Declare interest.

Does it handle the SuperHires PAL and NTSC modes?
The output image is shifted to the right on the LCD monitor?
Can you show a full PAL interlace source and output comparison?

I'll be able to play with it over the weekend again. I'll post new pictures then.

Ok, so here's an update regarding this item....

As promised, I went on to test it a bit more and post some new pics. Even went a bit to far and bought an old VGA CRT to hook it up to this thing.
As I was fiddling with it, wires soldered to the daughter board which is attached to ALICE broke loose and took the pads with them as well (daughter board runs VSYNC and HSYNC signals from ALICE chip to the main PCB).

So I had to fix the daughter board somewhat. While at it I wanted to improve the thing so the wires have much less chance of getting pulled out again.
Therefore I've drilled two holes through the daughter board and ran the wires through them so the holes act as a strain relief - this is much more sturdy now than the original ever was.
Also repaired the connection on the bottom side as the pads have been damaged as well - not my finest hour with the soldering iron but it works.
Noticed the PLCC socket on the daughter board had a small crack (everything was still working fine but it had been cracked and would go sooner or later), so i replaced the socket with a new, quality 3M one.

Here's the picture of how it looks now (mounted in A4000):

And now some more pictures for comparison, as requested:

More pictures while hooked up to the 16:10 LCD:

As for the comparison pictures - keep in mind that on the left is just a regular telly (I do not currently own a 15kHz capable monitor). Also, picture quality and geometry on the VGA CRT/LCD is also subject to your monitor and adjustments - I made no particular effort to adjust the picture to best possible level.


So, to answer the questions: yes, it does handle pal and ntsc modes including super hires and the output is deinterlaced.
The position and whatnot on the LCD and CRT depends on the settings your LCD/CRT provides and on the adjustments you make.
As the output from this thing is analog (VGA), you'll have to play with phase and clock, horizontal and vertical positioning, stretching/sizing etc etc.

As the pads on the daughter board got damaged I was thinking of a price reduction, but since it does work perfectly and the strain relief really does help preventing the same thing from happening again + the socket has been exchanged for a new one, I'll do a symbolic price reduction just because the fact it has been fiddled with - updated in the main post.


Also, the two people declaring interest in the thread never sent a PM so I consider the interest queue empty.
 
Not interested, but wanted to add that these work very well for the CD32 if you trim the Alice daughterboard somewhat. In case you wonder about drilling holes and trimming: It's a single sided PCB that really only carries the two mentioned signals out of Alice.
