CU-MEM Selecta is a 'paged' memory carrier in Eurocard format. The paging concept allows 8-bit microprocessors to overcome the limitations of a 64kB address space.

CU-MEM Selecta provides eight 28-pin memory sockets which may be configured in a variety of ways using an on-board option switch. Its great flexibility derives from an advanced design incorporating the use of PALs (Programmable Logic Arrays).

CU-MEM Selecta is designed for use with the CUBE processor cards including EuroBEEB, EuroCUBE-65, and EuroCUBE-09.
