I am fully aware of those facts and they do not contradict anything I have
said or implied.

You don't say!

> ACE - 1955

the NPL ACE did not exist in 1955. Perhaps you confuse it with the Pilot
ACE,
which did not have an Algol compiler.

You seem remarkably keen to pick a fight over something I did not say.

As it happens I have personal contact with Brian Randell, one of the
authors of DEUCE/KDF9 Algol and am well aware of its history.

Had you investigated my website instead of jumping to peevish conclusions, 
you would have found a DEUCE Algol document dated 1963, some months 
before the first KDF9 was delivered.

This is my last communication on the subject, as I refuse to stroke your
ego with any further attention. 

Anyone looking for accurate information on KDF9 Algol, approved by one of
its authors, can consult my website.
