И вы вот тут смеетесь уровню контрастности, а я то помню, как в игровухе стояли 5 теликов, 3 или 4 из них были советские. Один зеленил страшно, другие показывали нормально, но настройками они не блистали. Был переконтраст и другие особенности того времени. И вот если вы реально не здорова ностальгируете по тем временам и впечатлениям, то почему бы вам не настроить телик так как было раньше?
"After discussions held with UMC we are able to provide to
you the following information as requested by you. The
picture processing unit was designed by UMC and its original
purpose was to produce and generate a video output signal
for Pal system TV's. The PPU in question was designed in
1987 and manufactured commercially a short time later. As
you are aware through your technical training it is more
difficult to copy an original layout than to produce an
original integrated circuit. The PPU was designed with aid
of CAD tools using existing functional blocks available in
its library. There are many types of PPU's available on the
market and we would be surprised if not all but most carry
some kind of resemblance due to their design characteristics
and their end result in terms of functionality. This
similarity can be noticed with a large number of integrated
circuits available on the market today.
The two devices cannot be directly replaced for each other.
Hence the two devices are not functionally compatible. The
UA6538 can process the cartridges designed for NTSC TV
systems whereas the RP2007-0 cannot do this due to its
inferior design. The interrupt signal timing between these
two devices are quite different from each other. This can
be tested by measuring on the TV game module (pin 19 on
PPU). The DRAM refresh circuits on the RP2007-0 for data
retention are not necessary for UA 6538, and please note
most importantly that the control timing and data retention
method for these two devices are totally different."
