I'm very excited about Dave's scans, because the circuits look right and
the date of 1967 would allow for both Richard's experience of building this
at school and for the author to have published as a book. He states the
intention of using the design as a teaching tool. Unfortunately there's no
named credit in the scanned pages (anything in the contents list Dave?).
But we do have "The computer will be on show at the R.S.G.B exhibition."
The one-transistor NOR gate and the toggle-flop design are both as I
remember them. Likewise the fact that it's bit-serial rings a bell.
Dave: can I assume you're happy for me to re-publish some or all of your
scans? I want to clip out at least some diagrams and tables.
[Does this list allow for attachments or MIME emails?]
Fourpence-ha'penny for a diode!

Hi,
I'm interested in what you have found, I'd love it to be an article about
the computer. It's a long time ago and I have only vague memories of
soldering the logic units - some of the older boys got to assemble the
actual machine!
Best regards,

Now found and scanned but due to the state of the paper are scanned in

The article above refers to it continuing into 1968 but the stuff I
have found ends in December 1967
pm me for url as the files are large and cannot handle a download swarm.

Richard, I think I read the book this project was based on - in the
school
library, mid-to-late 70's. I've been looking for it, but my
recollection
is so vague I haven't found it yet. I think it may have kicked off
with
some physical computing based on wood and ball bearings, but anyhow it
worked up to a full serial CPU. My searches have been based on the
recollection that the author was Wilkinson (but maybe Wilkins, Watson,
Wilson, Watkins, Watkinson, ...) and, of course, it might not even
have
starte with W.
How about the magazine wireless World

I do believe I have the set of articles here somewhere
