making internal x68030 compatible module with this project

[sl1pkn07]

hi!

is possible use this project for making an alternative of SH-5be4-M8 x68030 internal module?

greetings

I expect X68030 has a different RAM system due to it being 32bit.

The 68030 can work in a 68000 system with very little work as it has a dynamically resizable bus on a cycle-by-cycle basis. An emulation of an '030 can physically use 8-bit, 16-bit or 32-bit RAM access cycles. The main difficulty in emulating an 030 is that it uses instruction and data caches that make it hard to maintain cache coherency unless disabled to run '000 code. I'm not aware of any cycle-accurate '030 emulations at this time.

This board is a purely combinatorial address decoder in a GAL plus the SRAM chips hooked up to the CPU bus.

If behaves like a 68000 on the bus, it will work.
