1951: Jay Forrester files a patent application for = the=20 matrix core memory.

Back when computers still weighed hundreds of pounds and were = primarily used=20 by the military, computer memory relied on cathode rays to retrieve = information.=20 But the Navy needed a faster computer that could run flight simulations = in real=20 time.

In stepped a team at the Massachusetts Institute of Technology. Led = by=20 professor Jay Forrester, the researchers developed a three-dimensional = magnetic=20 structure code-named Project=20 Whirlwind.

The structure consisted of a plane made of wires and magnetic rings = called=20 cores. Each ring contained one bit of data. Every bit on the memory = plane could=20 be accessed with a single read-and-write cycle.

In short, magnetic core memory was the first random access memory = that was=20 practical, reliable and relatively high-speed. The time it took to = request and=20 retrieve information from memory was a microsecond =E2=80=94 hundreds of = thousands of=20 times slower than memory today, but nonetheless a magnificent = achievement in the=20 1950s.

=E2=80=9CWhen we were working on this, in a million years we = couldn=E2=80=99t imagine what=20 would happen with memory,=E2=80=9D said Bernard = Widrow, who worked=20 on Project Whirlwind with Forrester, in a 2009 interview with Edison Tech Center.

Forrester applied for a patent on his invention May 11, 1951. Project = Whirlwind stayed active until 1959, though the technology was never used = for a=20 flight simulator.

The original Whirlwind core memory is currently located at the = Charles=20 River Museum of Industry, http://crmi.org/ in Waltham, MA. Unfortunately due = to=20 flooding on Mar 15 (13=E2=80=B3 of water on the main floor of the = museum) they are=20 closed until fall.

The memory about half fills a standard 6=E2=80=B2 rack. The actual = core stack is a=20 cube about 10=E2=80=B3 on a side. Capacity is 2kw (not sure about word = width). The=20 rest of the space is filled with the read/write logic, which includes = a bunch=20 of fist sized octal base tubes. Unlike the memory illustrated above, = its cores=20 appear to be rectangular, and consists of many stacked planes, (3D) = not the=20 plane (2D) that all the commercial memories I have ever seen.

Since most people reading may well have been born after the age of = core,=20 some interesting facts: Core retained its contents with the power off, = (magnets after all) but reading a cell was a destructive operation, = and the=20 data had to be re-written after each read. Some machines allowed the = data to=20 be modified before it was written back, allowing things like = =E2=80=9Cadd this to=20 that, and store the result in that=E2=80=9D without an extra machine = cycle. Assuming=20 that the last read included the rewrite cycle, it would be possible to = read=20 the final data from TX-0 today. (much like surfing that used hard = drive you=20 picked up at the swap meet).

Before the adoption of core memory, machines used rotating drums = and head=20 per track disks, mercury filled acoustic delay lines used as shift = registers,=20 and a CRT tube that stored data on an oil film capacitor that could be = read=20 and written by the electron beam.
