 FWIW, in 1972 the UK magazine 'Practical Electronics' published a
 design
 (going over 10 issuses, I have the whole set) for a TTL-based 4-
 function
 desktop calcualtor. Not a computer, sure, but a lot of the
 principles
 were there.
  Those who like to see something special should
check it out : it  
 is a
  two-address machine, no instructions, but
memory-mapped  
 "functional
  units". It even had hardware based multiply
and divide ! 
 I'd love to see that, but my Elektor collections starts at about
 the time
 of the first Elekturscope (and I don't have a complete run since
 then, alas)

 Hah,
 I remember the PE calculator well.  I actually built it, though I
 restructured the boards to match some proto PCBs I had.  To make
 it easier,
 I copied out the articles and bound them together.  I saw that
 binder in the
 last few weeks - may have it here in OC.  I'll look tonight.  It's
 not a
 great copy, but anyone is interested, I'll hit the Xerox at
 Kinko's.  (I
 doubt there's enough interest to be worth scanning.)
 I have all the English editions of Elektor, but they are not easy
 to get to.
 My garage is a solid mass of books and electronics.  When I retire
 nextyear, the top priority is to clean up that mess.  eBay will be
 a full time
 occupation for many many months.  Some of the stuff is spoken for -
 I've
 promised Al K. he can copy anything he wants before I sell it.  I
 shouldprobably donate all the software to the Museum, but I still
 don't feel
 positive about their permanence.

Scan 'em! Scan 'em! I'd forgotten all about the PE Calculator...
