I plan to place the HDMI connection at the position of the VGA socket. 4 of the 8 required lines (GP16 to GP19) are already there if I use wire jumpers instead of R11 and R13. The VGA circuit will not be assembled as it is not used in this case.
I will separate the traces of GP12 and GP13 (as they are originally routed to the SD card) and route them together with the contacts of GP14 and GP15 to the DVI output using wire.Finally, GP20 and GP21 must be routed to the SD card. The rest of the board can be set up unchanged.
I have to order the transistors for the PS2 level shifters,but these are not required for the first attempts. Otherwise I should have everything I need here. Let's see how long I need this time, my eyes don't get any better with age.
Cheers
