Switcheroo! is a Drive 1-2 switch for Apple Disk ][ compatible devices (devices with a 20 pin ribbon cable) including Disk ][, FloppyEmu, wDrive, etc. It features two 20 pin drive headers (A,B) into which you plug your devices.
The first of two selector switches allows you to select which of the devices (A or B) is Drive 1 (the boot device), with the other device being recognised by the system as Drive 2.
The second selector switch allows you to hide Drive 2 from the system – in this mode the unit functions purely as a Drive A, B switch where one of the devices connected to the A B headers will be Drive 1 and bootable.
Switcheroo! allows you to easily switch the boot device without having to unplug cables (and risk damaging the hardware) – just flip the switch. This is very handy when testing physical disks that you have created from images (copied from an emulated floppy drive) – boot your copy utility off the emulated floppy, load the source disk, copy to physical, flip the switch and test that the physical disk boots.
I recently bought and installed this on my Platinum IIe. I had a wDrive Emulator from KbooHK [ see other blog entry https://vintagegeek.wordpress.com/2019/10/05/wdrive-apple-ii-floppy-drive-emulator-by-kboohk/ ] and a regular Disk ][ 5.25″ Drive. I like the wDrive since you can boot from many disk images, including 3.5 (800k) and larger. But there are some things where the 5.25 with original media is better (more fun).
Here’s my setup with the Switcheroo, the Disk ][ and the wDrive. A little clumsy looking but I just started. [ ignore the db19 drive adapter Card in the background. That’s for a completely different configuration ].
