| I've only seen one other like this, which makes me wonder, how common are they? Does anyone else even know about them? |

| Yep, my chip, didn't find it on eBay. Been trying to find one for years, and then just happened to stumble across it. |

| It came in a very rare computer from the 1970s. It was a kit though, so not likely that similar computers would also have this chip. |

I had a chip very similar to this, only it was a 6504 made by Synertek, also in 1976. The 6504 is a pin-reduced version in a 28 pin DIP but the die is nearly identical to the 6502. I gave it to the visual6502.org guys to depackage for some die shots. You can see the chip their page. I also supplied the other two ceramic MOS 6504's shown on it:
http://visual6502.org/images/pages/MOS_6504_die_shots.html
I'm very curious if the Synertek die is any different from the MOS one.
One of the MOS 6504's I sent them is dated 1975. I have about 20 or so more of these 6504's made in 75/76 sitting on factory antistat carriers along with 20 or 30 MOS 6532's dated 75/76 also. I got them from an electronics class that stopped teaching awhile back. (also got a bunch of 4003's and 4002's, but alas no 4001's or 4004's). |

Yep, that one was installed in an Apple 1, which was how I found out they existed, but I had never seen another. I had been hunting for one for a few years after seeing that one. I believe they are extremely rare making the MOS MCS 6502 look common. In fact, I know of many more 6501's than this one. |
