Bootselector is needed so that the external drive (eg Gotek) acts as DF0, which ensures compatibility of all games and programs.
This device switches DF0 and DF1 signals electronically using a multiplexer, and it works with Amiga 500.
The most important advantages of this solution:
– The switched signals remain near the CIA, not going to a remote switch, so thay are not susceptible to interference.
– The switch can be moved anywhere, and only a single cable can be used.
– Switching is effected by one ground signal given on the bootselector pin.
– By separating the CIA signals and controlling the multiplexer, the CIA is protected against damage in case of short circuits on the cable or switch. Nothing happen with CIA or multiplexer, even in that case.
– You can use any switch, or jumper, or control the pin electronically with some kind of control device etc.
How it works?
When the pins (switch) are disconnected, the Amiga works as standard: the internal floppy disk drive works as DF0 and the external floppy disk drive works as DF1. When we put on a jumper (or connect it with a switch), the external FDD becomes DF0 while the internal FDD doesn’t work.
– Bootselector device
– Cable with a switch
The cable has a length of about 35cm, which allows you to place the switch anywhere on the enclosure or pull it out through the trapdoor etc.
We are highly recommending to use this device especially with Gotek as external drive or any other external drive.
