| Came across this during some random search - http://homepage.mac.com/jorgechamorro/a2things/PDFs/65xxx.txt I've never heard of the 6516 mentioned before (as a development pursuit or otherwise). The 6516 sounds pretty impressive from what's mentioned in that article. the original article the link ab... |

| ... Even the 65816's bank boundaries are gone. ⋅ Since the data bus is 32-bit, there will not be separate 8-, 16-, and 32-bit modes like the 65832 had. The what-about's are addressed in earlier posts, like that 32-bit-only is not a problem for 8-bit I/O ASCII data. It would not have an emulation ... |

| I was digging around in a binder the other day, and I found my old 65832 docs from March 1990. It's a straightforward 32-bit extension of the 65816, and has an E16 bit (behind the V bit) for 65816 emulation. I'm rather glad it wasn't built, because it wasn't ... |
