Video driver thoughts
Re: Video driver thoughts
There is another small thought which I have just un-forgoton...
Someone suggested routing the MONO shifter output, to all the RGB inputs, basically so they will drive MONO to the RGB signals.. I think it was in part thinking about a intergrated UBE adapter..
Basically they should go direct to a VGA monitor and should work in MONO..
I guess anyone who has a spare video dac board could do some hardwiring to see this idea works okay or not..
Of course on a new MB it would probably require a multiplexer chip to do the switching.. But this shouldn't be complicated to do just needs the chip adding..
The slightly annoying thing is, MONO could have been injected into the analogue RGB inputs to the DAC, and the DAC could have switched between the RGB and MONO inputs, but we are using that function for the Blanking

Re: Video driver thoughts
Has anyone tried the v3 DAC board yet ? It should work as its a fixed v2 design , though don't think anyone's actually tried the v3 board yet...

Re: Video driver thoughts
Got the board but not the time
My plan is to use it on the STF Remake slim version viewtopic.php?f=64&t=1587&p=17564#p17564 and not put in all the unused RGB circuitry.
I should build the board anyway and plug it into the current STF Remake to see how it works.
