Hi.
I am doing a cleanup/recap/drive maintenance to my A1000. While there, I am hoping to install a DF0/DF1 selector (I found these a nice addition in my A500 with an exernal HxC drive). The internal drive in my A1000 is somewhat temperamental, not to mention very loud.
My A1000 is an early PAL unit with the daughterboard. In this board, which one of the CIA chips is the one controlling the floppies, ie. to which the selector would attach to? On my board they are marked U6N and U6P.
I have one more of these (https://www.ebay.co.uk/itm/283468629873) selectors which I used in my A500. If the correct CIA in A1000 is U6N (further from the 68000) it won't fit due to the daughterboard pins next to it. If it's the U6P it *might* fit there.
In case the selector linked above won't fit, I guess I'll just build "the traditional" switch with stacked sockets and a switch to swap the required lines. I would have prefered the linked one due to the described "protection" to the CIAs but I guess the bare-bones switch method will work too.
