FREMO:87 Standards
To achieve a maximum of compatibility for trouble-free operation at FREMO:87 meetings some standards are obligatory.
All FREMO:87 modules must be compatible under mechanical and electrical aspects.
Otherwise it wouldn't be possible to create a greater or lesser extended arrangement of modules that is operative.
The Fremo:87 standards written by Udo Böhnlein are also compatible to the H0pur standards written by Willy Kosak and the proto:87 standards.
As written the standards are obligatory for any member. On the other hand other members made advanced experience and wrote it down as additional advice in the 'Fremo:87 Modulbauhandbuch'.
