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. The optional ISA/EISA paddleboard solves the DC-690B incompatibility problem with some early PCI mainboards. If installed, connect CN3 to JP4, and set JP4/jumpers 1-4 in the open position.
