Thank you very much Tony.
The person that wrote to me said "I would recognize this
computer anywhere.", refering to the picture on my web site:

I have made a guess from date codes that it was built with
1971 parts by Physical & Electronic Laboratories Ltd. But the
writer says that the computer was designed by D. Bollen
"from top to bottom" and was featured in this series of
articles. I wonder if the computer might be a magazine
project kit. That would be a very interesting development.
