Does anyone know what are the Apple II+ voltage rails MIN and MAX voltage specs for +12V -12V +5V -5V rails. Also what does one typically see with a few cards in the slots, like two floppy disk controller cards and the other typical cards used, if there is such a thing as the typical expected voltage seen in most Apple II's on the Apple II voltage rails? I have one power supply I tested last night putting out -4.85V and another one puts out -5.35V, on the -5V rail with the same 5 cards plugged into the slots. Seems like a rather large variance on the -5V rail for the same load, as my first impression. Is there a written spec for the limits for these voltages on the Apple II rails in a reference book somewhere? Thanks in advance.
