Amiga Bootselector PCB for a buffered DF0: - DF1: boot selector for the A500 / 2000
This boot selector is really only suitable for an Amiga 2000 if you have a Gotek internal and a normal 3.5 Floppy drive.
For booting an external (DF2:) a PCB for another boot selector is available.
The buffer ensures that the switching from DF0: to DF1: (And vice versa) is not done mechanically, but electronically.
That in turn minimizes the chance that your CIA (8520) will malfunction due to the switch.
A mechanical switch is still used for this, but only to trigger the electronic switch.
