Worcester's gas, oil and LPG ranges consist of regular boilers, combination boilers and system boilers; these are wall-hung, floor-standing or externally sited. Worcester's solar water heating range was released in 2005, with the ground source heat pump range being released in 2007 and the air source heat pump range being released in 2008.
An advertisement for the "Sun-Series ACS8000-6" sold under Altos' own brand appeared in the November 1979 issue of Byte, and indeed promised to support up to four users by means of its AMEX kernel, and supporting a maximum system memory of 208 KB. [7] The ACS 8000 could run at least three multi-user operating systems: Altos' own AMEX, Oasis, or ...
A farm on Shrewsbury Street in Holden, about 5 miles (8.0 km) north of the center of Worcester, was purchased in 1934. Construction of a new transmitting facility was begun in 1935. On February 2, 1937, WTAG began transmitting with a power of 1000 watts using a three tower directional antenna system. This transmitter site has been in continuous ...
The company has designed and manufactured pressure/space suits and life support systems for NASA and U.S. Air Force. [2] It developed partial pressure suits for NASA's Bell X-1 rocket-powered research aircraft in the 1940s, and full pressure suits for the D558-2 and North American X-15 research aircraft in the 1950s.
The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental DDA40X. Peak production of the SD40-2 was in the mid-1970s. Sales of the SD40-2 began to diminish after 1981 due to the oil crisis, increased competition from GE's Dash-7 series and the introduction of the EMD SD50 , which ...
The Burroughs Large Systems Group produced a family of large 48-bit mainframes using stack machine instruction sets with dense syllables. [NB 1] The first machine in the family was the B5000 in 1961, which was optimized for compiling ALGOL 60 programs extremely well, using single-pass compilers. The B5000 evolved into the B5500 (disk rather ...
After years of cost reduction, the average US price per watt was between $2.51 to $3.31 in 2020 for 10 kW systems, [89] and $1.05/W for utility systems. [90] Another type of distributed generation implemented by a utility company was the world's first grid-connected pole-attached solar panels of Public Service Enterprise Group in New Jersey.
The 2nd version of the 8000, a dual-CPU system released 1978, supported up to about 1GB of hard disk. The Geac 9000 (or Concept 9000) was introduced in the 1980s. This was a very different machine from the previous ones.
