The SuperMem board is an addition to the TRS-80 Model 1k that provides 512KB of Banked SRAM (mostly) compatible with the SuperMem 512 for the Model 1
This is implemented as a small board that replaces the 128 Kbyte SRAM chip on the main board, and contains the 512KB SRAM and the necessary bank control logic.
NOTE: THIS IS FOR V2 OF THE MODEL 1K
