Well, the general idea with collecting for decapping has always been, "the more, the better" since it gives Dr. Decapitator room for failure/improvement in regards to getting a clean image and/or probing the device in various ways.
The thing we have to remember is that there are various models, so I would say three of each individual revision (or just three of one revision) would be a reasonable goal for now.

I think the one person who can confirm this is byuu.

that's good, i agree, I just wasn't told I would be receiving several. I wasn't sure, just trying to keep communication good and open.

So the second was from a mystery sender?

Honestly for decap purposes, all they need is the plastic chip body. They are going to use acids to eat off the plastic down to the silicon, and photograph it from there. The leads are unimportant, and unless you have a gorilla do the work for you, it's not likely you will damage the chip internals by cutting the leads.

This.

I've bought you three units (as discussed via IRC and email). I would ask you to cut off the CPU, PPUs, SPC, DSP (after photographing the board). Don't pay any attention to preserving the leads. If you need some monetary compensation, let me know privately.

I will send you the decapsulation address by email.

Question is, are these three units matching sets or are we going to have a mixed bag of chips?

I don't know, I guess we will find out. I don't know of any easy way to get this information out of Ebay sellers of used units.

sorry, I must have forgotten / misunderstood that there were three sets, but that's not a problem, and no compensation is necessary, I'm more than happy to help and thankful for the opportunity to be part of the process.

I'll do my best to document my work, label what I ship, and package it with extra care.

Perhaps someone watched your now unlisted video and saw the address, then decided to send you another unit?

Well, panzeroceania said he's gonna use the Lion King debug menu to identify the units. I really think identical sets of chips would be beneficial, though.

Is it Dr. Decapitator that is doing this?

Post Re: reverse engineering: request for chip donations
so I received the 3rd Super Ninendo deck a few days ago.

I picked up a yobo power supply an The Lion King at a local Game Crazy. All three power up. I'm going to be making a video and breaking them down very soon.

If anybody's still interested in donor chips, I just bought a DOA SNES that I plan to tear apart for the cart slot. If it turns out it's actually actually just a dead power supply or dirty contacts, I'd be happy to remove any worthwhile chips and send them off (I'd be willing to do it regardless, but if the console really is dead, the chips might have been damaged...).

I just got the SNES today. The case was pretty badly banged up, but the PCB's look pretty solid. The power barrel jack was smashed, so that may be the source of the problem, I'm going to try hooking up a 5v power supply directly to the 5v rail, bypassing the 7805, and see if we can't get this thing powered on. It's one of the older models, with the separate sound module, if that makes any difference to anyone...

I found my ChipQuik. I have a S-CPU, S-SMP, S-DSP, S-PPU1, and S-PPU2 ready to go. Just gonna clean up the pins a bit and reclaim as much of my ChipQuik as I can. Anybody who wants them, just give me an address and they're all yours. I did test the console before pulling the chips, and it worked fine, so they're good.
