First soviet CPU K580IK80 (i8080 clone) was born in 1979 in Kiev.
Is it the very first CPU manufactured in continental Europe?

I think first European clones were 8008s chips.
IMHO the Siemens SAB8008 (made in West Germany) and the MME U808D (East Germany) were the first CPUs manufactured in Europe. |

my oldest european 80XX chip is SAB8080AC mfd 7636

Manufactoring of FWE U808D startet in 1977.

I downloaded this document (yes, I did pay for it, at £3.50 per page!)
http://www.iop.org/EJ/article/0305-4624/8/5/I02/ptv8i5p190.pdf
The article was published in 1977 but frustratingly it doesn't nail down any specific release dates. The only clues are:
| Quote: | The story probably starts with the introduction by
the company in 1971 of a new method for making
integrated circuits, called collector diffusion isolation
(CDI)" |
| Quote: | Emergence of the microprocessor
When the properties of CDI became more widely
known, the question asked by our Technical Director
(Mr J R Pickin) was ’Is it possible to produce a
computer on a chip using CDI?’ The term microprocessor
had not been coined at this time. After a
survey of the computing requirements of the various
Ferranti divisions using computers it was concluded
that such a scheme was possible and this was the
start of F100-L. At the same time that the survey
was being undertaken we were also asked by the
Ministry of Defence if we would be interested in
developing a computer on a chip for military applications.
The attraction of CDI for this application was
that, unlike some of the contemporary MOST processes,
it was ideally suited for the military operating
temperature range of - 55°C to + 125°C. |
| Quote: |
The final part of the story concerns processing yields.
When CDI was introduced in 1970 it was felt that it
had the potential to provide high yields on complex
integrated circuits. The ultimate proof of this came
with the successful development of F100-L. It took
a major yield-enhancement exercise however to |
and
| Quote: | Final developments are now taking
place directed towards the release of volume production
chips to full design specification within a
short time. |
So... who knows?! I might try to ask the author, or somebody involved to ascertain the timeline. Anyway it's an interesting article; and I will bundle it with all of my sales of F100L processors.
UPDATE
The Museum of Science and Industry (Manchester, UK) which houses the Ferranti Collection lists on it's timeline 1976 as the introduction of the F100-L (http://www.msim.org.uk/collections/collections-online/ferranti-collection/timeline)
I might visit them and take a look at the collection (they are only an hour away from where I live).
I will look into this further, but Indian food is now the order of the day! |

Hi,
probably database access at a Techuniversity would help with this Recherche!
