I have all (German) Elektor magazines since the first one in 1/1970 until about 12/1998 where the magazine started to become yet another popular blurb gazette with some relation to electronics.
The mentioned "Computer 74" is also in my list; it was an interesting
gadget to learn about TTL logic - an open collector bus, sort of bucket-brigade dynamic memory, a diode-matrix state machine. The machine was 12 bit. Unfortunately, that series ended abruptly after six issues - one would have expected some more functional units.
I could maybe persuaded to scan in the stuff (notably: the schematics are easily understandable for any EE freak, but the text is German - not that I don't have any problems to understand that as well :-) ).
