Its architecture was an almost identical version of the earlier PDP-6 architecture, sharing the same [|36-bit] word length and slightly extending the instruction set with improved hardware implementation. PDP-10 had 18-bit word addresses, in a so called supervisor mode, instruction addresses correspond directly to physical memory, In user mode, addresses are translated to physical memory. There are 16 general-purpose, 36-bit registers.

The PDP-10 was the foundation of the DECsystem-10 and the [|DECSYSTEM-20] and ran a variety of operating systems including [|TOPS-10], [|ITS], [|WAITS], [|TYMCOM-X], [|TENEX], and [|TOPS-20]. TOPS-10 was the first widely used [|timesharing system]. || toc =Chess Programs=
