Q-Bus PDP-11 Memory

PDP-11 Q-Bus Memory

A PDP-11 is more fun to use, when you have more memory, especially when your system supports 22-bit addressing. This article is about the first memory card I have built for Q-Bus systems. This is a very simple Memory Card which uses 1M x 16 bit SRAM. It supports one or two SRAM for a total of either 2Mbyte or 4Mbyte of RAM.
