PDP‑11/Hack de Luxe is an Eurocard sized Single Board Computer using a DCJ11 which implements the basic features of a breadboard PDP‑11/Hack with an expansion slot that allows for further enhancement up to a fully functional PDP‑11 running RT‑11.
Read moreA PDP-11 is more fun to use, when you have more memory, especially when your system supports 22-bit addressing. Therefore I decided to build my own PDP-11 Q-Bus memory board.
Read moreThis is a short resume about my Plessey Peripherals PDP‑11. Or let’s say about the remains of the system which for a long time was just a play ground and today I could revive it as a fully functional PDP‑11. Even only the core is of the original system, adding new components for the surround still let’s you experience the real look and feel of a small PDP‑11.

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.
