Thanks for the pointer. Obtained a copy just now from our library archive.

Hmmm, looking at it, it looks to me difficult to rebuild that thing, just
because many of the TTLs used there are now obsolete and hard to get
(this holds for the also mentioned "Computer 74" from Elektor magazine which
I have as well). Examples of such chips are (from the EGO), at a first glance:
        74100, 74381, 74189

Particularly the latter is a problem, as it is also used in the SWTPC 6809
computer. I do know of the AM29701 as a replacement for it, but this is
also a scarce resource (bgmicro). Anyone has still sources (and not
unreasonably expensive) for 74S189 or 74F189?
