APOLLO X PRO (under testing/development)
A new APOLLO X (PRO) is under development

Here you can find the discussion on the first version of APOLLO X that is still available

I would like to know from you (there are many of you) which video features I should add/implement on the new version

- PAL and NTSC resolutions?
- 50Hz refresh rate?
- Scanline? (if I have enough memory in the chipset)
- Other request


To ensure a "Plug & Play" system, the goal is to make it in its own box and powered directly from the DB23 port, thus avoiding having external power cables (even the new chipset allows me to do this)

Thanks!

50hz is a must for smooth scrolling for what is basically the default for all pal machines

Scan lines have to be implemented correctly or they make the picture look worse.

Simply black / blank a line is not how scaliness work that method simply halves the brightness.

If you can implement a scan line “type” or “mesh” to replicate the actual beam across the horizontal plane as well as dimming or ghosting the previous line that would work great

After several PMs received this is the summary. Let me know if there is more

  1. Add resolution for use with old VGA monitors 640x480 @ 50Hz and 640x480 @ 60Hz
  2. Add the resolutions already present with refresh of @ 50Hz
 
I have some serious questions about this. What is the current draw? Why is the inside of the scandoubler not shown?

The quoted display resolutions are troubling - are these output resolutions? Different games and workbench settings have different screen centering and different overscan. How does it cope with that?

Basically no details are provided.
 
New board is coming..new CPU ,fast than previous

Now 640x480 (VGA) present
 
Matching a TFT native resolution is excellent for output :) Does it accept both PAL and NTSC input? There's a diversity of games and other software.
 
Why ignore key questions?

If it were open source (but it isn't yet), I could show you the schematic, the conversion system, the vector matrix, etc., but that's not the case.However, I can tell you that with the processor upgrade, I was able to improve things a lot and also add the 640*480 VGA resolution that everyone has been asking for.Furthermore, the next step I'm evaluating is an integrated PAL/NTSC system, which wasn't present in the first APOLLO X version, where you had to choose between PAL and NTSC.This is a plus, since it's not a given that everyone has a PAL Amiga and an NTSC Amiga...but it could be useful for anyone with this configuration and rightly wanting to use a single upscaler for any AMIGA.
 
I don't want to see the schematic, the "vector matrix" or whatever the hell.

I asked a basic question: Are the list of resolutions you posted here output resolutions? I asked a second question: how does it cope with different overscan settings?

This is not rocket scientist stuff here.
