Stardot Forum, where the RGB2HDMI converter was developed, I a sure there will be more information there and maybe someone that has built the Spectrum and ZX80/81

Do your really need a converter to HDMI? If it's enough to have a converter so that you can view the output of a QL, here is the thread for a cheap converter (for QL) to VGA:

Re: who can shine a light on the hoglet rgd to hdmi converter
Derek thanks for all answers ,
right now i have a working pi + cpld pcb , i have info on my monitor , BUT ......
i thought i need an interface-pcb to connect my fe. ql to .
but in all text regarding this project it says that the new pcb ( i have ) allows a direct connection , but i can not find any nfo regarding that.
so a little problem there .
got the latest firmware running , but now need to verify my soldering as the firmware does not recognise the cpld

Re: who can shine a light on the hoglet rgd to hdmi converter
Have you flashed the CPLD? if your CPLD was pre-flashed for testing purposes like some of the ones I purchased , then you may need to cut the Jumpers and use the beta (or was it alpha) version to flash with. Ideally double and triple check your soldering. In regards to what else is needed , just the cable Din Cable from the QL to the hat.

too small for my eyes , i can only do that iduring the weekends if my eyes had some rest ( getting older ).
the chip came from a closed reel packaging .
