Re: Build your dream computer

Missing the point. The TV signal is made up of RGB components. So you could tweak where the mid and low levels of a 2-bit RGB lie fairly easily through resistors in D-to-A conversion separately for the red, green and blue channels. But not for every colour in the palette individually. missing the p...

Re: Build your dream computer

very sure - for example, every day i'm seeing very little (if any) magenta but lots of beige(s) Jack Tramiel says “I’ve got just the machine for you!” nope, one of his machines got stinkin' sprites but no proper RED, and the other one emits sound thru the "text editing device", nuff said :mrgreen:

calculated from this, calculated from that... why not just pick the most prevalent real-world colours?
Are you sure there are colors more prevalent than others in real-world?

Re: Build your dream computer

The DAC is likely to be a resistor type. So although some ‘tweaking” of resistor values is possible, or some extra logic can be added, it does mean that an arbitrary set of colours is unrealistic for the price point of a low cost computer. low-end (and low-cost in 1982) atari 2600 got 128/104 colou...

Re: Build your dream computer

Don't forget @Lethargeek, we are choosing from stuff available in 8bit home computers of the 80s. well, i didn't - all the tech was there at the time and the machine using it should have been cheaper than the c64 or the atari 800 (at the very least) while looking almost as good (sometimes better) r...

Re: Build your dream computer

Imagine if you would that you are back in the 1980s and have access to all the home computers of the time. Being an exceptionally gifted individual you can take aspects of any 8bit home computer of the time and build your own. What aspects of what computers would you take? To get you started... It ...

Silence, I said!

Public beta 20 is here! Some people complained about occasional annoying sound crackling over the silence. It appears to be winaudio problem, and it can actually happen anytime and not just with this emulator (but harder to notice if a loud sound is playing). AIU sometimes windows doesn't send the ...
