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.
An example IOMMU is the graphics address remapping table (GART) used by AGP and PCI Express graphics cards on Intel Architecture and AMD computers. On the x86 architecture, prior to splitting the functionality of northbridge and southbridge between the CPU and Platform Controller Hub (PCH), I/O virtualization was not performed by the CPU but ...
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.
In the renaming stage, every architectural register referenced (for read or write) is looked up in an architecturally-indexed remap file. This file returns a tag and a ready bit. The tag is non-ready if there is a queued instruction which will write to it that has not yet executed.

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 11/34 supports up to 256 kB of Unibus memory. The PDP–11/34a (1978) [15] supports a fast floating-point option, and the 11/34c (same year) supported a cache memory option. PDP–11/60 – 1977. [15] A PDP–11 with user-writable microcontrol store; this was designed by another team led by Jim O'Loughlin. PDP–11/44 – 1979. [15]
