@Anemos: the glass bulb diode is also known as Germanium diode. Most common unit is the 1N60, which have a normal voltage drop of 0.3V.

Also Germanium units are known by they current leak on reversed voltage, but on the Amiga case this current is negligible.

But on the low current circuit of Amiga RTC the drop is only around 0.15 (checked with my multimeter).

A Schottky diode will "improve" the voltage by less than 0.1V compared to a Germanium unit. But at a cost: schottky diodes tend to cost a bit...
