Along the lines of the MOS Tech KIM, the Synertek SYM and Rockwell AIM-65, Elektor Electronics also published their 6502 SBC - The Junior Computer.This was marketed in a kit form. It was basically similar to the KIM but more compact. Software for Junior was also published frequently.

I purchased the Junior PCB in 1993 and made a working kit. Subsequently I modified the same extensively by adding an extension board (MB-Ex) so that I now have a 'Millenium' 65C02 SBC which has an optional I/O compatible to KIM (All KIM programs can be ported)

Any Junior Computer enthusiasts out there to share ideas?
