/* Used components: */
* 1x connector for the [[Connector:Expansion_port|expansion port]]
Note: The 74LS20, 74LS04, 74LS32 are the smaller logic symbols in the schematic.
 
Note 2: The 74LS138 splits the address space to four regions (which is total nonsense), the 74LS20 is then merging them back to a single region (which is undoing that nonsense). There seems to be no real reason for doing that - except maybe to avoid legal copyright problems (claiming something like "no this isn't a unlicensed remake of Schneider's schematic, our schematic is doing total nonsense, it's has absolutely nothing to do with Schneider's hardware").
