I have an Arc A310 and have been using it with a Gotek drive running FlashFloppy.
The Gotek has been connected using a Watford Electronics external drive interface that I originally bought to connect a 5.25" drive for transferring files from BBC discs. I have been doing a mix of full disc copies from original Archimedes discs using the Arc itself, and imaging the discs using a Greaseweazle.
I have come across a number of apps that won't run from the hard disk, and some, notably EMR Studio24+, that will only run from ADFS floppy drive 0. This got me thinking about how to swap the drive numbers so the Gotek can be drive 0 and the internal floppy drive 1.
I was reading this thread which looks really interesting, but doesn't provide a solution for the earlier Archimedes machines.
So, as an alternative solution, I have homemade an adapted 'clone' of a Cumana floppy disc buffer with added links to allow SEL0 and SEL1 to be swapped. I have also swapped SEL0 and SEL1 going to the external drive so that it can remain set as drive 0.
A further addition has been the design of a 3D printed podule plate for the 34-way ribbon connector, a BBC style power connector, and a switch to allow the drive swap to be selected without opening the case.
If there's enough interest I can share the designs. The schematics are in OrCAD, PCB layout in EasyPC and 3D model in FreeCAD.
