摘要： A memory expansion board capable of holding up to 16 Mbytes of memory devices, using primarily 1 Mbit chips, in 2 Mbyte module increments, on a single IBM PC/AT compatible size board. The circuit board is so designed that when the memory expansion board is populated by modules and placed in a computer system it does not interfere with any of the other expansion slots within the computer system, all of the expansion slots being normally spaced apart. The memory expansion board also includes a means of protecting the memory expansion board and modules from damage due to misalignment when inserting the board and/or modules. When certain of the modules are inserted rotated 180 degrees the circuit board cannot be properly installed in the system board because of physical interference. Lastly, the memory expansion board includes a means for providing reduced length addressing memory lines to memory devices appearing on opposite sides of a circuit board.

摘要： A voltage regulation steering circuit reads a voltage input code from a device and detects a set of predetermined conditions for gradually counting an output voltage code. Depending upon the set of predetermined conditions, the steering circuit either gradually counts the output voltage code from a predetermined initial voltage code to the voltage input code or gradually counts the output voltage code from the voltage input code to a predetermined low voltage code. As the steering circuit gradually counts from the predetermined initial voltage code, the steering circuit compares the output voltage code to voltage input code until the output voltage code matches the voltage input code. As the steering circuit gradually counts from the voltage input code, the steering circuit compares the output voltage code to the predetermined low voltage code until the voltage output code matches the predetermined low voltage code. The output voltage code is provided from the steering circuit to a voltage controller.
摘要翻译：电压调节转向电路从设备读取电压输入代码，并检测用于逐渐计数输出电压代码的一组预定条件。根据预定条件的集合，转向电路将输出电压代码从预定的初始电压代码逐渐计数到电压输入代码，或者将输出电压代码逐渐从电压输入代码计数到预定的低电压代码。当转向电路从预定的初始电压代码逐渐计数时，转向电路将输出电压代码与电压输入代码进行比较，直到输出电压代码与电压输入代码相匹配。当转向电路从电压输入代码逐渐计数时，转向电路将输出电压代码与预定的低电压代码进行比较，直到电压输出代码与预定的低电压代码相匹配。输出电压代码从转向电路提供给电压控制器。
