Re: Dragon Beta GitHub

I have doubts about some resistors that I don't know what the value is; They were the following ones:

R25,R31,R28,R24,R21,R29,R30,R22,R23,R26,R27 and R20 since in KICAD there are not the values of certain resistors.

Thanks.

With which I am considering the possibil...

Greetings pere, it is correct in what you say in the signal output, RGB + sync. The part about the location of the pcb, my initial intention was to connect it directly to the vdg, but yesterday I realized that it had no socket. I had the idea that it had a socket since my American tandy 2 computer, ...
