Released in 1980, TSX-Plus was the successor to TSX, released in 1976. [2] The system was popular in the 1980s. The last version of TSX-Plus had TCP/IP support.. S&H wrote the original TSX because "Spending $25K on a computer that could only support one user bugged" (founder Harry Sanders); the outcome was the initial four-user TSX in 1976.
The PDP-14 was designed to process Boolean equations, usually expressed as “ladder diagrams” and as such had a programmable read-only program memory. Programs were developed using a PDP-8 then tested using a direct connection to the PDP-14. The PDP-14 was put into a check out mode where instructions were provided by the PDP-8.
The J-11 is a microprocessor chip set that implements the PDP-11 instruction set architecture (ISA) jointly developed by Digital Equipment Corporation and Intersil. It was a high-end chip set designed to integrate the performance and features of the PDP-11/70 onto a handful of chips. It was used in the PDP-11/73, PDP-11/83 and Professional 380.
It is the successor to PAL-11 (Program Assembler Loader), an earlier version of the PDP-11 assembly language without macro facilities. MACRO-11 is supported on all DEC PDP-11 operating systems. PDP-11 Unix systems also include an assembler (called "as"), structurally similar to MACRO-11, but with different syntax and fewer features.
The 18-bit PDP-15/40 connected to Massbus peripherals via a PDP-11 front end. An engineering goal was to reduce the need for a new driver per peripheral per operating system per computer family. An engineering goal was to reduce the need for a new driver per peripheral per operating system per computer family.
The M11 was a microcoded implementation of the PDP-11 instruction set done from scratch, Mentec announced, describing it as a processor upgrade board replacement for the M100. [7] It was based around two Texas Instruments TI8832 ALUs and a TI 8818 microsequencer.

The 6100 is a 12-bit CPU that closely emulates the PDP-8 (See PDP-8 for a more complete discussion). It has three primary registers: PC (program counter), 12-bit AC (accumulator), and MQ (Multiplier Quotient). All two-operand instructions read the AC and MQ and write back to the AC.
