It's the 32-bit RISC 6502 compatible I am making. Actually, the CPU itself is almost done (it has been for a while now :); it is the I/O that is taking me more time than I expected. Quite some things seem to run alright in simulation; I haven't tried it on the real hardware as of yet, because of the I/O functions that I still need to make. As a matter of fact, I have taken the board that I made two years ago off the shelf and blew the dust off, and it is running inside a C=64 now, with an 8-bit 6502 CPU that I made in VHDL even longer ago. If you want, you could use that platform to do the MMU thing that you invented... Or have a bit of patience and use the MMU of the GZ032. In that MMU you can also control the caching for each page (and address more than just 16MB). Gideon Message was sent through the cbm-hackers mailing list
