Anyone knows what this is and why it has no number? It looks like HVC-CPU-07 but there is a difference where I put arrow pointing to.
Could you have placed that arrow any farther away from what you want to point at? Is the arrow pointing to the capacitor? The LIS139? This looks just like the one over here. HVC-CPU-07 seems to be somewhat different but both the cap, the LIS139, and it's optional cap are there: HVC-CPU-07
So this might be the first revision famicom? I didn't think of that, thanks. But strangely, it looks more like -07 revision. Only at the arrow, the -07 revision has a 330P text which my doesn't. It is the ONLY difference between this and the -07 that I can see. But okay, according to the japanese blog (thank you for the link), it says that revisions 1-4 were not labelled I think the translation says. And yes it does look exactly like it.
If you notice the chip revisions it has the very earliest CPU and PPU. Presumably it was one of the recalled consoles. The date codes suggest that the console was made approximately the second week of August 1983, so only a month after launch.
Yes I noticed that too! What does that mean? Aha interesting. Thanks! I'll see if I can make use of it some way. For reference I took a photo of the back as well, should anyone be interested.
Kinda surprised you don't know already, but what I was asking was if the PPU was soldered onto the board or if you can remove it without desoldering anything.
I think fredj meant does the fact that the ppu is socketed confirm it is or isn't a known famicom hardware revision...
