 | | The Commodore REU (RAM Expansion Unit) was announced at the same time as the Commodore 128 home computer. |
 | | Although the C128 could access more than 64K of RAM through bank switching, the memory inside the REU could only be accessed by memory-transfers (STORE, LOAD, SWAP, COMPARE) between the main memory and the REU memory, thus, giving an equivalent to a (slow) small memory window. |
 | | Like other add-on products from Commodore International, their relatively small installed base relative to the huge installed base of the Commodore 64 made software developers hesitant to invest much time and effort in supporting it, and the lack of commercial support kept sales lower than they otherwise might have been. |
