The PDP-6, short for Programmed Data Processor model 6, is a computer developed by Digital Equipment Corporation (DEC) during 1963 and first delivered in the summer of 1964. [1][a] It was an expansion of DEC's existing 18-bit systems to use a 36-bit data word, which was at that time a common word size for large machines like IBM mainframes.

pdp-6，由迪吉多公司在1963年發展的迷你電腦。是pdp系列產品之一，它的後繼機種為pdp-10，這兩種機型使用的指令集幾乎完全相同。

在 PDP-1 推出之后 DEC 没有停歇，用今天的话来说就是疯狂刷机型，1960 年 PDP-3，1962年 PDP-4，1963 年 PDP-5，1964 年 PDP-7。 这其中有的销售不佳，如 PDP-4 就非常惨淡，而 PDP-6 项目则直接因为市场反映不佳而直接搁浅；但继续走小型化之路的 PDP-5 却非常受市场欢迎。 于是，秉承着 PDP-5 的理念，在此基础上进行大幅度改进的 PDP-8 被刷出来了。

The PDP-6 was effectively the first model of the PDP-10; they are (mostly) object code compatible. It was built out of System Modules, DEC's predecessor to the FLIP CHIP module series (out of which the first PDP-10, the KA10, was built). It featured 36-bit words, at the time effectively the standard for machines used for scientific computing.

2004年8月15日 · The PDP-6 was designed as a new kind of mainframe, to be used for both timesharing and real-time laboratory applications, with straightforward interfacing capability. It was the first of what might be called a "personal" mainframe. It also was the first commercial computer available with software for timesharing applications.

2012年8月8日 · The PDP-6 meets these criteria with a number of hardware and software features. Common to all is a modularity that permits PDP-6 systems to be specified for almost any application, to grow in size as requirements increase, and to be able to control new peripheral equipment as it is developed and made available.

Primary human readable PDP-6 material from the 1960s. Some secondary PDP-6 annotation, discussions and Talmudic scholarship will be tolerated for a while.

PDP-6/10 Instruction set. The PDP-6/10 instruction set may seem daunting at first, but it is actually very regular and easy to understand. You can even completely memorize it without too much effort if you understand how it works. You can find a description of the PDP-6/10 instruction here for the PDP-6 , KA10 .
