FOUND: Genesis Model 2 with VA2 or VA2.3 motherboard

[GohanX]

I've been tinkering with Genesis and Sega CDs again, comparing the different revisions and mods and such, and I need a Genesis 2, specifically with a VA2 or VA2.3 motherboard as it's the only model 2 I don't have. Condition doesn't matter, but I'd pay more for a nicer one. If it has flaky power, reset doesn't work, or whatever that's fine as I can fix it as long as it will boot a game.

I'll check mine when I can next week, I have a few. Can you tell w/o opening them up?

VA2:

VA2.3:

Just open the flap and compare the traces. These images are from Ace's comprehensive "telling apart good Genesis from bad ones" in the 'tech aid' section on sega-16. I'd link it, but the site's been all screwy for a while. But if you want to try to navigate the forum, that thread is stickied.

Thanks, prof. The blue wire is a dead giveaway on the 2.0, it’s more difficult to spot a 2.3.
