I've promised someone at Elektor a notice when the SC/MP Emulator was ready,
so I can also ask the a reprint of this TTL-system and posibly even get the
permission to put it up on my site. Or ask them to put it up themself ;=)
By the way .......
I know the url of the dutch Elektor site: http://www.elektuur.nl
(but don't know if they have versions of their site for other languages )
If it wasn't for the existance of this great Electronics magazine I would
never have ended up way deep into computers. I learned a lot from them
so credit is due!

But does
anyone remembers the computer Elektuur published before that, in
1974 ?
I don't think there was a UK version of Elektor back then, was there? If
there was, I never saw it :-(.
That computer sounds like fun, though. There have been very few 'build
your own CPU' projects in maagazines, unfortunately...
What I do remember, (and have all the articles for) is the (UK) Practical
Electronics Digi-Cal project, from 1972. This was a 4 function desktop
calculator built from (mostly) TTL. IIRC, the registers, adder,
multiplication counter, etc were on plug-in cards and there was a large
piece of stripboard in the bottom of the machine for a diode-matrix
control store. So although it wasn't a computer (not user-programmable),
it came close IMHO.
It's one of those things I've always wanted to build, but getting all the
chips would be very expensive, and I think I could probably build a small
general purpose CPU with the same parts (which would probably be more
fun). Oh, if anyone suggests using the 4-letter F-word [1], I will LART them.
[1] FPGA, of course. Why, what did you think I meant? :-)
