	BRLESC I
		The control of BRLESC consisted of many units, each controlling their associated process, but all regulated by a master control center, which had a pre-determined time priority system and which prohibited the initiation of new events in any of the various concurrent trunks should there be some conflict in the use of information or units.
		For example, if two tape trunks were to use the same tape handler for different purposes at the same time, the trunk which received the first request got priority to use the handler and the other trunk had to wait until the first had finished using the handler.
		BRLESC was provided with a parity system to check word transfers as they passed through the memory and to or from tapes and drums.

	BRLESC - Wikipedia, the free encyclopedia
		BRLESC was designed primarily for scientific and military tasks requiring high precision and high computational speed, such as ballistics problems, army logistical problems, and weapons systems evaluations.
		It contained 1727 vacuum tubes and 853 transistors and had a memory of 4096 72-bit words.
		BRLESC employed punch cards, magnetic tape, and a magnetic drum as input-output devices, which could be operated simultaneously.

		BRLESC was scheduled to be in operation by the end of 1961.
		The BRLESC is an general purpose, electronic, digital computer with parallel arithmetic mode and synchronous timing.

		It also discusses the use of computers for solving gunnery problems, and provides a "family tree" of early computers.
		Few inventions have had as big an impact on our civilization as the computer, and all modern computers are descended from ENIAC, EDVAC, ORDVAC, and BRLESC -- all of which were conceived of and built to address pressing Army needs.
		To give credit to the highly skilled and dedicated military and civilian scientists and other workers through whose efforts, together with their counterparts in the private sector, met and solved a great national defense challenge while at the same time giving birth to a technology which would change the world.

	ARL/BRL Since Eniac
		BRLESC went on-line in 1962, and tests showed that it was two- to eight-times faster than commercial systems.
		BRLESC II was a solid-state digital computer designed to be 200 times faster than the ORDVAC it replaced in 1967.
		The integrated circuits for BRLESC II were produced under an industrial contract, but BRL employees did all the logic design, back-panel wiring, and assembly.

		The Army's Ballistic Research Laboratories is a prime example of the military's former forefront in the computer industry.
		These laboratories were first in many areas such as operating ENIAC, EDVAC, ORDVAC, BRLESC, BRLESC II, developed FORAST, designed one of the first FORTRAN compilers for a non-IBM system, and helped to developed ARPANET.
		For those who do not know what these acronyms are, this is the basic progression of the first super-computers into the Internet.

		This reduced the number of shifts required, which was very important on a very early vacuum-tube computer, although the maximum possible loss of precision was rather drastic on a machine with a 48-bit word length.
		The BRLESC computer, with a 69-bit word length, used a base-16 exponent, thus remaining within the bounds of convention.

		Implemented the SAM-C monte carlo nuclear transport code on the BRLESC computer, applying nuclear and radiation shielding expertise to determine the survivability of ground combat systems in a nuclear battlefield environment.
		Hardware I have used included mainframes (BRLESC, CDC, IBM), workstations (Sun, HP, SGI), and PCs as well as special purpose systems such as telemetry systems and network cards; I have had hands-on training in the design, application, and programming of micro-processors (such as those used in embedded systems).
		I personally have designed and installed ("pulled the wire," hooked them to multiplexers, and debugged their installation) a terminal network while at AMSAA.

		Eniac remained at the Maryland facility, then known as the Ballistic Research Laboratory, into the early 1950s.
		The lab later commissioned several custom-built computers, including BRLESC-I, which in 1962 was the fastest in the world.
		In the late 1970s, production models began to come from Control Data Corp. and later Cray Research Inc., Nietubicz said.
