It is the Motorola EC030 at 50MHz you got here.
No MMU, but still is a 50MHz 030!
Sorry for hijacking the thread, but what actual difference does an MMU make to an Amiga? I didn't think AmigaOS had any form of memory protection.
I guess if you wanted to run 68k Linux, you'd need one, but if you're running Workbench...?
