RCX_16MB_RAM memory board is intended for eLeMeNt ZX, to expand RetroCoreX 4MB memory to 20MB.

Key upgrade features:

• 20MB  Fast SRAM
• SoundDMA, FastDMA, DMA and CPU can use it

Note: not for MB03+ Slim. 

Note2: Due to limited space under the keyboard, the RCX_16MB_RAM upgrade cannot be installed into eLeMeNt ZX board mounted inside original ZX Spectrum +2 / +2A / +3 cases. RCX_16MB_RAM is fully suitable for builds using the TinyCase, where there is enough internal space for the RetroCoreX board, RCX_16MB_RAM and adapter.
