* -12V DC - needed for the [[Schneiderware V/24 interface]] only
* +24V DC - not used (was intended for the EPROM Burner, but when the EPROM burner was released, it contained a 5V-to-25V converter, and thus didn't need the +24V anymore)
Aside from the components on the PCB, one does also need a transformator, which isn't shown on the photos. Despite of being a very important component, the DIY article contained only few side-notes on the transformator. The thing must provide a number of AC voltages, and it might be difficult to find a matching transformator (one could get one from the magazine via mail-order, but it wasn't cheap).
== Connection Caution ==
'''Caution''' - The supply uses the same type of 2x32 pin connector as the other Schneiderware boards, however, the supply is '''NOT''' intended to be plugged into the [[ECB Bus]] sockets, instead, it should be wired to the 7 soldering points on the [[Schneiderware Basisplatine]].
== Alternate Versions ==
There seem to have been one or two alternate versions:
* The photo in the magazine showed a different PCB with giant cooling plate, which won't fit on the DIY layout. That photo may have been a dummy/prototype.
* The magazine later released a correction on their letters page which recommended to replace the 5K6 and 10K resistors on the L200 voltage converter - it sounded perfectly reasonable - except that, the DIY project doesn't contain any of that components. The correction (if it wasn't total nonsense) implies that the magazine shipped different PCBs to some people via their mail-order service.
