The RAM and ROM blocks of memory can be mapped in a variety of ways with a minimal
memory block size of 8K. The EPROMs/EEPROMs may be configured to occupy low
memory, high memory, or start at low memory and then relocate to high memory upon
initialization by appropriate jumper selections. The GALs may be reprogram by the user, or
RIGEL Corporation, to support the different memory maps. Please call Rigel Corporation if
more information about user designed memory maps is needed.
