    Default What is this component?

    I've ripped off a pad whilst desoldering the bios from my Sega CD. B8, as shown in the red circle. I've found this on the schematics and it seems to be pin VA6 of the BIOS to R707. Thing is R707 points at a small chip, along with a few other numbers.

    I managed to get a continuity test with whats rest of the trace and it seems to be connected to all pins on that chip, so I'm a bit confused about what I'm supposed to join VA6 onto. Could anybody help please?

    I think that's what we called a buffer chip, when I was attending electronics courses. What it did was never fully explained to me. I know that my test bread board had one on it, and everything requiring voltage connected to it.

    A Black Falcon: no, computer games and video games are NOT the same thing. Video games are on consoles, computer games are on PC. The two kinds of games are different, and have significantly different design styles, distribution methods, and game genre selections. Computer gaming and console (video) gaming are NOT the same thing."
