Cool. Iv'e only seen CPU-02 through 08.
As mentioned above though, revisions CPU-03 and below are noisier.

Apperently its called "黒猫SPC" from http://kurohane.net/seisanbutu.html

My first SNES pooped out a few years back, but of course I kept it. It has the removeable APU so I would like to build an SPC player from it. It would be pretty wild to control it live. I wonder if that's possible. The original SPC player design was based on a parallel connection, which I would be fine with if I could send the right data out the right port.

Don't know if you've seen this, an APU Arduino shield-
http://www.caitsith2.com/snes/apu.htm
You need to desolder the socket on the SNES main board, to mount the APU. You can either use it on an Arduino or standalone with a PC Parallel port. I bought a board a couple years back, so check with caitsith if he still has any on hand. Of course at his site are the Eagle files so you could send them to OSH Park and sell the two extra.
   Also saw that he has some new APU designs on OSH Park. They look like they incorporate the AVR on the board, so it's a single board design. The boards are for just the APU chips, from the newer SNES without the Can; desolder the chip and move to the new board.

He hasn't posted any info on his site about these but there is a Github link on the OSH pages, so they may still be experimental (?) Last design was posted Dec 23
  My stuff is still sitting in a box waiting for some love. Haven't setup the softwares :\ That tracker looks interesting, if you dig up more info would like to hear.

Yup, I was referring to CaitSith's project in my last paragraph. He was working on an SD-card based SPC player last I check on gitHub.
I don't really want to desolder the connector from the boar, but if I must...Looking at my "can APU" the connector may be removable by force, not solder. On the back side of the PCB, the pins are not staggered. It looks like a common 2-row, 2mm spacing.

...I couldn't force it off.

I'll check those newer designs of his.

Oh! You're talking about a non-intrusive option. I like that a lot, but link cables are difficult to come by for sacrifice.
What about a custom cart that has a micro USB cable on the top. The cart can map a special memory address to store the data in the button flag registers. :shrug:

Along the same lines, I made this a few years back - but then once you put one of these boards in I guess you're really using something other than the GameBoy itself...

Thats pretty sweet. And I know for sure that there are NES to USB kits, so taking it one step further...

And Im sure there are hundreds of public arduino sketches for usb-button dongles.

A video of the test rom in action was posted at nesdev, linked above.

You're saying that these could be researched to make audio emulation more accurate?
What does this mean:
"allow reading the current PCM samples of each of the 4 APU channels in real time"

These two pulse waves and noise are not samples, are they? Noise is created with a feedback register, or so I thought.
Are the registers present in all CPU revisions?
These registers are read-only?

Just came across this. This is pretty big news imo. Could these registers be used in applications other than visual?

I think if you need more room than LittleFM offers, you need to be backing up your cart more often. For you own sake.
Hell, there is even an application to back up your sav's to  your phone.

Original post

They will soon be available to purchase. You can put whatever 8KByte ROM you want on it!

The board is a meer 1.05 inches deep and has notches for easy removal or mounting (granted a shell is designed). Measuring my own commodore, a board of 1.1875 inches would be flush with the chassis. Also has optional reset switch as suggested by catskull.

My main concern was supporting as many proms, eproms and eeproms as I could since too many are no longer made, but easy to find.
supported...
28F010, 28F020, 28F040,
29F010, 29F020, 29F040,
49F010, 49F020, 49F040
2764, 27128, 27256, 27512
27c64, 27c128, 27c256, 27c512

As well as SF's, GL's, EE's, etc.
Also working on support for 2704, 2708, 2716, and 2732. These will fit, but would require a few rerouted pins.
