Testing out my new ScanPlusECS scandoubler for my Amiga500. And it is really good. Though there are some con's, yet not anything bad.
On the plus side:
It will deliver smooth scrolling at 50hz. And I do mean smooth scrolling. The vertical scrolling of the introtext in Pinball Dreams are smooth as butter, as well as the scrolling on each pinball tables. Small details on the pinball tables does not flicker when the table scrolls up and down. The 50hz sync can be an disadvantage as well. I will address it a bit later as to why. As said. Smooth verical scrolling, and it has no lag whatsoever. Compared to a flatscreen tv that has a millisecond or two of lag. The image quality is less saturated in color, and details stand out better on a vga monitor. I can reattach the top part of the RF shield inside the Amiga, though I have to remove a tiny bit on the top-shield. The little shield that are mounted around the zorro-slot can be reattached as well.
The negative part:
The scandoubler puts out 50hz. Resulting in not all CRT/TFT monitors can be used. As an example, I have the following flatscreen monitors: 17 inch Samsung, a 17 inch IBM and a 21 inch IBM. Only the 21 inch IBM can be used, and I need to put the signal through one of those 4-way vga signal splitter boxes. It is a 150mhz box. Then the image will stand perfect, with smooth scrolling and fill the entire screen right to the border/bezel. If I do not put the signal through the splitterbox, the picture will have awefull vertical lines all over. Yet it is no big deal, as I have it hooked up all the time, because some ISA VGA cards will loose signal, and force the monitor into sleep mode. The box solved that issue. The last negative part, is that white is not 100% white. It has a slight grey'ish tint to it, and red are not bright red. Though I can not remember if the games logo/artwork in the intro of pinball dreams, was supposed to be red (like a firetruck) or slight pinkish purple (light red). As long as the details are more visible, and there are no lag and it has smooth scrolling, then I am fine with the colors being slightly off.
Conclusion...
If you only have an Amiga500 or Amiga2000, and the correct setup. Then this scandoubler is just a wonderfull little upgrade. Cost less than the IndevisionECS, and it is still avaliable as brand new. It has only one single jumper, that you need to set, depending on the Amiga being an OCS or ECS model.
EDIT:
Just googled pinball dreams to investigate how the colours are supposed to be displayed. And yeah... Looks like the ScanPlusECS reproduces them correctly. It is the TV (flatscreen HD-Ready) that are oversaturating the colours. That is a plus in favour of the scandoubler.
