I took a look on it on my tft monitor and they also look very good.
In direct comparison to my lossless compressed version I noticed that at
the edge between the row pictures
ptgui does get the color blending very good but you can see some edge in
luminance, whereas
it is the other way around with your picture. Luminance fits, but some
slight change from green to a more yellow green is visible.
On the other hand -> You have to know where to look for and it also
takes a while until you really notice it.
I would call it as good as it can be.
For a printout the question is if you want 'true' colors or more
details. Then you might change it to CMYK and Auto Level each color
independently.
My guess for normal dithering is that the printer should have at least 4
times the resolution if you use mixed colors.
As a plain estimation for A0 if you use 70 cm width and have 20000
pixels in the image is about 715 dpi base times four nearly 3000 dpi.

Tommi Lempinen asked me if I will take a map of the SID when he sends me
the chip.
I'am not sure in what shape it is yet. It should arrive here within the
next [two?] weeks.

Yeah if he is still reading the list, any comment on your possibilities?

Hehe, a co-worker in research asked me lately how my 'neo-archeology' is
going on...
