The VAX 4000 Model 400, code-named "Slow-mega", was a distributed server, positioned as a mid-range VAX 4000 system, introduced on 7 July 1992. [6] It used the KA675 CPU module containing a 63 MHz (16 ns) NVAX microprocessor with microcode patch changes to slow it down beyond the cycle scaling, with 128 KB of external tertiary cache.
The VAXstation 4000 Model 90, code named "Cougar", [1] was a further development of the VAXstation 4000 Model 60. Development of the VAXstation 4000 Model 90 began in mid-1991. The workstation used the KA49-A CPU module containing a NVAX microprocessor operating at 74.43 MHz (14 ns cycle time) with a 256 KB external secondary cache. The NVAX ...
Orchid Prodesigner IIs ISA with ET4000AX. The ET4000AX was a major advancement over Tseng Labs' earlier ET3000 SVGA chipset, featuring a new 16-bit host interface controller with deep FIFO buffering and caching capabilities, and an enhanced, variable-width memory interface with support for up to 1MB of memory with a ≈16-bit VRAM or ≈32-bit DRAM memory data bus width.

It began making air compressors , [5] anti-g valves, [6] pressure reducing valves, stop valves and fuel system relief valves. [7] [8] Most well-known British aircraft in the 1950s and 1960s contained their valves and pneumatic equipment. It developed the fuel system for Concorde. [9] [10] Concorde carried around 22,000 gallons of fuel. Concorde ...
RC 4000 was not widely used, but was highly influential, sparking the microkernel concept that dominated operating system research through the 1970s and 1980s. Monitor was created largely by one programmer, Per Brinch Hansen, who worked at Regnecentralen where the RC 4000 was being designed. Leif Svalgaard participated in implementing and ...
