Re: TT030 VGA picture quality

Really nice idea. I read about the OSSC here: http://www.atari-forum.com/viewtopic.php?f=15&t=20971#p346128 and it got me interested (but like evil, equally disappointed with the pause between interlace/non-interlace switching). But since the TT doesn't suffer from such issues (no interlaced mod...

Re: Falcon crashing when moved

Don't be too pessimistic here. From your description it doesn't look like a PCB damage to me (how else would i...

Re: S-Video on Falcon

I'm not sure whether it's good news or bad news but I have realised that I don't need it. :-) For some reason I had believed that the ScreenEye outputs an S-Video signal (which is rather stupid as it's just one RCA cable) and therefore to be able to reco...

Re: Falcon's 16bit bus myth - 32bit vs 16bit war

Simple rule of thumb: if it doesn't have a CPU and memory on the same expansion card, it can't have 32-bit memory access. The only exception here is the CT2A which does have its own 32-bit expansion connector but hey, it already has its own CPU and memory onboard. :)

Re: Phantom accelerator (by Phanatic).

Are the schematics available? The circuit sounds very simple, from your description it sounds like the stability is taken care of by the clock patch and not the Phantom itself. Not exactly standard one but mzry has succeeded to build one by this: https://mikrosk.github.io/clockpatch/Clockpatch-2.2....

Re: Phantom accelerator (by Phanatic).

Phantom looks like a simple and functional patch. Hoho, carefully. :) While Phantom is certainly way cheaper and simpler to build, it's far more difficult to install. You have to cut/scratch/solder a couple of very tiny pins (take a look at the DSP and you will get the idea). Something like CENTurb...

Of course, HDMI/DVI (digital input) is not interesting here. As mentioned, we're after an analog >100 Hz input.

It basically just contains a 50MHz oscillator that is fed to the Videl chip via pin 15 to allow higher screen resolutions.

LCD capable of 100 Hz?

While people are usually asking for LCDs able to cope with 15 kHz horizontal frequency, I would actually like to know whether there are still LCDs able to handle 100 Hz vertical frequency?

There's a few Falcon demos which are *really* unhappy with plain VGA/60 Hz.
