Anyone knows how the AlfaData kickstart switcher works?

Hi everyone,

I have this kickstart switcher that I would like to use in my Amiga 500.

I know how the switcher must be installed in the machine, but since I haven't got the manual for it, I don't know how to operate it :-(

I have a Kickstart1.3 chip and a Kickstart2.0 chip installed in the switcher. I have tried putting a wired switch on the kickstart switcher, but I can only boot with Kickstart2.0 and not Kickstart1.3 even if I switch the order of the ROMs. Maybe I don't know how the switcher must be installed in my Amiga afterall....

According to BBoAH I should be able to switch the ROMs using the keyboard, can anyone tell me how?

I have the non-plus version still in the original package and there's no manual.  The instructions on the back simply say install either 1.2/1.3 roms in the two rom sockets and plug the ribbon cable into the 500's rom socket.  You use the switch to toggle to the preferred kickstart before turning the machine on.  I could never get it to work with a 2.0 rom so never used it.

I had a different switcher but on that you held down the reset group of keys for a certain ammount of time and it switched.
