The MX15-A Memory Bus Multiplexer is a PDP-15 sub-system which has three memory bus input ports, and one output port, which can be connected to 32K words of core main memory. PDP-15 CPU's and DMA peripherals can be connected to the input ports. A PDP-15 CPU can be connected to up to four MX15-A's; thus, the total memory provided to it can be up to 128K words.
The MX15-A allows the input ports access to the main memory on a priority basis; port 1 has the highest priority, and port 3 has the lowest.
