The Telefunken machines I mentioned in the other post also were designed with 
ALGOL in mind. Someone once called the TR4 a hardware representation of ALGOL. 
I wouldn't go this far, but indeed there are lots of machine instructions 
inspired by ALGOL logic (and ALGOL compiler's needs). 

I have a short reference of the TR4 instruction set, from 1967. There is also 
one model shown at Deutsches Museum in Munich, and in the library, they have 
many Telefunken system handbooks from the Leibniz Rechenzentrum at the 
university of Munich. I was there some weeks ago to take a look at these 
books (ca. 300). 

I recently learned that Edsger W. Dijkstra (I hope I got the name rihgt) knew 
the TR4 - there was at least one model sold to a university in the 
Netherlands - and that he was very impressed of it. See private 
correspondence of Dijkstra, there is a web page which includes all his 
letters, articles and so on. 

In its time (from 1962 on), the TR4 was for some years the fastest computer 
built in Europe. 

Kind regards
