## Known differences between SimH, 11/70, and w11a
|
|
|
|
### SimH: MMU maintenance mode not implemented
|
|
|
|
The 11/70 has an MMU maintenance mode, actived with `MMR0` bit 8.
|
|
When activated, only destination mode references will be relocated.
|
|
|
|
The SimH does not implement this feature.
|
|
|
|
The xxdp program `ekbee1` uses this feature in test 046.
|
|
This test is modified when executed on w11
|
|
(see [patch](../tools/xxdp/ekbee1_patch_1170.scmd)).
