Yes it was in the UK. From what I remember it looked manufactured, but it
could have been built from a kit I suppose. If you could scan just the
picture from that magazine that'd be great.
Replying to other kind people who have responded, It wasn't either of the
two machines you have posted links to - MiniVac 601 or Heathkit EC-1, but it
looked a bit like the Heathkit one except the wiring grid was smaller and in
the top left (I think), and there was a telephone dial - exactly the same as
that found on old telephones - on the right hand side too (can't remember
what must have been on the left!).
Thanks for everyone's help anyway,
cheers,
paul

This is going to be rather difficult I think. In 1977
when I first went to
high school, we had a visiting computer science teacher (the school didn't
own it's own computer). He used to come in with a PET mostly, but one day
he
couldn't bring the PET so came in with this old
machine which was roughly
cubic, each side about 2 foot. On the front it had a wiring panel where
you
had to plug in patch leads, and a rotary dial like on
old telephones which
was used to dial the numbers in. I don't remember how it displayed its
results.
Interesting, I presume from your email address that this was in the UK.
The first thing that came to mind was the Wireless World computer, this
was a construction project published in the Aug thru Dec 1967 issues of
that magazine. (on my long list of things I to scan someday).
The 'computer' had an 8 bit word and a 3 word memory and an accumulator.
It could perform various arithemetic operations. The actual published
articles do not show a telephone dial but ISTR some mention of
extensions based on telephone equipment : dials and strowger switches.
The size and propotions seem to fit, the published design had switches
and lights on the front panel and no plug-board.
Do you recollect if the machine was homebrewed or manufactured?
