| Parameter No. | Bit / Group | Function Description | | :--- | :--- | :--- | | | Bit 0 | Program Storage 640m : Activates a specific memory module size (often 640 meters of paper tape equivalent). | | 9921.1 – 9921.4 | Bits 1-4 | Varying Storage Sizes : Correspond to different memory capacities (320m, 160m, 80m, 40m). Often only one of these is set, depending on the DRAM module installed. | | 9923.7 | Bit 7 | Background Editing : Allows the operator to edit one program while another is currently running (machining). This is a significant productivity boost. | | 9926.3–9926.4 | Bits 3-4 | Tool Offsets Expansion : Expands the tool offset memory from the standard amount to 64 or 99 entries respectively. |
