Right, I've got my Amiga and my dad and I have fitted the internal scandoubler in a similar fashion to Doppie1200. First of all PAL modes are completely fine. I can't test the different screen modes yet because the prefs didn't work on the existing hard disk installation which was almost trashed anyway. I can't reinstall workbench because the disks are foobar'ed and won't even boot. Other disk are the same untill formatting. I've ordered another set of disks to use but if I have troubles with these then the drive could be out of calibration (need new drive).

Anyway, through the scan doubler, in a workbench screen (booted from HDIntall disk) I'm finding that Whites are slighly off, they have a slight yellowish tinge to them. Could this be because of the reduced colour pallette, is it because of the relative darkness of shadow mask monitors? Or is there something I've done wrong?

Sadly it is true. I checked it by connecting both my 1084 and svga. The copper sky on xtr-racing is different.

If the DCE flicker fixer would use 16 bits colour that would explain the effect. It would not be able to mix all the colours needed to produce the gradient.

So; after this thread I can summerize this about an internal scandoubler:

Minus:
-Could be a hassle to fit inside
-Does not reproduce all AGA colours (16 bit)
-Has a tendancy to get hot

Plus:
+Interlaced modes are rock solid
+Use of most VGA monitors (which has alot of advantages on its own)
+Access to more screen modes (15..31kHz)

Sure this list can be enlarged. Maybe this can turn into a FAQ or something.

Mainly because of this minus:

-Does not reproduce all AGA colours (16 bit)

I've decided to sell my DCE internal flicker fixer, I was thinking in the range of about £50.

BTW With my Doppie1200 like A1200 mod, it didn't get that hot at all.
