There are at least 10 groups who have proposed a 32 bit extension or larger. This would include 65k, 65000, 65020, 65GZ032 , 65Org32 , 65832 , 65E4 , 65m02 and tentative steps separately from Proxy and I to extend 65CE02. It is apparent that many of the proposals have common themes and they typically ...

I don't want to troll, and this may be 100% genuine, but can anyone vouch for the authenticity of this doc?
The 65E4 spec was provided by former Commodore engineer Frank Hughes. He recently gave me materials that he saved from the old days with the understanding that I would scan and post them ...

... The 68000 did quite well with graphics because of it's flat address space, I haven't read enough of the document to see how it would work with 65E4, but it's addressing is more complex. It's probably a bit late to market for a 16-bit design, already with strong competition from Motorola and ...

It looks like this for me in Chrome. My Epson MX-80 did a better job than that, but I have also seen far worse.
Quite a fascinating device.

Mike has recently unearthed and published a remarkable document: a specification of an MOS chip called the 65E4, intended to be a powerful high level 32 bit MPU successor the 6502. Even, somehow, with backward compatibility for 6502 code. It's a big document - 182 pages! See a few snippets below ...
