The achievments list isn't spaced properly, after the "8:12pm" or other entries that don't have two digits, a space should be entered 'automatically' so the spacing remains the same.

I realize it would probably take a good deal of work, but it would be nice to have some documentation around the structure of the compiler and its execution flow. I would be interested in contributing to fix the bugs I've reported (big thanks for your prompt responses and fixes), but its difficult to understand the current setup without investing a great deal of energy.

The MMU should issue an mmu trap if the instruction clearing the 'mmu trap enable' bit (bit 9 in ssr0) itself causes a trap. The 11/70 documentation clearly describes this behavior.

This is the reason why test 063 of the ekbee1 diagnostics currently fails.

Since the MMU trap mechanism is is only available on 11/45 and 11/70, but not in the J11, it is not used by common operating systems.
