MISCELLANEOUS TECHNICAL NOTES |
|
Some versions of this board have two 512KB x 8 DRAM chips mounted in place of Bank 0. In such a case the board will work without additional memory. In all other cases a pair of 256KB, 1MB, or 4MB SIMM modules must be installed in Bank 0 for the board to function. Jumpers JP3 and JP4 are factory-configured - do not alter. |
