This is a recreation of the DoubleDos card made by Tymac back in the early 1980’s or perhaps even late 1970’s. The card plugs into the PROM connectors on your Disk II Controller Card (after you remove the originals) and then via a switch you can toggle between 13 and 16 sector PROMs (DOS 3.2 and DOS 3.3). You can flip the switch while the computer is on, but it should be rebooted immediately such that the version of DOS matches what's loaded from the floppy disk.
There is a header on the top of the card where you can either use jumpers to select between 13 and 16 sector, or you can attach the included switch to allow the switching from outside the computer. Installation is easy, just remove the PROMs on your controller card (save them away in a safe place), align the card and press them together.
Requirements:
[1] A working Disk II controller card (can have either 13 or 16 sector PROMs because you remove them)
[2] The appropriate working 13 sector (DOS 3.2) or 16 sector (DOS3.3) floppy disks.
