We have to admit, we expected to be bored through [The 8-Bit Guy]’s presentation, only to stay riveted through his comparison of early graphic card technology.
Some presentations get a bit technical, which isn’t bad, but what is so interesting about this one is the clear explanation of what the market was like, and what it was like for the user during this time. For example, one bit we found really interesting was the mention of later games not supporting some of the neat color hacks for CGA because they couldn’t emulate it fully on the VGA cards they were developing on. Likewise, It was interesting to see why a standard like RGBI even existed in the first place with his comparison of text in composite, and much clearer text in RGBI.
We learned a lot, and some mysteries about the bizarre color choices in old games make a lot more sense now. Video after the break.

If you’re working with a CGA, EGA, or RGB gaming system this inexpensive board does a great job of converting the signal to VGA so that you can play using a modern display. But what if you have a SCART connector as an output? That’s the situation in which [EverestX] found himself so he hacked in SCART support.
The first step is to source a female SCART connector. He grabbed a coupler off of eBay and cracked it open, yielding two connectors. Now comes the wiring and you may have already noticed that there’s a lot more going on here than the color channels, sync signal, and ground. Technically that’s all you really need to make this happen, but the results will not be good. First off, the sync signal for SCART tends to be rather awful. That’s where the blue breakout board comes into play. [EverestX] used an LM1881 to grab the composite sync (yes, composite sync, not component sync) signal as a feed for the VGA converter. He also added in an audio jack for the sound that is coming through the connector.
