Hey, where is a good place to ask about Commodore peripherals? In particular, I have a couple of SD-2 drives and I purchased a dual-copy upgrade kit that I am finally getting around to installing.
The instructions say to install in U3, which is usually empty. But the included schematics show that U3 is used for the SD-2, giving the drive (apparently) 6k. So, my thought is that I will install it in U4 which shows unoccupied in the schematics, supposedly to give me 8k. The question becomes, is this wasteful for the dual-copy option or anything else? Or perhaps I will just save the extra 4016 for another project.
(And U3 is definitely occupied on the board.)
