1104 – Ausbausystem: Übungs Ausbausystem (Expansion Training System)
The 1104 model is an extension to the Elementary Übungs System model (1102) and explores a variety of different experiments relating to general electronics. The 1104 model is packaged in a sturdy black carrying case but is shipped only with the 1103 instruction manual which covers 64 experiments.
The Electronics AG model (1103) combines the 1102 and 1104 model trays which provide all the blocks necessary to conduct the experiments profiled in the 1102 and 1103 instruction manuals. The 1103 combination model ships in a large black or blue case.
The graphic below shows the 1102 layout in the left panel and the 1104 layout in the right panel. Together they form the 1103 model.
When I purchased the Special Laboratory model (1210), I only received the 1102 and 1103 instruction manuals. There does not appear to be an individual 1104 instruction manual.
