Kickstart Switcher for the A2000 which allows you to switch between different versions of KickStarts. This Kickstart switcher is unique in some ways, because some versions can actually hold three kickstart chips instead of the usual two. The pcitures here show both the 2 ROM and 3 ROM versions of this device.
Note: The crocodile clip on the pigtail wire must be attached to either pin 11 on the paula chip or pin 41 on the gary chip. This is true for both versions of this device.
Selecting the Boot ROM and the Keyboard Selectable ROM -------------------------------------------------------------- The ROM slot with the round holes is the default boot ROM. The other two are for ROM chips selected with this jumper. Locate the three position jumper on the Multistart II (the one off by itself) that is on the bottom center of the board. By setting the jumper to the position closest to the ROM chips themselves, you can have the far (currently occupied in the image) ROM as the Alternate (keyboard selectable) Boot ROM. By setting the jumper to the other position (the one farther from the ROM chips - current position in image), it will use the center slot for the Alternate Boot ROM. This jumper doesn't effect the fact that the Default (normal) boot ROM will be whatever is in the ROM slot with the round holes. Setting the MultiStart II for Amiga 500 or 2000 ------------------------------------------------ "You need to set the MultiStart II for the computer that you are installing it in. Locate the three position jumper on the MultiStart II board that is on the bottom right side of the board (currently occupied by a green jumper in the image). The default setting (current) is for the A2000." (The other setting is for the A500) (quoted from manual, with my (notes)) "You can optionally install a switch on the two pin header connector (the only remaining jumper block on the board :) on the right side (next to the jumper block with the green jumper on it) of the board if you have three ROMs installed. This will allow you to switch between the two alternate ROMs to use with the keyboard." You use the ctrl-Amiga-Amiga keystroke to reboot normally. But holding for 5+ seconds will boot with the Alternate ROM. In a three ROM setup, another 5+ second hold down of Ctrl-Amiga-Amiga boots to the *next Alternate ROM. Otherwise, it goes back to the Main (default) ROM.
