''AMRAM2'' is a ROM board from [[Silicon Systems]].
When writing data only bit 0 of the data is significant all other bits are ignored.
If bit 0 is 1, then AMRAM is activated and writing to it's RAM is possible. If bit is 0, then AMRAM is not active.
The ROM select is decoded in the normal way: Bit 13=0, all other bits are ignored.
In addition the ROM select IDs are decoded fully, there is no repeat accross the 256 ROM range. The ROMs only exist in their designated slots (i.e. 1 only exists at position 1 and no others).
