Re: Dragon 32 RGB SECAM and video tests

The reason for the two VDG in the schematic is that one of them is actually the connector for the VDG socket on the motherboard and the second one is actually the VDG itself.

Re: Project 2

Yes, please!

Keep us posted here. I am not much of a facebook guy, especially because finding anything there is impossible. I like to be able to easily search older posts.

Does Mr Dig work properly?

I was talking to a friend on a spanish Dragon Users Telegram group and he said that he was having trouble playing Mr Dig, as he couldn't move the character and it drifted to the left side of the screen. So, I took the chance to test it while I was servicing my 64, and lo and behold, it happened the ...

Re: 6809/6809E compatibility

I consider it an option!

That it maybe detects an incoming clock signal and disables the internal one.

I've seen weird edge cases with several processors, but having it running without problems for more than 4 years... that would be too much to ask :mrgreen:

The surprising bit is that it works as if it were a completely compatible replacement.

Re: 6809/6809E compatibility

I know that, but my question is more if standard and E versions are interchangeable, and if they are not how come that I have a D64 with a standard 6309 working well.

6809/6809E compatibility

Hello, wonderful people! I'd like to ask about the difference between 6809/6309 and 6809E/6309E processors. It looks like the standard and E versions have a set of pins with different functions, and the direction of the E and Q pins seem to be reversed. I upgraded my D200 with a 6309EP, and on the o...
