Brass · 31 October 2006, 20:59

Why do you ask?

Ok, we discussed this with Brass.

http://eab.abime.net/showpost.php?p=275840&postcount=8 is still valid.

The circuit there will only support looking at one half of the Amiga screen at a time, it does not accelerate the colour signals.

The syncdoubler circuit on aminet has a multivibrator tuned to the VGA frequency, then it is either trigged by the RGB signals on the beginning of the line or by another multivibrator that is tuned to vibrate every half an Amiga line.

Thus you can select whether you get the first half of each line on the VGA screen or the second half. Meaning you get either the left or the right side of the Amiga's screen at a time, stretched to fullscreen.

It looks like Ive found something based on the circuit on aminet ( possibly ) bit was built by a japanese engineer, the circuit looks like its not to hard to modify from NTSC to Pal so I thought it throw it up so you all could have a look.

Brass - did you get this up and running?

Brass · 19 December 2007, 07:24

I didnt build this in the end as I found a commercial unit which was cheaper.

andy · 23 December 2007, 20:36

Do you have any links, names or information for the unit that you used, Brass?

I keep searching, I keep looking... but I haven't found anything yet. Well, not at the right time or price! One day!

I am thinking about selling my Scan Doubler and getting an LCD screen for the Amiga to handle interlace modes for Workbench, although i wouldn't have a clue which one to get. ?

The Scan Doubler is fine for games at low resolution, but crap for high res interlace.
