TPDD client:flopy2
The Tandy Portable Disk Drive 2 came with a dos called "FLOPPY", on the utility disk. This is a different version than what's on the TPDD1 Utility Disk.
The only way to install it is to bootstrap using the utility disk that came with the drive.
You can buy copies of the TPDD2 Utility Disk from ArcadeShopper
You can also re-create a TPDD2 Utility Disk using a TPDD2 drive, PDD210, and this disk image: File:26-3814.ZIP
