Re: Falcon Csync video fault.

Because originally I followed a guide on removing the modulator and replacing it with a composite output plug connected via that chip. I didn't know this was incorrect. So you're saying if I route my composite output plug via a patch cable underneath the motherboard to pin 12 of the falcon monitor ...

here it is when I upload TOS 1.62, it STOP at 3FFF3 and I INSERT another EMUTOS.
It doesn't start at 4000A:
Where you get 4000A from ? The second file starts at 40000 (which I said before) . I think you need to switch to 8bit view...

Re: Falcon Csync video fault.

Chris do you have any thoughts on that? About where I'm routing my composite signal from. Why are you not using the proper CSYNC output ? That is driven via that capacitor and its where I drive from. I did route pin 9 via a 1K and then via that cap to drive it that way, but didn't see any point as ...

Re: Make my own DUAL TOS progamming

I don't know what your doing there..

But you just load in one ROM file and it should end at 40000 , then you just insert the second ROM at that location.

Re: Make my own DUAL TOS progamming

You can simply use something like hexworkshop to merge 2 ROM files into 1.

Or if this is just a one off, upload both files and I will do it for you.

Re: Falcon clock buffer patch V2 progress

Built up a board for testing.. v2.jpg I've had to put back the 100R on the input, it was ringing up and down 2 volts above and below 5V! IMG_3893.JPG I will try and build up a couple myself to get them back into stock. Though the rest will be sent off to be assembled as I haven't got time to build u...

Re: Flashy Clock - Yet another DEV board

I'm already producing the falcon clock modules, so this dev-board will use one of those. I'm actually more interested in the NVRAM side of things to store settings for the SEC booster etc. Though of course, this can ultimately be ported to the STF remake project. Writing the software to program the ...

Falcon Csync video fault.

I had a email a few days ago from Steve asking about a capacitor bulging problem after re-capping his Falcon motherboard.. But this actually gets more interesting later... This particular capacitor is in the video circuit, or more explicitly, it is the coupling capacitor for the composite sync signa...

Btw, which clock module you thinking of using? Things like the DS1307 are very capable and very cheap as well.
Will be using the falcon RTC modules.
