The new Elliott 503 computer, companion to the famous 803, is probably the greatest computer of its class ever produced.

The 503 is remarkably fast, extremely versatile, and surprisingly easy to operate. It starts where the high successful 803 leaves off. It's a computer to unlock doors, chart new continents, discover new planets of thoughts.

The first British computer to incorporate ALGOL
ALGOL has been developed to simplify programme preparation and aims to supply the obvious demand for an internationally acceptable computer language. A basic computer language like ALGOL is not only practical but necessary for the computer of tomorrow - and even today. The first British designed computer equipped to use ALGOL is the Elliott 503.

But this is only one of the 503's many advantages which are unique among medium sized computers. Here, briefly, are some of its other special features.

100,000 arithmetic operations per second. Compatibility with the popular 803. Large magnetic core store. Auxiliary magnetic core storage of almost unlimited capacity. Direct connection of high-speed input and output equipment. Time-sharing of peripheral data transfers.

Isn't it time you found out more about the Elliott 503?

Two Elliott computers - the 503 and the 803. Price range: £20,000 to £200,000. Between them, they cover the chief scientific and industrial applications. First, the 503. Built to meet the increasing demand for high speed computers for use in research and development. The 503 has no competitor as a replacement for older/smaller/slower installations. And its low price puts it within reach of organisations that now use computing centres. The National-Elliott 803 is the smaller machine, from which the 503 has been developed. With over 120 already delivered, the 803 is far and away the most successful British computer. The two systems are compatible - programs written for the 803 can be used on the 503. Elliott's provide Autocode, ALGOL 60, and over a hundred library programs - and an active users' association provides for exchanges of application programs. If you're thinking about a computer, call early on Elliott's who can do much of your thinking for you.

Elliott's building at Elstree Way

The address field in both transcriptions above links to Google Maps with Streetview
Thanks to Andrew Gabriel's post to alt.folklore.computers who identified the correct building and noted the following:

The address links to google maps, but it's pointing at the wrong building. 
There's no feedback link, but the correct Elliotts building is (or was): 
If you look carefully at the end of the building, you can see a 
large dirty mark on the brickwork where the "GEC" logo used to be 
from about 1970 - 2000! 

The building is shaped as a big 'E' for 'Elliotts': 

It became a GEC building when Elliotts was taken over by GEC. 
The building was eventually sold and rented out to many smaller 
companies as the Elstree Business Centre, although some small 
former bits of GEC, Marconi, and Elliotts remained in there. Last 
time I drove past the rear of it (some time ago), it looked rather 
derelict and was empty (at the rear, at least). When I worked 
there in the 1980s and 1990s, the Elliott Automation library 
still existed. I don't think any new books had been bought for 
it since GEC took over though - it was obviously good research 
libarary at one time, but there was nothing in there published 
after about 1965;-) 

Elliotts (and GEC) also owned the next site along, which consisted 
of many single storey prefabricated "huts", probably from war time 
(and still looks like it does on google maps, although there's no 
streetcar view along that road). In the mid 1990's, GEC Hirst Research 
moved in to these when GEC sold their Wembley site, although GEC 
disbanded Hirst Research (and Marconi Research) a couple of years
