Released today.
PTDQ is a video system for AGA Amigas that provides a chunky-to-planar method which is faster than the traditional ones. It is the higher-quality brother of
PTDS (formerly PED81C), another system based on the same core principle.

https://www.youtube.com/watch?v=witR2EE9No8[The video quality of the real machine output is heavily affected by the fact that the scandoubler did not support SHRES (so a real-time software trick was used to somehow produce the colors, although it is only a visual illusion and causes a sort of rasterline effect), the monitor did not support progressive PAL and the video was captured with an ancient phone at just 24.917 Hz. YouTube's compression degraded the video quality.]

Edit: I get a server error if I try to include the pre-formatted tables that provide some additional information; anyway, the tables are included in the documentation.
